OR BECOME EXTINCT
3. INDIGENOUS PEOPLE LOSE THEIR
HOMELAND

ENVIRONMENTAL CONSEQUENCES

Deforestation ruins soil
 Without
the canopy of trees,
soil becomes dry and infertile
ENVIRONMENTAL CONSEQUENCES CONT.
- 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
