- At least 50 million acres of rain-forest are lost every year, totaling an area the size of England, Wales and Scotland combined. More than 50 percent of all living creatures on the earth reside in tropical rain-forests, so with rain-forest destruction they’re disappearing at a rate of 100 species per day. Experts believe that 5 to 10 percent of tropical rain-forest species will become extinct during the next half-century. They’re also projecting that half of the remaining Amazon rain-forest may be destroyed by the year 2030. The World Wildlife Fund concluded that 55 percent of the world’s largest rain-forest stands to be severely damaged from agriculture, drought, fire, logging and livestock ranching over the next 22 years.
