      is this a good enough reason to cut down rainforest
  • The wood cut down is sold as timber and used as fuel.
    • Aman DC
       
      people used timber to make fuel
  • There are also social reasons for cutting down the trees. Transport links. Roads and railways are needed to move goods and people. Settlements. Modern cities such as Manaus in Brazil and Jakarta in Indonesia have been developed in areas that were once were tropical rainforest.

  • There are economic reasons for countries to cut down their rainforests. Farmland is made. This is both arable land which is used for tropical crops such as cassava and bananas, and grass land which is used for livestock farming, mainly cattle ranching. This farmland, as well as providing food, gives employment and earns money in export earnings for the country. The wood cut down is sold as timber and used as fuel. Tropical hardwoods are much in demand for use in building and furniture. The main markets for the tropical hardwoods are in the developed world. It will allow the mining of minerals. Many important ores such as bauxite and iron ore have been found in tropical rainforest areas. The most economical way to remove the rocks is often by opencast mining, which means that the trees have to be cut down. The produce power and water supplies. Rivers have been dammed to make large reservoirs for Hydro-Electric Power schemes. An example is the Sobradino Dam on the San Francisco River in Brazil.

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.

Rainforests - 0 views

  • Rainforests are important for many reasons. Very importantly, the plants clean the air. By absorbing carbon dioxide they help slow down the greenhouse effect. Rainforest trees store carbon dioxide in their roots, stems, branches, and leaves. Destroying the rainforests causes carbon dioxide to be released, which makes the greenhouse effect worse.
  • Rainforests actually create the rain that gives them their name. As water evaporates from the forest back into the atmosphere, it forms clouds above the rainforest. The clouds release the water back as rain, which evaporates into the atmosphere, and so on in a cycle. Rainforests affect the rain and weather patterns in other parts of the world. Removal of the forests can change the rainfall patterns elsewhere.

      Wow!
  • Commercial logging is the single largest cause of rainforest destruction, both directly and indirectly. Other activities destroying the rainforest, including clearing land for grazing animals and subsistence farming. The simple fact is that people are destroying the Amazon rainforest and the rest of the rainforests of the world because "they can't see the forest for the trees."

  • At least 80% of the developed world's diet originated in the tropical rainforest. Its bountiful gifts to the world include fruits like avocados, coconuts, figs, oranges, lemons, grapefruit, bananas, guavas, pineapples, mangos and tomatoes; vegetables including corn, potatoes, rice, winter squash and yams; spices like black pepper, cayenne, chocolate, cinnamon, cloves, ginger, sugar cane, tumeric, coffee and vanilla and nuts including Brazil nuts and cashews.

  • Two drugs obtained from a rainforest plant known as the Madagascar periwinkle, now extinct in the wild due to deforestation of the Madagascar rainforest, have increased the chances of survival for children with leukemia from 20 percent to 80 percent. Think about it: eight out of ten children are now saved, rather than eight of ten children dying from leukemia. How many children have been spared and how many more will continue to be spared because of this single rainforest plant? What if we had failed to discover this one important plant among millions before human activities had led to its extinction? When our remaining rainforests are gone, the rare plants and animals will be lost forever-and so will the possible cures for diseases like cancer they can provide.
    • Marius S
       
      Because of deforestation, all this has happened!
  • Rainforests have evolved over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and breathing renewable natural resources that for eons, by virtue of their richness in both animal and plant species, have contributed a wealth of resources for the survival and well-being of humankind. These resources have included basic food supplies, clothing, shelter, fuel, spices, industrial raw materials, and medicine for all those who have lived in the majesty of the forest. However, the inner dynamics of a tropical rainforest is an intricate and fragile system. Everything is so interdependent that upsetting one part can lead to unknown damage or even destruction of the whole. Sadly, it has taken only a century of human intervention to destroy what nature designed to last forever. The scale of human pressures on ecosystems everywhere has increased enormously in the last few decades. Since 1980 the global economy has tripled in size and the world population has increased by 30 percent. Consumption of everything on the planet has risen- at a cost to our ecosystems. In 2001, The World Resources Institute estimated that the demand for rice, wheat, and corn is expected to grow by 40% by 2020, increasing irrigation water demands by 50% or more. They further reported that the demand for wood could double by the year 2050; unfortunately, it is still the tropical forests of the world that supply the bulk of the world's demand for wood.
    • Yen Yu C
       
      rainforest could be gone if the wood suplies keeps going up like this!
  • In 1950, about 15 percent of the Earth's land surface was covered by rainforest. Today, more than half has already gone up in smoke. In fewer than fifty years, more than half of the world's tropical rainforests have fallen victim to fire and the chain saw, and the rate of destruction is still accelerating. Unbelievably, more than 200,000 acres of rainforest are burned every day. That is more than 150 acres lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rainforest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year. If nothing is done to curb this trend, the entire Amazon could well be gone within fifty years. Massive deforestation brings with it many ugly consequences-air and water pollution, soil erosion, malaria epidemics, the release of carbon dioxide into the atmosphere, the eviction and decimation of indigenous Indian tribes, and the loss of biodiversity through extinction of plants and animals. Fewer rainforests mean less rain, less oxygen for us to breathe, and an increased threat from global warming.

      that is just scary but it is something we must know inorder for someone to solve the problem someday...i guess
  • But who is really to blame? Consider what we industrialized Americans have done to our own homeland. We converted 90 percent of North America's virgin forests into firewood, shingles, furniture, railroad ties, and paper. Other industrialized countries have done no better. Malaysia, Indonesia, Brazil, and other tropical countries with rainforests are often branded as "environmental villains" of the world, mainly because of their reported levels of destruction of their rainforests. But despite the levels of deforestation, up to 60 percent of their territory is still covered by natural tropical forests. In fact, today, much of the pressures on their remaining rainforests comes from servicing the needs and markets for wood products in industrialized countries that have already depleted their own natural resources. Industrial countries would not be buying rainforest hardwoods and timber had we not cut down our own trees long ago, nor would poachers in the Amazon jungle be slaughtering jaguar, ocelot, caiman, and otter if we did not provide lucrative markets for their skins in Berlin, Paris, and Tokyo.

    • Gurupranav G
       
      Useful for my Q4
  • he problem and the solution of the destruction of the rainforest are both economic. Governments need money to service their debts, squatters and settlers need money to feed their families, and companies need to make profits. The simple fact is that the rainforest is being destroyed for the income and profits it yields, however fleeting. Money still makes the world go around . . . even in South America and even in the rainforest. But this also means that if landowners, governments, and those living in the rainforest today were given a viable economic reason not to destroy the rainforest, it could and would be saved. And this viable economic alternative does exist, and it is working today. Many organizations have demonstrated that if the medicinal plants, fruits, nuts, oils, and other resources like rubber, chocolate, and chicle (used to make chewing gums) are harvested sustainably, rainforest land has much more economic value today and more long-term income and profits for the future than if just timber is harvested or burned down for cattle or farming operations. In fact, the latest statistics prove that rainforest land converted to cattle operations yields the landowner $60 per acre; if timber is harvested, the land is worth $400 per acre. However, if medicinal plants, fruits, nuts, rubber, chocolate, and other renewable and sustainable resources are harvested, the land will yield the landowner $2,400 per acre. This value provides an income not only today, but year after year - for generations. These sustainable resources - not the trees - are the true wealth of the rainforest.

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

  • An increase in tourism has increased economic support, allowing more revenue to go into the protection of the habitat. Tourism can contribute directly to the conservation of sensitive areas and habitat. Revenue from park-entrance fees and similar sources can be utilised specifically to pay for the protection and management of environmentally sensitive areas. Revenue from taxation and tourism provides an additional incentive for governments to contribute revenue to the protection of the forest. Tourism also has the potential to increase public appreciation of the environment and to spread awareness of environmental problems when it brings people into closer contact with the environment. Such increased awareness can induce more environmentally conscious behavior. Tourism has had a positive effect on wildlife preservation and protection efforts, notably in Africa but also in South America, Asia, Australia, and the South Pacific.[14]

Deforestation - Wikipedia, the free encyclopedia - 0 views

  • Deforestation is the clearance of naturally occurring forests by the processes of logging and/or burning of trees in a forested area. There are several reasons deforestation occurs: trees or derived charcoal can be sold as a commodity and used by humans, while cleared land is used as pasture, plantations of commodities and human settlement. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. Deforested regions typically incur signicifant adverse soil erosion and frequently degrade into wasteland. Disregard or ignorance of intrinsic value, lack of ascribed value, lax forest management and deficient environmental law are some of the factors that allow deforestation to occur on a large scale. In many countries, deforestation is an ongoing issue that is causing extinction, changes to climatic conditions, desertification, and displacement of indigenous people. However, among countries with a per capita GDP of at least $4,600, net deforestation rates have ceased to increase

Rainforest Animals - 5 views

  • 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.

      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.

      This may help me answer my question on the interdependence of the animals of a rainforest, and it may help you out too, if you are looking at the interdependence of the animals in a rainforest
  • 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.

      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

  • 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.

      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!

  • 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!

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

  • 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.
  • Some traditional rainforest cultures still live in the forests. They travel as a group to collect and hunt food. As rainforests are destroyed, so are the homes of these interesting and amazing people.

  • 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.

Dwarf - Wikipedia, the free encyclopedia - 0 views

  • A Dwarf is a creature from Germanic mythologies, fairy tales, fantasy fiction, and role-playing games. It usually has magical talents, often involving metallurgy. The original concept of Dwarves is very difficult to determine. Sources have gradually given Dwarves more comical and superstitious roles[1]. Dwarves were certainly humanoid, but sources differ over their lifestyles, and their similarity to Elves. They may have had a strong associations with death[2][3]: paled skin; dark hair; connections with the earth; their role in mythology. They followed animistic traditions, showing similarities to such concepts of the dead. They were similar to others from the 'Vættir' family, such as Elves.[2]

  • Traditionally, the plural of dwarf was "dwarfs", especially when referring to actual humans with dwarfism, but ever since J. R. R. Tolkien used Dwarves in his fantasy novel The Hobbit, the subsequent The Lord of the Rings (often published in three volumes), and the posthumously published The Silmarillion, the plural forms "dwarfs" has been replaced by "Dwarves". Tolkien, who was fond of low philological jests, also suggested two other plural forms, Dwarrows and Dwerrows; but he never used them in his writings, apart from the name 'Dwarrowdelf', the Western name for Khazad-dûm or Moria, which was, inside his fiction, a calque of the Westron name Phurunargian. His Dwarves' name for themselves was Khazâd, singular probably Khuzd. 'Dwarrows' is the Middle English plural of 'Dwerg' or 'Dwerf' ('Dwarf'), and derives from the Old English 'Dweorgas', plural of 'Dweorh' or 'Dweorg'.
  • Dwarves in Tolkien are long-lived, living nearly four times the age of man (about 250 years), but are not prolific breeders, having children rarely and spaced far apart, and having few women among them. Dwarvish children are cherished by their parents, and are defended at all costs from their traditional enemies, such as Orcs. A longstanding enmity between normal Dwarves and Elves is also a staple of the racial conception.
  • A long standing source of interest (and humour) comes from the allusion of Tolkien to female Dwarves having beards, which was borrowed by other writers. Essentially, Tolkien developed a rational explanation for why female Dwarves are never encountered in the story, by elaborating that female Dwarves never travel abroad, and look so much like Dwarf men that visitors to Dwarf cities cannot immediately spot them. In addition to being rare creatures they are perhaps not often featured in many fantasy milieu for this reason. Tolkien writes his Dwarf-women are "in voice and appearance, and in garb if they must go on a journey, so like to dwarf-men that the eyes and ears of the other peoples cannot tell them apart." This, he writes, leads to the belief that Dwarves grow out of stone[15]. In The Chronicles of Narnia, in fact, C. S. Lewis, who was a friend of Tolkien, describes his Dwarfs as doing just this, and it is possible that Tolkien was ribbing Lewis in making this point. Interestingly, though, Lewis' all-male Dwarfs are capable of mixing with humans to make half-Dwarfs, such as Doctor Cornelius, the tutor of Prince Caspian (In the 2008 adaption of Prince Caspian, female Dwarfs are shown as archers along with the males, though these female Dwarfs are shown to be beardless). In later writings, Tolkien directly states that his female Dwarves have beards "from the beginning of their lives", as do the males[16].
