Environmental Problems
1. People have designed and produced up-to-date machines and technologies
to make their life easier and more comfortable. But all these activities result in air
and water pollution.
2. One of the most important problems is the oceans. A lot of ships crossing
the oceans and seas, especially those that carry oil, put their wastes into water, and
the water becomes dirty. As a result many birds and fish die because of polluted
water, others are getting contaminated and people may get sick from eating them.
3. The second problem is air pollution. Cars and plants pollute the
atmosphere with their wastes. They destroy the ozone layer whish protects us from
the dangerous light of the Sun. They also destroy forests which are dying from acid
rains.
The word smog comes from smoke and fog. Smog is a sort of fog with other
substances mixed in it, which can be harmful, even deadly. Such diseases as
eczema and asthma are linked to air pollution.
4. Materials like paper and glass can be reused, but, unfortunately, many
materials, especially plastics cannot be reused and cannot be absorbed by the earth
again. Some plastics cannot even be destroyed. As a result of this people face the
problem of preservation of our environment.
5. Now people begin to realize the danger of their activities. People are
concerned about the air and the water used by everyone, they are also concerned
about the future of the planet because they understand that these activities affect
the balance of nature.
