Transcript of Deforestation
cutting, clearing and removal
of rainforests or related ecosystems. 1. Amazon Basin of South America
2. Congo River Basin of Central Africa
3. S.E Asia
4. New Guinea
5. Madagascar Since the 1600, 90% of the virgin forests that were located in the lower U.S are gone. The rest are public lands. Canada's deforestation rate only accounts for 0.4% of the total global deforestation.
Reforestation: Restocking forests that have depleted due to deforestation.
Afforestation: Establishment of a forest or stand of trees in an area where there was no trees. This creates less bio-diverse ecosystems such as pasture, cropland and plantations. 2. Mining 5.Agriculture: Cash Crops 6. Local, National and International Factors 1. Logging Logging is the cutting, skidding, on-site processing and loading of trees or logs onto trucks or skeleton cars. What is it ? What are the causes of deforestation? The process of extracting minerals or coal from a mine. 3. Oil and Gas Extraction Extracting oil and gases from our earth. 4. Cattle Ranching The practice of grazing livestock such as sheep or cattle for wool or meat. A crop produced for its commercial value not for use by the grower. Development, land titles, government subsidies to attract corporations into developing countries, trade agreements(NAFTA & CAFTA), civil wars, debt, lack of resources and lack of law enforcement.

Rohanie Persaud Deforestation Facts: Did you know that tropical rainforests which cover
6-7% of the earth's surface contain over half of all the
plant and animal species in the world !?
Did you know that 57% of all rainforests remaining are located in the Neotropics with 30% in Brazil ? - > Brazil has the highest annual rate of deforestation today.
- > Atlantic coast of Brazil has lost 90-95% of its rainforests.
- > Central America has 50% of its rainforests.
- > South America has 70% of its rainforests.
- > Philippines has lost 90% of its rainforests!
- > Madagascar has lost 95% of its rainforests!
- > El Salvador has lost 70-85% of its rainforest due to heavy bombing.
-> Sumatra has 15% of its rainforests left.
- > Only 6% of Central Africa's rainforests are protected by law. Statistics on Global Rates of Rainforest Destruction - 2.4 acres per second: equivalent to two U.S football fields.
- 149 acres per minute.
- 214,000 acres per day: an area larger than New York
- 78 million per year: an area larger than Poland.
- On average 137 species become extinct every day; 50,000 a year.
If the current rate of deforestation continues the world's rain forests will vanish within years-causing unknown effects on global climate and eliminating the majority of plant and animal species on the planet. What are the Consequences of Deforestation? Environmental Social Impacts 1.Extinction
4.Changes in Watershed
7. Climate Change
8.Pollution 1.Loss of Culture
2.Displacement of People
4.Conflicts over Race
