  • Author: barry a bieda How does the cutting of the rainforest affect Earth? Response #: 1 of 1 Author: mortis Well, we have been cutting rainforests for thousands of years with no permanent damage to the earth at all. Forest people who cut small patches for growing gardens do not hurt the forest because the small plots recover their original growth very quickly: think of the pictures of Mayan ruins in Mexico that are completely covered by forest - these used to be open, active cities! So on a small scale, slash and burn agriculture has no effect whatever on the rain-forest- it is a sustainable use of the forest. However, on a large commercial scale, where bulldozers and flame-throwers are use to convert huge tracts of land into pasture for cattle, the ability of the forest to recover is seriously impaired, destroying the forest for a very long time, if not forever. This kind of unsustainable destructive use affects the earth by taking a large portion of the biosphere out of production - which interrupts the carbon and oxygen cycles, affects local water and soil quality, and causes a decline in the global gene pool by making many species extinct.

    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.

  • 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.

  • n February 2008, Karen Armstrong won the TED Prize and called for the creation of a Charter for Compassion to bring together people of different religions and moral codes in a powerful common cause. The Charter launches November 12, accompanied by thousands of self-organized events, services and sermons. To help prepare the way, today on TED.com we offer six talks from six perspectives. Be ready for a surprise. Compassion is not the soft, fuzzy notion you might expect. Indeed, it might just be the best idea humanity’s ever had.

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.
  • Kavya D on 23 Sep 09
     
    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

  • 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.

  • 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).

      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.

  • 5 Large Dams In India and South America, hundreds of thousands of hectares of forests have been destroyed by the building of hydro-electric dams. It was the dominant view that new dams had to be built or otherwise these countries would suffer an energy crisis. However, a recent study by the World Bank in Brazil has shown that 'sufficient generating capacity already exists to satisfy the expected rise in demand for power over the medium term, provided that the energy is used more efficiently' (WRM). The construction of dams not only destroys the forest but often uproots tens of thousands of people, destroying both their land and their culture. The rates of waterborne diseases increase rapidly. Downstream ecosystems are damaged by dams which trap silt, holding back valuable nutrients. Reduced silt leads to coastal erosion. The sheer weight of water in dams has in Chile, Zimbabwe, and Greece led to earthquakes. The irrigation and industrial projects powered by dams lead to further environmental damage. Irrigation leads to salination of soils and industry leads to pollution. Solutions: Aid organisations like the World Bank have traditionally favoured spectacular large-scale irrigation and hydro-electric projects. In all cases when such projects are proposed, there has been massive opposition from local people. Reform of the World Bank and other such organisations, and support for campaigns against large-scale dams is needed.

  • 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.
