What are Tropical Forests?

Tropical rainforests are a result of constant warm
temperatures and moisture. Tropical forest rainfall averages 90 inches each
year, in comparison to Boise, Idaho, which receives only14 inches annually. In
tropical forests it also does not freeze and the average annual temperature is
at least 75 f. degrees. An area the size of two football
fields of rainforest may contain 42,000 different species of insects, up to 750
types of trees, and 1,500 kinds of plants.
If it were not for humans a dense band of tropical forest
would completely circle the Earth’s equatorial zone. Since the 1900s the
forests have been reduced by half. After World War II the rate of destruction
accelerated. Today about 50 acres per minute are altered, an area the size of
the state of Florida each year. The loss of tropical forests is a serious
threat to wildlife populations. Every year many animals lose their habitat,
including birds of prey. In addition to habitat depletion, tropical forest loss
precipitates erosion and watershed damage as well as long-term ecosystem damage
that is only now beginning to be understood such as forest fragmentation and
loss of biodiversity.
Loss of our tropical forest affects everyone. Use natural
resources wisely!
