The protective layer of the Earth, the ozone layer, which protects the Earth from the sun's destructive UV (ultraviolet) rays, is being damaged by CFCs (chlorofluorocarbons). They are released by the daily use of industrial and household products: refrigerators, air conditioners, cleaning chemicals, food packaging. The ozone hole allows more UV rays to penetrate to the Earth. It increases the risk of skin cancer, weakens the immune system of people. Besides, UV rays influence the oceans, the growth of plankton, an essential part of the marine-life food chain in the negative way; reduce economically important crops (rice, cotton, soy beans).
Deforestation could cause one forth of all species on earth to vanish in the next 25 years. These forests in Amazonia, South-East Asia and West and Central Africa are being destroyed at an alarming rate of 42 million acres per year.
The protection of natural resources and wildlife is becoming a political program in every country.
United Nations Environment Program (UNEP) concentrates its activities on these issues.
The 5th of June is proclaimed the World Environmental Day by the UNO and is celebrated every year.
We are obliged to remove factories and plants from cities, use modern technologies, protect and increase the greenery and broaden ecological education. These are the main practical measures, which must be taken in order to improve the ecological situation. Some progress has been already made in this direction.
