continues.... As trees are cut down, soil is unprotected to the heat of the sun causing it to turn into dust and gradually turn the forest to desert. Also, this has caused the forest to go into extreme drought. Effects:
* Accelerated global warming
*Soil becomes unusable
*Less/Damaged plant life
*Wildfires Food loss The Amazon is very important as a habitat to many species of wildlife. It provides for each species:
By destroying these habitats, it endangers those who can't change quickly to the rapidly changing environment. With the decrease of the tree population, soil isn't able to be anchored down. This means loose soil and widespread erosion that makes it hard for new plant life to take root. Organizations *World Wildlife Fund for Nature (WWF)
*Wildlife Conservation Society
*Friends of the Earth (FOE) Endangered species
Saving wildlife and locations
Keeping the world healthy Pros Cons *Agriculture
*Logging Thank You! *Oxygen production decrease
*Accelerated global warming
When things are weighed in, the cons outnumber the pros greatly. *Cattle ranching
*Infrastructure improvement Sources A lot of damage has been done to the Earth and it is only being made worse with the deforestation of the Amazon Rainforest. As an important asset, it provides many things to support life. As the benefits aren't as plentiful as the damage made, many organizations work to stop deforestation. Economy *Illegal logging causes national economies to lose billions of dollars annually
*Procedures to get amounts of wood cause a lot of harm to the economy. Deforestation rarely makes more than $5 per ton of carbon released and returns less than $1 The UN and the World Bank are working on making programs that help curb deforestation NASA Satellite Pictures 37 years of deforestation is shown (1975-Present) in west Brazil showing the disappearance of the forest. How much of the forest
is lost? *Millions of trees are cut down each year
*Approximately 1 1/2 acres are cut down each second
*Recently, the rate at which deforestation continues at has slowed down
