ENVIRONMENTAL PROBLEMS

POLLUTION DEFORESTATION DESERTIFICATION

EXTINCTION OF ANIMALS HABITAT LOSS

Page 4: Modern enviorenmental problems

The accumulation of

harmful substances on the

ground, water and air

causes pollution.

Dissapearance of forest,

cutting down of trees,

pollution and fires cause

Desertification.

Page 5: Modern enviorenmental problems

The transformation of some landscapes into desert areas when the soil becomes dry and poor is called desertification

Habitat lossoccurs when natural areas are destroyed to make room for housing or industry.

Excessive development, hunting, fires and other actions cause

extinction of animals.

Air pollution

The air in our towns and cities is very polluted with gases, car fumes, smoke. It is becoming more and more difficult to breathe.

The destruction of the ozone layer

The ozone layer is damaged and it is very dangerous for our planet. The ozone layer is a layer of gases in the sky

that prevents harmful radiation from the sun from reaching the Earth

Page 9: Modern enviorenmental problems

Deforestation

is the cutting down or burning down of all the trees in the area. It means that birds, animals and insects have nowhere to live and become extinct. The amount of oxygen is reduced because trees produce it

Page 11: Modern enviorenmental problems

Many environmental problems are caused byhuman actions. That is why we are responsible forfinding solutions to these problems.

1. Reduce pollution:

reduce the amount of garbage we produce.

2. Avoid cutting down trees: we can plant trees in agricultural areas or substitute wood for other materials.

3. Outlaw the hunting of animals: if animals are in dangerof extinction.

4. Protect specific natual areas: they are importantbecuase of their natural resources. Hunting and cutting treesmust be forbidden.
