What Is an Environment?
All the living things and the characteristics of the area where we live (temperature, humidity, soil, etc)

ENVIRONMENTAL PROBLEMS
POLLUTION DEFORESTATION DESERTIFICATION
EXTINCTION OF ANIMALS HABITAT LOSS

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.

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

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

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.
