Сочинение an essay  на тему экология.Срочноо!

Environmental pollution is one of the most important problem of our time. Nowadays everyone knows what acid rain and greenhouse effect mean. In my country, like everywhere in the world, people have done terrible things that have badly damaged the nature. As a result, today it’s dangerous to eat fish that was caught in the river or mushrooms that were picked in the woods  because they may be contaminated. Not only animals but many plants become extinct. I think the richly varied flora and fauna of our planet is beautiful and we want to preserve it that way. There are also practical reasons for protecting nature. I’m sure that scientists and ecologists in many countries are working on solution of the ecological problems.
