The Disappearing Rainforests We are losing Earth's greatest biological treasures just as we are beginning to appreciate their true value. Rainforests once covered 14% of the earth's land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years. One and one-half acres of rainforest are lost every second with tragic consequences for both developing and industrial countries. Rainforests are being destroyed because the value of rainforest land is perceived as only the value of its timber by short-sighted governments, multi-national logging companies, and land owners. Nearly half of the world's species of plants, animals and microorganisms will be destroyed or severely threatened over the next quarter century due to rainforest deforestation. Experts estimates that we are losing 137 plant, animal and insect species every single day due to rainforest deforestation.
