The fish are dying in the Adirondack lakes in northern New York State. Fishermen are worried. This used to be a favorite spot for sport fishing. But eveiy year there are fewer fish. Some lakes - 6% of them - now have no fish at all. Scientists are beginning to get worried too. What is killing the fish?
The cause of this is acid rain. Acid rain is a kind of air pollution. It is caused by factories that burn coal or oil or gas. These factories send smoke high into the air. The wind often carries the smoke far from the factories. Some of the unhealthy things in the smoke may come down with the rain hundreds of miles away. This is what is happening in the Adirondacks. There are many factories in the midwestern States. They are sending a lot of smoke into the air. The wind blows the smoke towards the east. That means towards New York State and the Adirondack area.
The rain in the Adirondacks is not natural and clean anymore. It is full of acid Chemicals. When it falls in lakes, it changes them too. The lakes become more acidic. Acid water is like vinegar or lemon juice. It hurts when it gets in your eyes. It also kills the plants and animals that usually live in Lake Water. That is why the fish are dying in the Adirondacks.
