Environmental protection.


Our earth is our home, so if we want to protect our home we should

protect our environment from harmful effects of human activity. Some of

these activities cause pollution. Pollution now is a very important

problem. Some of these problem are: the ozone holes, global warming ( or

green-house effect), acid rain … The ozone layer is a layer of gases

which stop harmful radiation from the sun protecting the earth. Recent

research shows that there is a hole in part of the ozone layer which is

caused by smoke from factories, car exhaust fumes, aerosol cans ‘cause

they contain CFC. Global warming is an increase in world temperature

caused by an increase in carbon dioxide. Acid rain is rain that contains

dangerous chemicals, this is caused by smoke from factories. Another

problem is poisons in food. Farmer soften spray chemicals in crops to

safe them from pests. These chemicals are called pesticides. Scientists

have found that pesticides often end up in our food and they can cause

health problems - especially for kids. The seas are in danger. They are

filled with poison : industrial, chemical, nuclear waste. Every ten

minutes one kind of animal, plant or insect dies out for ever. And if

nothing is done our earth will die in about 30 years from now. So what

can we do to protect our environment ? I think that we should recycle

our used things, we should plant more trees, we should not waste

resources but try save them, we also must make smoke from factories and

car’s fumes more clean, we must not dump industrial waste to seas and

rivers …Now people are beginning to realize that environmental problems

are not somebody else’s. They make different organization, whose aim is

conservation. For example “GREEN PEACE” , “FRIEND OF THE EARTH” and

others. Everyday millions people from all over the world do everything

to protect our environment , and they need for our help. I think we

ought to help them , just to make our future better.
