Nature
Protection
The Earth is the only planet in our solar system where
there is life. You can see blue rivers, lakes, seas, oceans, green fields and
forests, snowy mountains, many birds and animals. The nature around us is the
environment. Many centuries ago people lived in harmony with nature. But
development of science and technological progress influenced the world.
The
most serious ecological problems are: water pollution, air pollution,
destruction of the ozone layer, acid rain, destruction of tropical forests.
There is no ocean or sea which is not polluted. Many
ships sail in the oceans and pollute them. Factories and plants throw poisonous
industrial waste into water. Some seas and oceans have suffered after nuclear
tests. Many birds and fish die because of the polluted water.
The second important problem is air pollution. Cars,
buses, plants and factories pollute the air we breathe. People in big cities
suffer from noise and smog. Harmful gases destroy the ozone layer which
protects our planet from the dangerous light of the sun.
There are holes in the ozone layer and the sun
radiation gets to the Earth and can cause skin cancer. Burning coal and oil
leads to global warming and changes in the world's climate.
Acid rain contains acid from factory smoke and
destroys trees, rivers and buildings.
One more problem is destruction of tropical forests.
These forests produce oxygen we need. People cut down forests and we have less
oxygen. Many animals and birds disappear, the world's weather is changing.
Many people try to stop pollution and protect nature.
There are some things we can do. We should plant trees and flowers, we mustn't
throw rubbish in the streets and forests. People can recycle things and use
alternative forms of transport and energy.
