The CAUSES of RAINFOREST DESTRUCTION. 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. Why are rainforests being destroyed? Humans are the main cause of rainforest destruction.
We are cutting down rainforests for many reasons, including: In 2005 and 2010 the Amazon experienced the worst droughts ever recorded. Rivers dried up, isolating communities, and millions of acres burned. The smoke caused widespread health problems, interfered with transportation, and blocked the formation of rain clouds, while the burning contributed huge amounts of carbon dioxide to the atmosphere, worsening the effects of climate change. Meanwhile, Indonesia has experienced several severe droughts in recent decades. ** The vast majority of scientists believe that human activities are contributing to climate change. By Rhett Butler.
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. 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. 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. 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. 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. Endangered Animals List. 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.
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.
“Homesteader” policies also encourage citizens to clear-cut forests for farms. Threats Solutions. Rainforest Concern - What can we do to stop deforestation? There are lots of other things you can do that will make a difference to the world’s rainforests, as well as your local environment.
Below are listed a few of them: click on a heading to find out more. You will be surprised how your choices in a local shop or supermarket can affect forests half way across the world! And remember that it is just as important to look after your local wildlife and environment as it is to save rainforests. Try to persuade your family and friends to join in too! Next time you buy a hamburger from a big fast food chain, think about where the meat has come from... Travelling.
