In recent years the environmental problems have
become extremely urgent and received a great publicity. They are the result of
scientific and technological progress of the 20-th century. But people also do
a lot of harm to nature because they don't understand that the man is the part
of the environment. The relationship between man and nature has become one of
the most vital problems facing civilization today.
The ecological
problems are: air,
water and noise pollution, cutting down forests, animals are used for
scientific researches, hunting rare animals, oil spills, contamination,
ultraviolet radiation, carbon dioxide increase, holes in an ozone layer, forest
fires, sewage, fumes, overfishing, nuclear weapon tests, etc.
Now we face the
following results:
extinction of many species, global warming, shortage of water, acid rains,
deforestation, droughts, floods, etc.
Cars are one of the most harmful and dangerous
polluters of air. In more than a hundred towns and cities the concentration of
harmful substances in the air and water is 10 times over the admissible level.
Besides, we must remember about ozone holes over our heads. The ozone layer
doesn't protect us from dangerous ultraviolet rays any more. They get through the
atmosphere causing skin cancer and other diseases. All these facts make us
become more sensitive towards the environment.
To help the
environment we should
create special zones for animals, make the logging companies plant trees, use
less plastic and paper, reduce carbon dioxide emission, and use less aerosol
spray. There should be a strong public reaction to the problems. It’s necessary
to keep our environment clean and explore nature in the right way.
Various public
organizations and
unofficial movement make their best to change official and public opinion on
the environmental problems. I suppose the solution of the problem requires the
cooperation of the people's efforts in nature conservation.
