Nowadays, the environmentalists are so worried about environmental problems that can directly affect people’s life. Among the problems mentioned every day in mass media, air pollution and water pollution are considered the most serious ones.
There are many factors that cause the pollution of the air: chemicals from burned fuels, smoke from automobiles, and acid rain from chemical transformation. Smoke can cause serious health problems while acid rain is responsible for the destruction of many forest ecosystems.
Raw sewage, garbage, and oil contribute to the pollution of water. When water is polluted, it causes a lot of waterborne diseases and threatens marine wildlife. About 1.5 billion people around the world lack safe drinking water and every year 5 million people die from diseases.
