All mankind understands perfectly well that our planet is under serious threat at present. Each person who lives on the Earth should be involved in an environmental protection. The ozone layer is a special type of oxygen around the Earth. It protects the Earth from ultraviolet radiation which comes from the sun. Aerosol sprays and other chemicals destroy the ozone layer and make a big hole in it. Sun radiation comes to Earth’s atmosphere through this hole and can cause skin cancer. Factories are burning oil, coal and wood and produce carbon dioxide. As a result we’ve got air pollution and people suffer from breathing difficulties. Volcanoes, trees and animals produce natural greenhouse gases. All these have formed a blanket around the Earth which traps the heat of the sun. This is the greenhouse effect. It means the Earth’s climate is changing. The Earth is getting warmer and warmer.There is so much litter around us. People suffer from stomach problems because they drink polluted water and eat fish from contaminated rivers.We should stop over pollution, energy consumption, massive deforestation, acid rains, and global warning. Every 10 minutes one kind of animal, plant or insect dies out forever. Unfortunately, Ukraine faces one more environmental problem, such as nuclear contamination. Chernobyl tragedy which happened in 1986 caused a great damage for nature and people of Ukraine. One-tenth of Ukrainian area was affected by the radiation. The water supply in some areas of our country contains toxic industrial chemicals. Air pollution is also a great environmental problem. The ecosystem of the black Sea is polluted and protected by the state. Let’s do all possible to avoid the complete disaster that is threatening the nature and all of us.
