Immediate Causes Logging Agriculture-Shifted Cultivators Agricultures-Cash Crops & Cattle Ranching Fuelwood Large Dams Mining and Industry Colonisation Schemes Tourism 2. Underlying Causes Development and Overconsumtion: the Basis Cause Colonialism Exploitation by Industrialised Countries The Debt Burden The Role of Poverty and Overpopulation 3. For more on the causes of rainforest destruction, link to World Rainforest Movement "Deforestation, in other words, is an expression of social injustice " - Marcus Colchester 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).
We can stop using tropical timber and urge others to do the same. Why are rainforests being destroyed? Saving the Rainforest. How Humans Affect Animals. There are millions of insects, fish, amphibians, reptiles, birds and mammals, but only one kind of human. Human can do good things for animals: help save endangered species by breeding more animals and saving their environment; making sick animals healthy, and caring for animals who can no longer live in the wild. Humans can also cause harm to animals, on purpose or by accident.
Habitat Destruction When humans destroy wild land to build homes, factories, shopping malls, amusement parks, garbage dumps, even to build a visitor center, store and restaurant in a park, the land is changed. The animals that once lived there, from the bugs that lived in the ground to the birds that ate them, all may disappear. Some can move to new home areas, but there are already other animals living there. When farmers spray chemicals on their crops to save them from pests (bugs and molds and things that eat the plants), the chemicals get into the water and into the soil.
What can YOU do? Don’t dump! Rainforest Destruction. What can you do to help save the rainforest? Use less paper to help save the rainforest! Paper is made from trees. If you use less paper, fewer trees will be cut down. Using less paper is easy. Use less gasoline and plastic. Gasoline and plastic are two things that are made from oil. Instead of using gasoline to drive somewhere in a car, ride your bike, walk, carpool, or take the bus whenever possible. Instead of buying plastic, choose glass containers whenever possible.
Eat less red meat. Rain Forest -- National Geographic. In Brazil, which houses 30 percent of the remaining tropical rain forest on Earth, more than 50,000 square miles of rain forest were lost to deforestation between 2000 and 2005. Biologists worry about the long-term consequences. Drought may be one. Some rain forests, including the Amazon, began experiencing drought in the 1990s, possibly due to deforestation and global warming. Efforts to discourage deforestation, mainly through sustainable-logging initiatives, are underway on a very limited basis but have had a negligible impact so far. The rain forest is nearly self-watering. Plants in the rain forest grow very close together and contend with the constant threat of insect predators.
The National Cancer Institute (NCI) estimates that 70 percent of the anti-cancer plants identified so far are rain forest plants. Many trees and plants, like orchids, have been removed from the rain forest and cultivated. Forests: Threats to our forests. Deforestation Results of deforestation Forests are cleared all around the world for a number of reasons, including: Harvesting of timber to produce wood and paper products Clearing land for farms, cash-crop plantations, and cattle ranching Clearing land for urban development, including homes and roads. Forests are also being destroyed by acid rain resulting from our pollution-causing activities and through the introduction of disease and invasive species. Deforestation is a very real environmental threat. Our once vast forests are disappearing. All around the world, trees are being cut down too quickly for earth to regenerate new forests.
What happens when forests are cleared? Floods and soil erosion Erosion The roots of a tree make gaps in the soil so that when it rains the water can sink in before being absorbed by the soil. Because the soil no longer can absorb the water, when it rains the water remains on the top of the soil and this can result in floods. Drought Species extinction. Deforestation. Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use. Deforestation occurs for many reasons: trees are cut down to be used or sold as fuel (sometimes in the form of charcoal) or timber, while cleared land is used as pasture for livestock, plantations of commodities and settlements. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity.
It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforestation has also been used in war to deprive the enemy of cover for its forces and also vital resources. Disregard of ascribed value, lax forest management and deficient environmental laws are some of the factors that allow deforestation to occur on a large scale. Causes Environmental problems Atmospheric Hydrological Soil Biodiversity. Endangered Animals List. Animal endangerment is a big environmental issue, and the number of endangered animals is constantly on the rise. See the IUCN definitions of different types of animal endangerment here. Below is a list of some of the most popular endangered animals, according to the IUCN classification.
Critically Endangered Animals Sumatran Orangutan (Indonesia) Sumatran Tiger (Indonesia) Lear’s Macaw (Brazil) Brown Spider Monkey (Colombia, Venezuela) Rancho Grande Harlequin Frog (Venezuela) Panamanian Golden Frog (Panama) Pygmy Three-toed Sloth (Panama) Yellow-crested Cockatoo (Indonesia) Golden-bellied Capuchin (Brazil) Elegant Frog (Australia) Orinoco Crocodile (Colombia, Venezuela) Mountain Gorilla (Rwanda, Uganda, Democratic Republic of Congo) Golden Mantella (Madagascar) Eastern Red Colobus (Kenya) Javan Rhinoceros (Indonesia, Vietnam) Endangered Animals Vulnerable Animals Blue Poison Frog (Suriname) Giant Armadillo (South America) Near Threatened Animals.
Deforestation Facts, Deforestation Information, Effects of Deforestation. Modern-Day Plague Deforestation is clearing Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world’s land area, but swaths the size of Panama are lost each and every year. The world’s rain forests could completely vanish in a hundred years at the current rate of deforestation. Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families.The biggest driver of deforestation is agriculture. Logging operations, which provide the world’s wood and paper products, also cut countless trees each year. Not all deforestation is intentional. Deforestation has many negative effects on the environment. Deforestation also drives climate change. Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day and holds in heat at night.
Rain Forest Threats, Rain Forest Species. More than half of Earth’s rain forests have already been lost forever to the insatiable human demand for wood and arable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent. And if current deforestation rates continue, these critical habitats could disappear from the planet completely within the next hundred years. The reasons for plundering rain forests are mainly economic. Wealthy nations drive demand for tropical timber, and cash-strapped governments often grant logging concessions at a fraction of the land’s true value. Threats Solutions. Rainforest Concern - What can we do to stop deforestation?

Environmental issue. Environmental issues are harmful effects of human activitity on the biophysical environment. Environmentalism, a social and environmental movement, addresses environmental issues through advocacy, education and activism. The carbon dioxide equivalent of greenhouse gases (GHG) in the atmosphere has already exceeded 400 parts per million (NOAA) (with total "long-term" GHG exceeding 455 parts per million). (Intergovernmental Panel on Climate Change Report) This level is considered a tipping point. "The amount of greenhouse gas in the atmosphere is already above the threshold that can potentially cause dangerous climate change.
We are already at risk...It's not next year or next decade, it's now. " Report from the UN Office for the Coordination of Humanitarian Affairs (OCHA): "Climate disasters are on the rise. Types Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion etc. Scientific grounding Solutions
