Water pollution
Rivers, lakes, seas, oceans cover more than 70 of our planet. Scientists say "man will die if oceans die". Over 5 million tons of oil products pollute the ocean each year. About 2 million tons of these products come from cars. First the oil products go into atmosphere. From the atmosphere they go into oceans. A ship wrecked tankers spill a lot of oil into the ocean. In addition big rivers carry into the ocean a lot of waste from industry and agriculture. Pollution means death to oceans. It kills fish, plants and birds. Experts believe life in oceans will be destroyed within 25 years. The industry affects the nature greatly. For example more than 30 years ago a pulp-and-paper factory was built on the shore of lake Baikal. As a result, because of the water pollution, more than 50 of the worlds purest water has been ruined. The whole ecological system of lake has changed greatly. Some organisms that can be found only in the lake Baikal are disappearing; trees are dying from the dust and gas blow-outs of the factory.
All life on the Earth - from the smallest bug to the biggest whale - depends on the water. Its precious.
