Causes and Effects Worksheet: The Rainforest

by Julie Wallace, ADMC

Rainforest destruction is now recognized as one of the greatest environmental tragedies of all time. By why are the rainforests disappearing so quickly ?

  • In 1800, there were 2.9 billion hectares of tropical forest worldwide. There are 1.5 billion hectares of tropical forest remaining.

  • Almost 65% of Central America has been cleared to create pastureland for grazing cattle

  • Rainforest land cleared for pasture or farming degrades quickly and is usually abandoned.

  • At least 42 million acres of tropical forest are lost each year, approximately 100 acres/minute.

  • Between 1960-1990, 445 million hectares of tropical forest were cleared.

  • We lose 50 species every day - 2 species per hour - due to tropical deforestation.
