Forests - ecosystems or green gold?

The forest is а basis for the existence of many organisms. The forest

protects the Earth from erosion, prevents evaporation ~ in this way it feeds

the rivers and serves home for animals. Forest is not only trees. Under the

branches of higher trees there are lower trees and then - grass, mushrooms,

etc. In this way the density of organisms and its diversity is very high.

Forests are often called 'the lungs of the planet'. As we know, when

man breathes he consumes air containing oxygen and gives out air

containing carbonic gas. So the amount of carbonic gas increases. This

gas is also educed in the process of buming. But there is а way back.

During the photosynthesis carbonic gas tums into oxygen. It's the forests

that do the main part of work tuming СО2 into 0 2• This explains their

name 'the lungs of the planet'.

In his activity man needed timber for building and warming his home

and fields for growing crops. That's why for hundreds of centuries forests

were disappearing and ecological balance was being changed.

For the first civilizations of people it was difficult to realize the possiЬle

danger. Recently the paleontologists found out that ecological crises

happened in ancient times. One of the tribes of the South American lndians

- Anasasi - abruptly left its place of living with roads and irrigation

systems around 1200 AD. lt happened because they had destroyed forests

so violently that the latter didn't replenish on the devastated areas. Similar

proЬlems appeared in the 20th century. The only difference was that

people started thinking the situation over. That's when ecology appeared.

lt's extremely important to take care of forests. If the forest is destroyed

because of commercial interests, there will Ье little water and the erosion

will start on the slopes. Thus, the productivity of planes will decrease.

This shows how important forests are. For the sake of life on the Earth

there must Ье large areas of natural ecosystems.

Our country does much to preserve forests. In 1942 the so-called

'forests of the first group' were created. lt is illegal to cut them. Still, much

depends on the people. Because of them forest fires take place. lt will take

one hundred years to grow the similar forest on the same place. lt's our

task to save natural resources because we are а part of nature, the most

reasonaЬle and responsiЬle part. Only if we take care of the Earth, people

who'll live after us will have а clean planet, fit for healthy living.
