Deforestation - 0 views

  • What is Deforestation Deforestation is defined as the destruction of forested land. It has proved to be a major problem all over world. However, the rates of destruction of forests are particularly high in the tropics. Causes of Deforestation The causes of deforestation vary form place to place. The most common causes, however, are logging, agricultural expansion, wars, and mining, Effects of Deforestation Deforestation has been the cause of many problems facing the world today such as erosions, loss of biodiversity through extinction of plant and animal species, and increased atmospheric carbon dioxide. Importnace of Vegetation Deforestation consequently decrease the supply of oxygen found on earth. Oxygen is essential to the existence of all living things and without it every living creature (including humans) will not be able to sustain life. In addition, forests provide homes for many important species such as the Northern Spotted Owl which can only survive in the northwestern United States . Furthermore, forests prevent desertification by replenishing nutrients in the land. These are just a few reasons why forests are soon important.

Land mine - Wikipedia, the free encyclopedia - 1 views

  •  
    "A land mine is a target (person or vehicle) triggered explosive weapon . Their non-explosive predecessors (caltrops, stakes and spikes) have been used on the battlefield since ancient times. Landmines were designed to be used to deter, channel, delay and kill an enemy. They have been used in various formats, for centuries and have featured in all major conflicts. Land mines are force multipliers , meaning that they may increase the efficiency of a force without requiring more personnel. The name originates from the practice of mining , where tunnels were dug under enemy fortifications or forces. These tunnels ("mines") were first collapsed to destroy fortifications above, and later filled with explosives and detonated. Land mines generally refer to devices specifically manufactured for this purpose, as distinguished from improvised explosive devices ("IEDs"). The use of land mines is controversial because they are indiscriminate weapons, harming soldier and civilian alike. They remain dangerous after the conflict in which they were deployed has ended, killing and injuring civilians and rendering land impassable and unusable for decades. To make matters worse, many factions have not kept accurate records (or any at all) of the exact locations of their minefields, making removal efforts painstakingly slow. These facts pose serious difficulties in many developing nations where the presence of mines hampers resettlement, agriculture, and tourism. The International Campaign to Ban Landmines campaigned successfully to prohibit their use, culminating in the 1997 Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on their Destruction, known informally as the Ottawa Treaty . As of 2007, a total of 158 nations have agreed to the treaty. Thirty-seven countries have not agreed to the ban, including China , India , Israel , Pakistan

Rainforest Biomes - 0 views

  • Many species of animal life can be found in the rain forest. Common characteristics found among mammals and birds (and reptiles and amphibians, too) include adaptations to a life in the trees, such as the prehensile tails of New World monkeys. Other characteristics are bright colors and sharp patterns, loud vocalizations, and diets heavy on fruits. Insects make up the largest single group of animals that live in tropical forests. They include brightly colored butterflies, mosquitoes, camouflaged stick insects, and huge colonies of ants. The Amazon river basin rainforest contains a wider variety of plant and animal life than any other biome in the world. The second largest population of plant and animal life can be found in scattered locations and islands of Southeast Asia. The lowest variety can be found in Africa. There may be 40 to 100 different species in 2.5 acres ( 1 hectare) of a tropical rain forest.   When early explorers first discovered the rainforests of Africa, Southeast Asia and South America, they They were amazed by the dense growth, trees with giant buttresses, vines and epiphytes . The tropical vegetation grew so dense that it was difficult to cut one's way through it. It was thought at the time that the soil of a rainforest must be very fertile, filled with nutrients, enabling it to support the immense trees and other vegetation they found. Today we know that the soil of the tropical rainforests is shallow, very poor in nutrients and almost without soluble minerals. Thousands of years of heavy rains have washed away the nutrients in the soil obtained from weathered rocks. The rainforest has a very short nutrient cycle. Nutrients generally stay in an ecosystem by being recycled and in a rainforest are mainly found in the living plants and the layers of decomposing leaf litter. Various species of decomposers like insects, bacteria, and fungi make quick work of turning dead plant and animal matter into nutrients. Plants take up these nutrients the moment they are released. A study in the Amazon rainforest found that 99% of nutrients are held in root mats. When a rainforest is burned or cut down the nutrients are removed from the ecosystem. The soil can only be used for a very short time before it becomes completely depleted of all nutrients.

  • Besides these four layers, a shrub/sapling layer receives about 3 % of the light that filters in through the canopies. These stunted trees are capable of a sudden growth surge when a gap in the canopy opens above them. The air beneath the lower canopy is almost always humid. The trees themselves give off water through the pores (stomata) of their leaves. This process, called transpiration, can account for as much as half of the precipitation in the rain forest. Rainforest plants have made many adaptations to their environment. With over 80 inches of rain per year, plants have made adaptations that helps them shed water off their leaves quickly so the branches don't get weighed down and break. Many plants have drip tips and grooved leaves, and some leaves have oily coatings to shed water. To absorb as much sunlight as possible on the dark understory, leaves are very large. Some trees have leaf stalks that turn with the movement of the sun so they always absorb the maximum amount of light. Leaves in the upper canopy are dark green, small and leathery to reduce water loss in the strong sunlight. Some trees will grow large leaves at the lower canopy level and small leaves in the upper canopy. Other plants grow in the upper canopy on larger trees to get sunlight. These are the epiphytes such as orchids and bromeliads. Many trees have buttress and stilt roots for extra support in the shallow, wet soil of the rainforests. Over 2,500 species of vines grow in the rainforest. Lianas start off as small shrubs that grow on the forest floor. To reach the sunlight in the upper canopy it sends out tendrils to grab sapling trees. The liana and the tree grow towards the canopy together. The vines grow from one tree to another and make up 40% of the canopy leaves. The rattan vine has spikes on the underside of its leaves that point backwards to grab onto sapling trees. Other "strangler" vines will use trees as support and grow thicker and thicker as they reach the canopy, strangling its host tree. They look like trees whose centers have been hollowed out. Dominant species do not exist in tropical rainforests. Lowland dipterocarp forest can consist of many different species of Dipterocarpaceae, but not all of the same species. Trees of the same species are very seldom found growing close together. This bio diversity and separation of the species prevents mass contamination and die-off from disease or insect infestation. Bio diversity also insures that there will be enough pollinators to take care of each species' needs. Animals depend on the staggered blooming and fruiting of rainforest plants to supply them with a year-round source of food.

      Again, another useful peice of info if you are looking at the diversity of plants in the rainforest.
  • There are four very distinct layers of trees in a tropical rain forest. These layers have been identified as the emergent, upper canopy, understory, and forest floor. Emergent trees are spaced wide apart, and are 100 to 240 feet tall with umbrella-shaped canopies that grow above the forest. Because emergent trees are exposed to drying winds, they tend to have small, pointed leaves. Some species lose their leaves during the brief dry season in monsoon rainforests. These giant trees have straight, smooth trunks with few branches. Their root system is very shallow, and to support their size they grow buttresses that can spread out to a distance of 30 feet. The upper canopy of 60 to 130 foot trees allows light to be easily available at the top of this layer, but greatly reduced any light below it. Most of the rainforest's animals live in the upper canopy. There is so much food available at this level that some animals never go down to the forest floor. The leaves have "drip spouts" that allows rain to run off. This keeps them dry and prevents mold and mildew from forming in the humid environment. The understory, or lower canopy, consists of 60 foot trees. This layer is made up of the trunks of canopy trees, shrubs, plants and small trees. There is little air movement. As a result the humidity is constantly high. This level is in constant shade. The forest floor is usually completely shaded, except where a canopy tree has fallen and created an opening. Most areas of the forest floor receive so little light that few bushes or herbs can grow there. As a result, a person can easily walk through most parts of a tropical rain forest. Less than 1 % of the light that strikes the top of the forest penetrates to the forest floor. The top soil is very thin and of poor quality. A lot of litter falls to the ground where it is quickly broken down by decomposers like termites, earthworms and fungi. The heat and humidity further help to break down the litter. This organic matter is then just as quickly absorbed by the trees' shallow roots

  • The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. In monsoonal areas, there is a real dry season. Almost all rain forests lie near the equator. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rain forests. Tropical rainforests produce 40% of Earth's oxygen. A tropical rain forest has more kinds of trees than any other area in the world. Scientists have counted about 100 to 300 species in one 2 1/2-acre (1-hectare) area in South America. Seventy percent of the plants in the rainforest are trees. About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, and is used as an anesthetic and to relax muscles during surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with lymphocytic leukemia has a 99% chance that the disease will go into remission because of the rosy periwinkle. More than 1,400 varieties of tropical plants are thought to be potential cures for cancer. All tropical rain forests resemble one another in some ways. Many of the trees have straight trunks that don't branch out for 100 feet or more. There is no sense in growing branches below the canopy where there is little light. The majority of the trees have smooth, thin bark because there is no need to protect the them from water loss and freezing temperatures. It also makes it difficult for epiphytes and plant parasites to get a hold on the trunks. The bark of different species is so similar that it is difficult to identify a tree by its bark. Many trees can only be identified by their flowers. Despite these differences, each of the three largest rainforests--the American, the African, and the Asian--has a different group of animal and plant species. Each rain forest has many species of monkeys, all of which differ from the species of the other two rain forests. In addition, different areas of the same rain forest may have different species. Many kinds of trees that grow in the mountains of the Amazon rain forest do not grow in the lowlands of that same forest.

The Food Chain - 0 views

    The Food Chain RealAudio Click here to be joined by your audio host! What is the difference between the 'Food Chain' and 'Food Web?' A popular misnomer, the 'food chain' is not actually a linear chain but a complex web. Energy is passed from one organism to another in a complex network like a spider's web. The food chain consists of four main parts: * The Sun, which provides the energy for everything on the planet. * Producers: these include all green plants. These are also known as autotrophs, since they make their own food. Producers are able to harness the energy of the sun to make food. Ultimately, every (aerobic) organism is dependent on plants for oxygen (which is the waste product from photosynthesis) and food (which is produced in the form of glucose through photosynthesis). They make up the bulk of the food chain or web. * Consumers: In short, consumers are every organism that eats something else. They include herbivores (animals that eat plants), carnivores (animals that eat other animals), parasites (animals that live off of other organisms by harming it), and scavengers (animals that eat dead animal carcasses). Primary consumers are the herbivores, and are the second largest biomass in an ecosystem. The animals that eat the herbivores (carnivores) make up the third largest biomass, and are also known as secondary consumers. This continues with tertiary consumers, etc. * Decomposers: These are mainly bacteria and fungi that convert dead matter into gases such as carbon and nitrogen to be released back into the air, soil, or water. Fungi, and other organisms that break down dead organic matter are known as saprophytes. Even though most of us hate those mushrooms or molds, they actually play a very important role. Without decomposers, the earth would be covered in trash. Decomposers are necessary since they recycle the nutrients to be used again by producers. This table shows the relational biomass of each of the major g

Tropical Rainforest- Trivia & Facts on Saving - 0 views

  • Today, we know that the soil of the tropical rainforests is thin and very low in nutrients. Decomposers like leaf-cutter ants, termites, bacteria, and fungi quickly turn falling leaves and dead organisms into nutrients. Plants take up these nutrients the moment they are available, so they don’t get a chance to enrich the soil. Keeping Tropical Rainforests Healthy Conservation of tropical rainforests should be easy. They have survived for millions of years. The trick to keeping them healthy is to not take too much too fast. This gives the rainforests time to recover from human activities like logging. But many countries that have tropical rainforests are poor. They can make money by cutting down and developing the rainforests. But uncontrolled development results in deforestation

      About the rainforest cycle. (First Paragraph)
  • Rainforests have 170,000 of the world's 400,000 known plant species. The United States has 81 species of frogs, while Madagascar (which is smaller than Texas) may have 300 species. Europe has 321 butterfly species, while Manu National Park in the tropical rainforest of Peru has 1,300 species! The world’s only species of flying snake and lizard live in the Borneo rainforest. The largest catfish in the world lives in a tropical rainforest river in Vietnam. It weighs over 300 kg. About one-quarter of all the medicines we use come from rainforest plants. Curare comes from a tropical vine. It is used as an anesthetic and to relax muscles during heart surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with leukemia has a 99% chance that the disease will go into remission because of the rosy periwinkle. More than 1,400 varieties of tropical plants might be potential cures for cancer.

  • More than half the species on Earth are found in tropical rainforests. Many species living in these forests have never before been seen or studied by scientists. Most of these unknown species are insects, like moths.
  • Tropical rainforests are wet nearly all the time. They get lots of rain all year long, but they also help make rain through evaporation. Tropical rainforests help regulate weather all over the world.
  • Tropical rainforests are found in a narrow region around the equator that is known as the tropics. The climate is rainy and the temperatures are warm and nearly the same every day. The sun and the rain combine to create an environment that is very humid. This climate is ideal for the growth of many kinds of green plants.
  • Many different frog species live in the canopy of the rainforest. Most spend their entire lives in the canopy. They lay their eggs in little pools of water held in leaves instead of in ponds or streams.
  • Tropical rainforest plants have many adaptations for living in the forest. Some collect all their water from the air. For this reason, many of them have very large leaves. Others have flexible stems that allow them to bend and follow the sunlight so they can carry out photosynthesis all day.

Tiger - Wikipedia, the free encyclopedia - 0 views

  • Highly adaptable, tigers range from the Siberian taiga, to open grasslands, to tropical mangrove swamps. They are territorial and generally solitary animals, often requiring large contiguous areas of habitat that support their prey demands. This, coupled with the fact that they are endemic to some of the more densely populated places on earth, has caused significant conflicts with humans. Of the nine subspecies of modern tiger, three are extinct and the remaining six are classified as endangered, some critically so. The primary direct causes are habitat destruction and fragmentation, and hunting. Their historical range, which once reached from Mesopotamia and the Caucasus through most of South and East Asia, has been radically reduced. While all surviving species are under formal protection, poaching, habitat destruction and inbreeding depression continue to be threats.
  • Tigers are perhaps the most recognisable of all the cats (with the possible exception of the lion). They typically have rusty-reddish to brown-rusty coats, a whitish medial and ventral area, a white "fringe" that surrounds the face, and stripes that vary from brown or gray to pure black.
  • Main article: Golden tabby A rare golden tabby/strawberry tiger at the Buffalo Zoo. In addition, another recessive gene may create a very unusual "golden tabby" colour variation, sometimes known as "strawberry." Golden tabby tigers have light gold fur, pale legs and faint orange stripes. Their fur tends to be much thicker than normal.[50] There are extremely few golden tabby tigers in captivity, around 30 in all. Like white tigers, strawberry tigers are invariably at least part Bengal. Some golden tabby tigers, called heterozygous tigers, carry the white tiger gene, and when two such tigers are mated, can produce some stripeless white offspring. Both white and golden tabby tigers tend to be larger than average Bengal tigers.

Primates - 0 views

  • Primates are a group of mammals that include prosimians, monkeys, and apes. Humans are primates, too. We are a type of ape. Most primates have hands and feet that can grasp, and many have tails. There are about 230 primate species. Most primates are found in tropical environments. The only great exception to this is humans. We live all over the planet. Almost all primates eat both plants and animals. Most primates are threatened or endangered.

Biomes - 0 views

  • Shrub and scrubland biomes are found in dry, temperate area. They have mild winters and very hot summers. Dry weather and lightening storms sometimes cause flash floods during the summer. Flash fires start and spread quickly. They make room for new plants to grow by burning the large, older plants. The heat of the fire causes seed shells to crack. After the fire, the seeds sprout and grow into new plants. The main plants are low-growing woody plants with evergreen leaves. These plants have a tough skin that holds in moisture and thorns that protect the plants from grazing animals. Many plants have long roots that enable them to find water underground. Some suck water from the stems of other plants.

The Tropical Rainforest: Why we should care | El Bosque Nuevo - 1 views

  • The rainforest provides habitat for various species of animals. The canopy, trunk, root system, and even the fallen leaves provide a place for these creatures to live and thrive. What happens when rainforests are destroyed? First, all of the trees, underbrush and the animals not able to escape are killed. Many animals that escape migrate to an area already populated. Since the land will only support a limited number of any species, only a few will survive. At the best we will only have lost those individuals without a habitat. It is possibly, however, that the entire population will uses up all available resources and spirals into extinction

  • The identification, ongoing protection and presentatiosn of cultural values is paramount. This includes cultural sites and their traditional knowledge (sometimes referred to as intellectual and cultural property rights) such as food and medicine resources. They want to be able to hunt and gather their traditional foods and other resources, while managing impacts which have the potential to impair these activities through disturbance and habitat destruction. Other important aspirations relate to the future of Rainforest Aboriginal people's communities and their survival into the 21st century. Many Rainforest Aboriginal people want to get more involved in cultural tourism because it means they can present their culture and benefit economically. One of the most heart-felt aspirations Rainforest Aboriginal people have is to get secure title to their traditional lands to ensure the integrity and survival of their cultures.

  • Caring For Our Country The TAFE Caring For Country Program started in 1990 at the request of North Queensland Aboriginal communities who wanted culturally appropriate ranger training. The Diploma level course runs for four years and is equivalent to tertiary education. Aboriginal rangers have unique skills as they are trained to use both traditional knowledge and contemporary management practices to preserve cultural and natural values. Practical skills taught include such things as map reading, site surveys, animal and plant field skills, visitor facility management, first aid and office management. An ecological component includes vegetation management and feral animal control as well as traditional knowledge. Archaeological and anthropological knowledge and techniques are gained in class as well as on sites in the field.
  • Which Way Our Future Aboriginal people are very proud of their indigenous heritage. They want the importance of their culture recognised, respected and protected. To ensure the ongoing survival of their culture, Rainforest Aboriginal people have been negotiating for shared management of their traditional country with government agencies. Rainforest Aboriginal people want to be to be recognised as the traditional land owners of the World Heritage Area with distinct cultures and individual needs. They would like to negotiate plans for their traditional lands and be involved with all aspects of land management decision making, and activities such as tourism and walking tracks planning, fire management, wildlife protection, and on the ground management. Other important goals include ranger training and employment opportunities so that Rainforest Aboriginal people can actively use their customary and contemporary land management knowledge to continue their traditions of managing their country.
  • Aboriginal rangers now work for Aboriginal communities and in some government agencies such as the Queensland Parks and Wildlife Service, looking after rainforest and sea country. Aboriginal rangers are involved in all types of nature conservation and cultural heritage work. They liaise between Elders, Aboriginal community members and government agencies. They build and manage walking tracks for tourists. Rangers carry out surveys on cultural sites and help to manage and protect these sites. They are involved in pest and weed control, and help Government agencies to use controlled fires to maintain the diversity of plants and animals in the World Heritage Area.
  • Rangers also have an important role to play in public education. They visit schools, talk to tourists and the wider community about their work and culture. Cross cultural education and experiences for the wider community and visitors help to promote interracial understanding - an important step towards reconciliation. Aboriginal community rangers are often employed on a part-time basis to work in their communities on land management and cultural heritage protection through funding from the Commonwealth agency, the Aboriginal and Torres Strait Islander Commission (ATSIC) and the Community Development Employment Projects (CDEP). CDEP is similar to the mainstream "work for the dole" (unemployment benefits) program in that these schemes also benefit local communities. A difference is, in some cases, that many Aboriginal people may not have other opportunities to find work or be involved in caring for their country. Many young community rangers find it frustrating to be employed only on CDEP after having done four years of training. Employment of more Aboriginal rangers has the potential to greatly increase the integration of traditional management knowledge and techniques to improve overall management of the World Heritage Area, it is a question of resources. With their Elders, Aboriginal rangers are negotiating with government land management agencies for more permanent, full-time positions managing their country in the Wet Tropics World Heritage Area.

The identification, ongoing protection and presentatiosn of cultural values is paramount. This includes cultural sites and their traditional knowledge (sometimes referred to as intellectual and cultural property rights) such as food and medicine resources. They want to be able to hunt and gather their traditional foods and other resources, while managing impacts which have the potential to impair these activities through disturbance and habitat destruction. Other important aspirations relate to the future of Rainforest Aboriginal people's communities and their survival into the 21st century. Many Rainforest Aboriginal people want to get more involved in cultural tourism because it means they can present their culture and benefit economically. One of the most heart-felt aspirations Rainforest Aboriginal people have is to get secure title to their traditional lands to ensure the integrity and survival of

  • Tropical Rainforest Fast Facts Print Fast Facts Description Tropical rainforests are a type of wet, warm, humid forest. Tropical rainforests have the greatest biodiversity of any other ecosystem on earth. Some scientists believe they house more than half of all living species on earth. 90% of the species found in the tropical rainforest live in the canopy, high above the ground. Location Tropical rainforests are located in the tropics, the area around the warm equator. They are found in areas of Africa, Asia, Australia, and South and Central America. Climate The climate of tropical rainforests is warm and humid with almost continual rain. Most rainforests receive 200-1000 cm of rain a year and have temperatures that rarely drop below 22° C. Issues Tropical rainforests are quickly disappearing as a result of logging and clearing for timber, livestock grazing, plantations, and the harvest of other natural resources. 31 million hectares of tropical rainforest are destroyed each year.  That is an area larger than Poland. Status All tropical rainforests are in great danger of being destroyed. They once covered 14% of the earth’s land surface but now only cover 6%. Some scientists believe that, at the current rate of destruction, the remaining forests could be destroyed in less than 40 years. The state of tropical rainforests should be a priority for all countries and cultures since they provide and regulate the majority of the earth’s clean air and water. ©GLOBIO.org

  • Scientists believe that there is such a great diversity of animals because rainforests are the oldest ecosystem on earth.
  • Many animals species have developed relationships with each other that benefit both species. Birds and mammal species love to eat the tasty fruits provided by trees. Even fish living in the Amazon River rely on fruits dropped from forest trees. In turn, the fruit trees depend upon these animals to eat their fruit, which helps them to spread their seeds to far-off parts of the forest.

    • Thomas C
       
      WHAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  • When rainforests are destroyed, animals living outside the tropics suffer as well. Songbirds, hummingbirds, warblers and thousands of other North American birds spend their winters in rainforests, returning to the same location year after year. Less return north each spring, as few make it through the winter because their habitat has been destroyed. The cutting down of trees is not the only reason for species extinction. Thousands of monkeys and other primates are traded illegally on the international market each year, wanted for their fur, as pets, or for scientific research. Parrots and macaws have also become popular pets; buyers will pay up to $10,000 for one bird. Even the king of the jungle, the jaguar, is in danger of becoming extinct. Its fur is highly valued for use on coats and shoes.

  • Scientists estimate that there are more than 50 million different species of invertebrates living in rainforests. One scientist found 50 different species of ants on a single tree in Peru! You would probably only need a few hours of poking around in a rainforest to find an insect unknown to science.
  • In some cases both species are so dependent upon each other that if one becomes extinct, the other will as well. This nearly happened with trees that relied on the now-extinct dodo birds. They once roamed Mauritius, a tropical island located in the Indian Ocean. They became extinct during the late 19th century when humans overhunted them. The calvaria tree stopped sprouting seeds soon after. Scientists finally concluded that, for the seeds of the calvaria tree to sprout, they needed to first be digested by the dodo bird. By force-feeding the seeds to a domestic turkey, who digested the seeds the same way as the dodo birds, the trees were saved. Unfortunately humans will not be able to save each species in this same way.

  • The constant search for food, water, sunlight and space is a 24-hour pushing and shoving match. With this fierce competition, you may be amazed that so many different species of animals can all live together. But this is actually the cause of the huge number of different species.The main secret lies in the ability of many animals to adapt to eating a specific plant or animal, which few other species are able to eat. Have you ever wondered, for instance, why toucans and parrots have such big beaks? These beaks give them a great advantage over other birds with smaller beaks. The fruits and nuts from many trees have evolved with a tough shell to protect them from predators. In turn toucans and parrots developed large strong beaks, which serves as a nutcracker and provides them with many tasty meals.
    • Gurupranav G
       
      This peice of information will be useful if you are looking at the adaptations of different animals in the rainforest. This is useful for me.
  • Each species has evolved with its own set of unique adaptations, ways of helping them to survive. Every animal has the ability to protect itself from being someone's next meal. The following are just a few of these unique and often bizarre adaptations. CAMOUFLAGE The coloring of some animals acts as protection from their predators. Insects play some of the best hide-and-go-seek in the forest. The "walking stick" is one such insect; it blends in so well with the palm tree it calls its home that no one would notice it unless it moved. Some butterflies, when they close their wings, look exactly like leaves. Camouflage also works in reverse, helping predators, such as boa constrictors, sneak up on unsuspecting animals and surprise them. SLOW AS A SNAIL The three-toed sloth is born with brown fur, but you would never know this by looking at it. The green algae that makes its home in the sloth's fur helps it to blend in with the tops of the trees, the canopy, where it makes its home. But green algae isn't the only thing living in a sloth's fur; it is literally "bugged" with a variety of insects. 978 beetles were once found living on one sloth! The sloth has other clever adaptations. Famous for its snail-like pace; it is one of the slowest-moving animals on earth. (It can even take up to a month to digest its food!) Although its tasty meat would make a good meal for jaguars and other predators, most do not notice the sloth as it hangs quietly in the trees, high up in the canopy. DEADLY CREATURES Other animals want to announce their presence to the whole forest. Armed with dangerous poisons used in life-threatening situations, their bright colors warn predators to stay away. The coral snake of the Amazon, with its brilliant red, yellow, and black coloring, is recognized as one of the most beautiful snakes in the world, But don't admire its beauty too long; its deadly poison can kill within seconds The poison arrow frog also stands out with its brightly colored skin. Its skin produces some of the strongest natural poison in the world, which Indigenous people often use for hunting purposes. Another animal with no friends is the hoatzin. Often called the stinkbird, it produces a horrible smell to scare

  • An average of 35 species becomes extinct every day in the world's tropical rainforests.

      Most of these species, we haven't discovered their uses yet. We don't care that we don't even know what they are and never will
  • Rivers have become both overfished and polluted. Gillnets now allow fishermen to kill huge amounts of fish at a time. They often use only the larger and more profitable fish, dumping the dead smaller fish and other animals such as dolphins back into the rivers.
    • Chloe W
       
      This is terrible. We are losing our air supply, and now our water supply is getting polluted. I hope we can stop it.
  • Tropical rainforests are home to many of the strangest-looking and most beautiful, largest and smallest, most dangerous and least frightening, loudest and quietest animals on earth. You've probably heard of some of them; jaguars, toucans, parrots, gorillas, and tarantulas all make their homes in tropical rainforests. But have you ever heard of the aye-aye? Or the okapi? There are so many fascinating animals in tropical rainforests that millions haven't been named or even identified yet. In fact, about half of all the world's species live in tropical rainforests.

      How can we save the animals
  • During the Ice Ages, the last of which occurred about 10,000 years ago, the frozen areas of the North and South Poles spread over much of the earth, causing huge numbers of extinctions. But the giant freeze did not reach many tropical rainforests. Therefore, these plants and animals could continue to evolve, developing into the most diverse and complex ecosystems on earth. The nearly perfect conditions for life also help contribute to the great number of species. With temperatures constant at 75 -80 degrees F. the whole year, animals don't have to worry about freezing during cold winters or finding shade in the hot summers. They rarely have to search for water, as rain falls almost every day in tropical rainforests. Some rainforest species have populations that number in the millions. Other species consist of only a few dozen individuals. Living in limited areas, most of these species are endemic, or found nowhere else on earth. The maues marmoset, a species of monkey, wasn't discovered until recently. Its entire tiny population lives within a few square miles in the Amazon rainforest. It is so small, it could sit in a person's hand!

      this might help me in my research as i am researching on insects and the interesting ways of decieving their predators
  • Leaf-cutter, or parasol ants, can rightfully be called the world's first farmers. They climb trees up to 100-feet tall and cut out small pieces of leaves. They then carry these fragments, weighing as much as 50 times their body weight, back to their homes. Sometimes they must travel 200 feet, equal to an average human walking about 6 miles with 5,000 lbs. on his/her back! The forest floor is converted to a maze of busy highways full of these moving leaf fragments. These ants don't eat the leaves they have collected, but instead bury them underground. The combination of leaves and substances that the ants produce such as saliva allows a type of fungus to grow. This fungus is the only food that the ants need to eat. Azteca ants live on the swollen thorn acacia tree, which offers the ants everything needed for survival - lodging, water, and food for themselves and their young. In return, the ants protect the trees from predators. Whenever the ants feel something brush against the tree, they rush to fiercely fight the intruder. They also protect it from vines and other competing plants that would otherwise strangle it. As a result, nothing can grow near these trees. They are the only trees with a built-in alarm system!

  • What We Can Do To Save Them Learn and Share Information The first step toward saving the rainforests is to learn about them. Through reading we can explore the wonders of the rainforests without ever visiting them. Once we learn about them we need to share our knowledge with others. Letters to our congressional representatives can influence those in power and encourage discussion on the rainforest. And by talking to friends about the rainforests another person can become active in saving the them. Join Groups We can join a conservation group. The group can tell us what needs to be done to save the rainforests and how we can help. Or we can volunteer with the local zoo, nature center, botanical garden, or museum. We can learn a lot from the professionals that work there. Begin at Home Our own homes provide many chances to help save the rainforests. We can recycle all reusable materials. We can learn to use products made from rainforests in a thoughtful way. And we can protect living things in our own backyard. The plants and animals there also need protection. Ask Questions We can protect illegal trade of animals and plants from the wild by asking questions. We need to ask store owners if the plants and animals they sell were taken from the wild. Unless we ask questions, illegal trade will continue. Illegal trade leads to endangered species and extinction. Think Globally And we can encourage our local or national conservation organizations to help save the rainforests. It is necessary for all of us to be aware of and help with saving the rainforests. Although the rainforests cover on ly a small area of the world, far away from many of our homes, they have an effect on all of us.

Rain Forest Destruction, Shameful Result of Our Spiritual Crisis - 0 views

  • Indeed, tropical forest is a victim of a spiritual crisis in humanity. The destruction of tropical forest reflects an all too-widespread willingness to submit to an economic determinism every bit as rigid as that of Marx. Egbert Giles Leigh Jr. (1) Rain Forest Destruction, Madagascar Photo: Jonathan TalbotWorld Resources Institute, 2003 We learn from Columbia Encyclopedia that in very early times forests covered virtually the whole land surface of the Earth, apart from the areas of perpetual snow (such as the north pole). (2) And as recently as 19 th century, tropical rain forests in their own right covered around 20% of all the dry land area of the Earth, but this figure was only 7% by the end of the 20 th century. (3) Probably the main fundamental factor that has been invariably pushing rain forest destruction more and more over the decades and indeed centuries, is the demand for the rain forest as a enormous economic and social resource. First of all, tropical rain forests are “treasure troves of nature” – they contain endless supplies of resources widely used in human societies, such as food, timber, raw materials etc. Second, rain forests cover huge swathes of land. And the land has always been a limited resource required for accommodation of ever growing human populations.
