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 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 (are cut) or (burnt) to the ground. Will any trees (be left) on our planet at the end of this century? 

Spices diversity of wild animals differs greatly from one region of the world to another one. Almost all the world’s largest animals live in southern countries, where there is enough food and the weather conditions are more or less even throughout the year. For example, the biggest terricole is the African bush elephant, which inhabits vast savannas of this continent. The highest animal in the world is the giraffe, which also lives in Africa. Both the giraffe and the elephant are herbivorous, i.e they eat only plant food. Interestingly, the world’s largest carnivore lives in the Arctic. It is the polar bear, which is considered to be one of the largest, heaviest and the most dangerous wild animals. Its diet consists mostly of fish and small marine animals. And as for the biggest marine mammal, it is, of course, the blue whale. . To my mind, the most unusual wild animals live in Australia. It is, for example, the kangaroo – the most well-know marsupial mammal, which breeds the young in the pouch. It is also a koala bear – a sluggish wooly animal which is often called the symbol of Australia. Finally, Australia is home for the emu, the second largest flightless bird in the world.. As for my homeland, the most famous Russian wild animal is, of course, the bear. Also in vast taiga forests one can meet wolves, foxes, hares, squirrels, wild pigs, roe deer, and so on. Some of them can be rather dangerous, especially in mating season.
