Environment is all around us
ENVIRONMENT IS ALL AROUND US
The environment is all around us. It consists of the water, the air and the earth. However,
people don't always care for the environment as they should. Butenvironment is very
important for our health. New civilization gives us many advantages but its products also
pollute and damage the environment where we live in. Pollution affects air, water, land,
forests, people, animals and plants.
One of the biggest problems is air pollution. The air is needful for life - not only for
humans, but also for animals and plants. But it's very polluted, especially in large cities and
in areas with concentrated industrial production, for example in refinery towns. Air quality
is spoiled by eimissions from cars and factories and by burning coal and oil.
The problem is that when we breathe polluted air we are ill much more often. And some
kinds of animals and plants are dying out.
People should try to use alternative sources of energy, such as solar, water or wind. There
are more ways to reduce air pollution caused by road traffic. First of them is to support
public transportation.
But there are still factories that don't pollute only the air, but also the ground andwater. All
organisms need to drink. We cannot survive without wather. And there isless and less
drinkable water on the Earth. It's polluted by waste of chemicals industries, and chemicals
used in agriculture, waste of ships and acid rains.
Acid rain is another point I'd like to speak about. Gases like sulphur dioxide and nitrogen
dioxide are produced by power stations and cars. This gases mixes with water in clouds,
and this makes the acid rain, which damages rivers and trees.
But in some parts of the world trees are not killed by pollution, but by people.Tropical rain
forests are being burnt and cut down because people need more land for agriculture. But
trees are very important for our life because they absorb carbon dioxide from the air and
give out oxygen in return this process called photosynthesis.
When there is too much carbon dioxide in the atmosphere we call it a GREENHOUSE
EFFECT. It caused the global warming because heat come down to Earth and than cannot
escape to space. It is caused by pollution in the air with dangerous gases such as carbon
dioxide. There is a danger of changing weather and rising sea levels as glaciers melts.
Another problem is destroying the ozone layer. The ozone layer is very important, because
it protects us from ultraviolet radiation from the sun. Scientists discovered that there are
holes in it caused by use of some chemicals, ozone damaging gases such as freons use in
aerosols, refrigerators and car air conditionig. UV causes damage to the DNA of cells and
various cancers.

There are some organizations which actively works to protect the environment. The most
famous is Greenpeace, which fights against pollution and the use of nuclear energy in
industry and protects oceans, forests and animals.
HOW TO BE GREEN: But everyone of us can do something to protect the environment.
There is a lot of small things that can help. For example, we should swich off lights, turn
down the central heating, insulate our houses, reduce packaging on goods, re-use items
instead of buying new, and recycle to reduce waste. We also should use unleaded petrol,
public transport or bicycle, take showers instead of baths, don't waste water or electricity
or grow plants and trees.
There are many other things we could do better. We must think of future generations.
