Since ancient times Nature has served Man being the source of his life. For thousands of years people lived in harmony with environment. But with the development of civilization man's interference in nature began to increase.

An Apple as the World

Look at the apple and use your imagination to think of what the apple could represent. We think it looks like the Earth. Let’s cut the apple into quarters. Three-quarters of the Earth's surface is water and only one-quarter is land.

Let’s cut the piece representing land in half. Only one-half the land, or 0.125 the total Earth's surface is habitable. The rest of the land is the deserts, mountains, frozen ice caps, and other places people cannot live.

We take the piece that represents the habitable land, and cut it into 4 sections. Only 0.25 of the Earth's habitable land or one-thirty-second is where All the Earth's food come from.

Let’s think what would happen if this part of the world were damaged or destroyed.

The ecological harmony is disturbed. Industrial enterprises emit harmful substances causing acid rains, greenhouse effect, ozone depletion. They pollute the air we breath, the water we drink, the land we live in.
