Every year more and more plants and animals disappear never to be seen again.

     1    

Every day, thousands of species of animals draw closer to extinction. There are countless numbers of species which may become extinct before they are even discovered.

    2    

The problem is acid rain. Acid rain. Acid rain is a kind of air pollution.

    3    

The rain in many places isn’t natural and clean any more. It’s full of acid chemicals.     4    

But dead fish may be just the beginning of the problem. Scientists are finding other effects of acid rain.

     5    

Now scientists are also beginning to study the effects of acid rain on larger animals. For example, they believe that some deer in Poland are less healthy because of acid rain.

F．In many lakes the fish are dying. Fishermen are worried because every year there are fewer fish and some lakes have no fish at all. Scientists are beginning to get worried too. What is killing
