  5. The Amazon Basin is over 2 million miles in total area. It is about 40% of Brazil’s land area. • The forests are being destroyed at the rapid pace of human population growth. • Some environmentalist think by 2030, the Amazon will only have 10% remaining and another 10% in degraded condition. • 80 percent of the forest will have been lost and many animals will become endangered http://www.martinfrost.ws/htmlfiles/april2008/deforestation.html
