In my opinion, people will destroy nature, someday. All trees, fish, and animals will be killed and will vanished, byecause of humans. As a result of air pollution, vandalism, and poaching, all species will disappear. For example, the factory called “Lignums”, pollutes the air with sulphates, sulphites and carbon dioxide. As a result, the river Bullupe is polluted. Fish can’t live in dirty water, so ithey gradually becomes extinct. Moreover, the Siberian tiger, has almost disappeared due to poaching. In 2005, there were 331–393 adult, Amur tigers. Fortunately, this endangered mammal is saved for now, and there is no longer a risk. Furthermore, a thylacine has been living for more than thousand years. The thylacine iwas likely to have become near-extinct, in mainland Australia, about 2000 years ago, and possibly earlier, in New Guinea. However, this animal finally became extinct in 1936, because of our greed. This animal had valuable fur. It was to its advantage and disadvantage at the same time. Another example is the dodo. Like many animals that evolved in isolation, the dodo was entirely fearless of humans.  This fearlessness, and its inability to fly, made the dodo easy prey for sailors. AtIn the end, this animal became extinct, in the XVII century.
