The atmosphere
and oceans are not the only parts of the environment that human
activity (is damaging) day after day. Rainforests (are disappearing) as well,
and their survival (is) questionable today. At the end of the 20th
century E.O.Wilson, a biologist at Harvard, (called) the reducing of
rainforest areas “the greatest extinction since the end of the age of
dinosaurs”. Unlike some environment issues, the reduction of rainforests
(has already received) significant public and media attention. Despite
the movements against chopping down rain forests, the problem (still continues). Every year Brazil (chops) down an area of forest equal to
the size of the state of Nebraska. Rainforests that (were) great some
years ago, (are lost) now. In addition to the Amazon’s rainforests, many
other forests (are cut) down every year as well. According to some
estimates, 50 million acreas of forests (are cut) down every year. The
World Wildlife Fund (says) that every minute 25 to 50 acreas (is cut)
or (burnt) to the ground. Will any trees (be left) on our planet at
the end of this century?
