We rely on rainforests in ways that we are only just
beginning to understand. We do know that rainforests
play a significant role in maintaining weather
patterns and the Earth's limited supply of fresh
water. We also know that natural elements and species
from the rainforest are the basis of countless
consumer, agricultural, medical, and industrial
products. Although rainforests cover less than 2% of
the Earth's surface, they are home to more than half
of all plant and animal species.
According to The Nature Conservancy, originally, 8
million square miles of tropical rain forest encircled
the planet. More than half has been burned, bulldozed
and obliterated. Now, only 3.4 million square miles
remain. If deforestation continues at current rates,
scientists estimate that nearly all tropical
rainforest ecosystems will be destroyed by the year
2030.
Facts:
* At least 42 million acres of tropical forest are
lost each year, an area the size of Washington State.
* An estimated 50,000 species of plants and animals,
mostly plants and invertebrates and mostly in the
tropics, are condemned to extinction every year, an
average of about 140 a day.
* Since the turn of the century, 90 tribes of
indigenous peoples have been wiped out in Brazil
alone.
* Logging is the principal threat to the tropical
rainforests of Cameroon, Congo and Gabon. It is
estimated that every year 137,000 hectares are logged
in these three countries alone.
* Some reasons that rainforests are being destroyed: for wood [paper] and oil
exploration. However, cattle ranching, mining,road-building, farming, and hydro-electric
dams also threaten the existence of rainforests.
* Rainforests are disappearing at the rate of about
eighty acres every minute
