CONSEQUENCES OF DEFORESTATION
1. ENVIRONMENTAL DESTRUCTION
2. ANIMAL POPULATIONS DECREASE OR BECOME
EXTINCT
3. INDIGENOUS PEOPLE LOSE THEIR HOMELAND

EXTINCTION OF ANIMAL LIFE
10% OF THE WORLD’S ANIMALS SPECIES ARE ESTIMATED TO LIVE IN AMAZONIA
70% OF THE WORLD’S PLANT AND LAND ANIMALS LIVE IN FORESTS
ON AVERAGE, 137 FORMS OF LIFE NATIVE TO THE TROPICAL RAINFORESTS BECOME EXTINCT EACH DAY

ENVIRONMENTAL CONSEQUENCES
Deforestation ruins soil Without the canopy of
trees, soil becomes dry and infertile
- Fewer trees leads means that more carbon dioxide will be released into the atmosphere and destroy the ozone layer
- Global warming is exacerbated by deforestation
ENVIRONMENTAL CONSEQUENCES CONT.
