Transcript of Amazon Rainforest Deforestation

Deforestation in the Amazon Rainforest Tropical Rainforests

Located near the equator; very warm

Large amounts of precipitation

Rich ecosystems for many organisms

Produce 40% of earth’s oxygen
Amazon Rainforest Cont'd

About 10% of the world’s known species of animals and plants are found here

Amazon Basin contains 15% of the worlds flowing freshwater

Approximately 30 million people live in the Amazon, including 300 native groups
Amazon Rainforest

Biggest forest in the world

Located in the South American continent

Encompasses 9 countries

3.4 million square miles
Benefits of Rainforests

More than 1 billion people living in extreme poverty depend on forests for water, fuel and livelihoods

50% of pharmaceuticals on the market have an origin in natural products

3.5 million people visited Brazil’s 150 conservation areas between 1991 and 1999
Deforestation is the clearance of naturally occurring forests through methods such as logging and burning. Rainforests are used for timber, fresh water, and for housing and agricultural purposes. Why is the rainforest expoited?

#1 AGRICULTURE

#2 LOGGING

#3 INFRASTRUCTURE PROJECTS

#4 URBANIZATION
AGRICULTURE:

In the 1970s, after the construction of the Trans-Amazonian Highway, the Brazilian government instigated migration of farmers into the rainforest so urban areas don't become over populated. The farmers use the slash and burn technique to make room for agriculture. This burned millions of trees.
--Fertilizer
--Cattle Ranching and Pasture Land LOGGING:

In the 1990s, after the timber stock crashed in China, many of the firms began to move to rainforests all around the world.
--Selective
--Clear-Cut
--Settlements
Infrastructure Projects:

The roads facilitate logging, but they can support just about everything else in the Amazon, such as settlements and mining.
--Transoceanic Highway and Trans-Amazonian Highway
--Private firms

URBANIZATION:

Urban centers can significantly use up resources from the forest in order to expand. Indonesia's massive Transmigration Program moved some 730,000 families—more than six million people—to the outer islands of Irian Jaya, Borneo, Sumatra, and Sulawesi in an effort to reduce population pressures on the crowded central islands of Java and Bali. The program was generally seen as a failure since many colonists failed to establish successful farms in the hinterlands while large areas of primary forest were cleared. Today some of the worst fires in Indonesia occur on these once-forested and now clear-cut lands. Logging, agriculture, and infrastructure development including urbanization all are the main causes of deforestation today. This problem solely exists because of three reasons: people are not educated about this subject, the governments don’t regulate as strictly as they should, and the Amazon is too big to regulate every square inch of. So, we need to: Educate the people, be more developed and less corrupt, and make an efficient use of technology (Remote sensing) so that we can try to keep track of activity inside the forest. The rainforest helps us in:
1) Finding cures for illnesses
2) Oxygen
3) Giving us fresh soil and clean water
4) Preventing fires and floods Help the Amazon
