Ecological problems.
Ecology is a science. Many sciences have such prefix.
What does it mean “Eco”?
“ Eco” means “home" in Latin language. It’s a science about our mutual home – about nature.
Science, which teaches us to treat very carefully our homeland.
Environment – is surroundings we live in .
People have always polluted their surroundings . Even in ancient times people admitted that their health was depending on the state of surroundings.
But only in XX century humanity realized , that many diseases are closely connected with the air and water pollution.
From ancient times Nature has served people and been the source of their lives. For thousands of years Man lived in harmony with nature and environment. But due to the development of civilization the man’s tampering (вмешательство) with nature increased.
Many large cities with hundreds of smoky industrial plants and enterprises appear today all over the world. The waste products of their activity pollute the soil we grow plants, the air we need to breath and the water we drink.

- Global warming
Air pollution .
Air pollution is a very serious problem, because polluted air can cause illness and even death. Every year world industry pollutes the atmosphere with about some million tons of dust and other harmful substances.
The destruction of ozone layer and ocean is the result of the man’s careless tampering with nature and the sign of the environmental crisis.
Water pollution.
Water recourses is one of the main factor of existing life in our planet .
First of all water pollution is the result of industrial, agricultural and everyday useless release of wastes into rivers, lakes and seas.
The main part of water pollution plays a large number of oil industry wastes .
Forest destruction.
Forests are cut or burn in fire. And the oxygen balance is caused by their disappearance. As a result rare species of animals, birds, fish and plants disappear forever, a number of rivers and lakes dry up.
Litter pollution.
Litter pollution is the main problem of urban areas where people drop all sorts of packages, pets and cans in the environment , particularly in areas where the law enforcement cannot be applied to them immediately.
If you go out for a picnic or a barbecue, always gather the waste in some plastic bags and dispose ( избавляться) of it properly.
Global warming.
Global warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption (поглощение) of energy radiated from the Earth's surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. Each time we burn oil or even natural gas, more carbon dioxide is added to the atmosphere. The greenhouse effect is what is causing the temperature on the Earth to rise.
Environmental protection is a universal problem. That is why serious measures for creating a system of ecological security should be taken. Some progress has been already made in this direction. About one hundred fifty nine countries — members of the UNO — have organized environmental protection agencies.
Make our home grinner!
The international organization Greenpeace is also trying to do everything to preserve (сохранить) the environment.
Save our planet!
The question about the state of environment should worry everybody. Our health depends on its state. Environment is water that we drink, the air which we breathe. Caring about the world we care about ourselves.
