What else?
• Rainforests are known as
the “lungs of the earth”.
Why?
• Rainforests help convert
carbon dioxide into
oxygen
Tropical Rainforests have very dense
(thick) vegetation; therefore, they
consume a lot of carbon dioxide and
give off a lot of oxygen.
• Rainforests are the home
to the largest variety of
plant and animal species
on the planet

“slash and burn” farming
• Causes a loss of habitat for
species
• Can cause climate change (more
carbon dioxide in the
atmosphere)
• Causes less clean air for humans
• Causes more soil erosion
(trees help keep soil from
eroding)
• Causes soil depletion
(rainforests have rich soil but
when cut down the richness
of the soil is reduced)
• The federal government designated areas
in the Amazon basin for protection,
cracked down on ranchers, farmers and
land speculators, and put pressure on local
governments, while environmentalists
ramped up campaigns against companies
that were exporting beef, leather and soy
beans from illegally cleared land.

Deforestation
• Deforestation rates in Brazil surge, after years of
progress to slow forest loss
• The Rain Forest in Rio's Backyard
• Oil is an important natural
resource in Venezuela
accounting for 50% of the
government’s revenue (income)
• Occasional oil spills have killed
fish, damaging the environment
and fishing industry
• Oil spills have also shut down
tourist resorts
• Contaminated oil pits, which
collect waste from oil wells,
can leak into Venezuela’s
water sources
Burning fossil fuels can cause breathing
problems for children and older adults.
Lake Maracaibo is sinking on the eastern
shore, threatening to flood local towns,
homes, and farms.
An oil spill in
Lake Maracaibo
has prevented
fishermen from
doing their jobs.
