3. The environment
The environment means surroundings in which people, animals and plants develop and exist.

4. Environmental problems now:
The air pollution
The water pollution
The ground pollution

5. Air pollution
If you hear the word „environmental pollution” you think of factories, plants, cars and buses.
The growing number of cars on roads and highways contribute much to the air pollution.
Factories produce large quantities of carbon dioxide, radioactive particles, sulphur and nitrogen, which get into the air.

6. Water pollution
Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans and groundwater).
Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.

7. Protection for the environment
I think that the best way how to reduce pollution, is reusing and recycling.
People should make and buy environmental goods, solve the problem of the selective garbage collection system and recycling, save the air, the waters, the woods, and bring up environment-minded children. I think most of us want to live in a peaceful and unpolluted World.

8. Greenhouse effect
In the last 100 years the Earth’s surface has warmed up by more than half a degree, this change could cause rising the sea levels by up to one and half meters by the year 2030.
The Greenhouse effect is caused by polluted atmosphere which was polluted by carbon dioxide.

9. Ozone Hole
The ozone hole is thinning at a rapid speed. It is a layer which protect us from dangerous UV rays, these could damage the life on the Earth.

10. Acid rain What is acid rain?
Acid rain is caused by emissions of sulphur dioxide and nitrogen oxides.
