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 - 0 views

  • birds live in the canopy (upper leaves of the trees) and in the emergents (the tops of the tallest trees). Large animals (like jaguars) generally live on the forest floor, but others (like howler monkeys and sloths) are arboreal (living in trees). Insects are found almost everywhere.

      Put in report & find out more about where animals live
  • Some animals try to convince predators that they are bigger and more fierce than they really are. For example, the larva of the lobster moth (Stauropus fagi), whose larva looks like a scorpion, but is in fact completely defenseless. Many butterflies have large "eye" designs on their wings. This makes them look like the head of a very large animal instead of a harmless butterfly, and scares many predators away.

Importance of the Rainforest - 0 views

  • What is a Rainforest?
  • Rainforests are extremely important in the ecology of the Earth. The plants of the rainforest generate much of the Earth's oxygen. These plants are also very important to people in other ways; many are used in new drugs that fight disease and illness.

  • ropical rainforests are found in a belt around the equator of the Earth. There are tropical rainforests across South America, Central America, Africa, Southeast Asia and Australia (and nearby islands).
  • ...6 more annotations...
  • It is almost always raining in a rainforest. Rainforests get over 80 inches (2 m) of rain each year. This is about 1 1/2 inches (3.8 cm) of rain each week. The rain is more evenly distributed throughout the year in a tropical rainforest (even though there is a little seasonality).
    • Luke Whitehouse
       
      Weather conditions and climate.
  • Tropical rainforests cover about 7% of the Earth's surface and are VERY important to the Earth's ecosystem. The rainforests recycle and clean water. Tropical rainforest trees and plants also remove carbon dioxide from the atmosphere and store it in their roots, stems, leaves, and branches. Rainforests affect the greenhouse effect, which traps heat inside the Earth's atmosphere. Some of the foods that were originally from rainforests around the world include cashew nuts, Brazil nuts, Macadamia nuts, bananas, plantains, pineapple, cucumber, cocoa (chocolate), coffee, tea, avocados, papaya, guava, mango, cassava (a starchy root), tapioca, yams, sweet potato, okra, cinnamon, vanilla, nutmeg, mace, ginger, cayenne pepper, cloves, oranges, grapefruit, lemons, limes, passion fruit, peanuts, rice, sugar cane, and coconuts (mostly from coastal areas).

      Importance of the rainforests
  • Once damaged, the soil of a tropical rainforest takes many years to recover.
  • The range of temperature in a tropical rainforest is usually between 75° F and 80° F (24-27° C).
  • The soil of a tropical rainforest is only about 3-4 inches (7.8-10 cm) thick and is ancient.
  • EMERGENTS: Giant trees that are much higher than the average canopy height. It houses many birds and insects. CANOPY: The upper parts of the trees. This leafy environment is full of life in a tropical rainforest and includes: insects, birds, reptiles, mammals, and more. UNDERSTORY: A dark, cool environment under the leaves but over the ground. FOREST FLOOR: Teeming with animal life, especially insects. The largest animals in the rainforest generally live here.

  • 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.

Rainforest Canopy-Animals - 0 views

  • The incredible diversity of food sources and unique niches of the canopy trees support a wide variety of animal species. Animals often congregate around a flowering tree, which makes trees in this stage some of the best sites for viewing wildlife. In places like these, where food is abundant, animals set up territories, but since canopy leaf cover affects visual territorial displays, most animals rely on sound signals. Thus some of the loudest animals of the world are canopy dwellers. Many primates emit howls and screams, while birds use song to let other animals know that they are intruding on their space.

What can you do? - The Royal Society for the Protection of Birds - 0 views

  • Help us save the rainforest animals!Planting more trees and give the animals somewhere to live again. We can buy trees grown by local villagers. That helps people and wildlife at the same time.Perhaps you could ask friends and family to sponsor you to run, walk or cycle. You could organise a cake stall or make and sell homemade greetings cards. Why not sell your old toys that you don’t play with any more?Or maybe you could club together with your class at school, your sports team or your cubs or brownies group and raise money together? You can use the sponsor form on this page.It costs £20 to plant forty trees. Any money that you can raise, from twenty pence to twenty pounds will help save rainforest animals like tigers, gibbons and bears, plus lots of other wildlife.

The Amazon Rainforest - 0 views

      so this is about the rainforest importance
  • The Amazon Rainforest By Alec The Amazon rainforest has many different plants that can be used as herbal medicines. Some of the most important medicines come from the Amazon. They have been used for hundreds and hundreds of years. These plants can be deadly if taken in large doses, but in small doses they can be very helpful. They can be used to cure headaches, skin irritation, high blood pressures, and many other diseases. Here are some of them. White Trillium The white trillium has three petals, three sepals, and three leaves. If the leaves are chewed, it can help cure snake bites. If the plant’s petals are chewed, they can help ease childbirth, and the sepals if chewed are used to help cure fevers. Cinchona Tree (Cinchona officinalis) The bark of this tree is used to make Quinine, a medicine that helps treat Malaria, a serious disease. A number of various other chemicals can also be made from Cinchona, and these chemicals include cinchonine, cinchonidine and quinidine. However, quinine has been replaced by other drugs such as chloroquine and mefloquine, and now quinine is rarely used to treat malaria. Foxglove (Digitalis purpurea) The leaves of this plant contain digitalis, a substance used to treat heart problems. When taken in large doses it can produce palpitations and dizziness, but when taken in smaller doses it can help the heart beat more slowly. This medicine had many effects, and sometimes it cured in miraculous ways, but it mostly produced violent reactions, occasionally killing because it was taken in very large doses. The foxglove tea is used as a morning tea to aid in birth control. Opium Poppy (Papaver somniferum) The opium poppy is used to make Morphine and Codeine, two drugs that are used as painkillers. The opium gum may be crudely refined and smoked, or converted to morphine and heroin.

The CAUSES of RAINFOREST DESTRUCTION - 0 views

  • The creation of national parks has undoubtedly helped to protect rainforests. Yet, as national parks are open to the public, tourism is damaging some of these areas. Often, national parks are advertised to tourists before adequate management plans have been developed and implemented. Inadequate funding is allocated for preservation of forests by government departments. Governments see tourism as an easy way to make money, and therefore tourism is encouraged whilst strict management strategies are given far less government support. Ecotourism, or environmentally friendly tourism, should educate the tourists to be environmentally aware. It should also be of low impact to its environment. Unfortunately, many companies and resorts who advertise themselves as eco-tourist establishments are in fact exploiting the environment for profit. In Cape Tribulation, Australia, for example, the rainforest is being threatened by excessive tourism. Clearing for roads and pollution of waterways are two of the major problems in this area. The Wet Tropics Management Authority which oversees the surrounding World Heritage Area is promoting tourism to the area before any management plans have been formulated, before any effective waste management strategy has been devised and before any ecofriendly power alternatives have been fully explored. Solutions: The rights of indigenous forest dwellers and others who depend on intact forests must be upheld. In instances where there are campaigns opposing specific tourist developments, they should be supported. Genuine ecotourism should be preferred to other tourist enterprises.

      How tourism affects the rainforests.
  •  
    According to Professor Norman Myers, one of the foremost authorities on rates of deforestation in tropical forests, "the annual destruction rate seems set to accelerate yet further, and could well double in another decade" (Myers 1992). As Myers points out, "we still have half of all tropical forests that ever existed". The struggle to save the world's rainforests continues, and there is a growing worldwide concern about the issue. In order to save rainforests, we need to know why they are being destroyed. Nobody knows exactly how much of the world's rainforests have already been destroyed and continue to be razed each year. Data is often imprecise and subject to differing interpretations. However, it is obvious that the area of tropical rainforest is diminishing and the rate of tropical rainforest destruction is escalating worldwide, despite increased environmental activism and awareness. A 1992 study by the Food and Agriculture Organisation (FAO) placed the global rate of tropical deforestation at 17 million ha. per year. A study by the World Resources Institute (WRI) suggests that the figure could be as high as 20.4 million ha. per year. 1. Immediate Causes The immediate causes of rainforest destruction are clear. The main causes of total clearance are agriculture and in drier areas, fuelwood collection. The main cause of forest degradation is logging. Mining, industrial development and large dams also have a serious impact. Tourism is becoming a larger threat to the forests. 1.1 Logging Commercial logging companies cut down mature trees that have been selected for their timber. The timber trade defends itself by saying that this method of 'selective' logging ensures that the forest regrows naturally and in time, is once again ready for their 'safe' logging practices (WWF). In most cases, this is untrue due to the nature of rainforests and of logging practices. Large areas of rainforest are destroyed in order to remove only a few logs. The heavy mac

Taiga Biome - 0 views

  • The taiga or coniferous forest is probably the world's largest land biome. It is located south of the tundra and stretches across portions of North America. Europe and Asia. During the summers, the soil remains very wet and is suitable for lichens and mosses. Fir and spruce trees grow well in this environment. The trees provide homes for many birds including the crossbill, which is capable of cracking cones to eat the seeds. A variety of animals are found in the taiga. They include moose, weasels. wolves, deer. Lynx, caribou, porcupines, beaver, mink and bears.

Conservation - 0 views

  • Why Do We Need To Conserve?One answer is very simple. We need to conserve to make certain we have resources for ourselves and for people in the future. Conservation will allow future generations to enjoy natural resources such as clean rivers and lakes, wilderness areas, a diverse wildlife population, healthy soil, and clean air. Resources Are Necessary for Life! Many natural resources are necessary for our survival. It may be difficult to imagine that we could ever run out of fresh water, clean air, and good soil for growing food. But in some places this is already happening.
  • Using less paper, reusing paper, and recycling paper saves trees and water. Recycling aluminum cans will save money, resources, and prevent pollution. For example, it takes much less energy to recycle an aluminum soft drink can than it does to make a new one. Making energy uses up resources like oil and coal. So just by recycling the aluminum cans you use, you become an instant conservationist!

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.

  • 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.

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

  • Most nonhuman primates live in tropical and subtropical areas of the new world and old world. Most primates live an arboreal lifestyle, that is, they travel, eat, and sleep in the tops of trees. Even the larger apes, like chimpanzees and orangutans, usually sleep in leafy nests they make in trees. The most notable exceptions to this behavior are gorillas and humans. Both are ground dwellers.
  • As primates evolved over the past 50-60 million years, two important things happened. 1) Their faces flattened and the eyes moved to the front of the head, giving them binocular vision. 2) They developed hands with separate fingers and opposable thumbs. This allowed them to grasp and hold on to branches and other objects.

  • Most primate species are omnivores and like to eat many different things including fruit, leaves, insects, larvae, and other animals. Despite being omnivores, most species eat mostly fruit and other plants. Some species, like the orangutans of Borneo, mainly eat fruit. Others, like howler monkeys, eat mostly leaves and have a special digestive system to process them. Scientists think that primates prefer to eat fruit and plants, because it is much easier to get plant foods than hunt for moving animals.
