THE CAR OF THE FUTURE

At the present rate of production, oil supplies will run out in about fifty years, and we will have to look for other sources of energy. That is one of the most important aspects of the problem, another being the damage that exhaust fumes do to the environment and health, especially in the towns.

What kind of vehicle will eventually take over? At present there is a lot of talk about electric cars, for they have the advantage of giving off no exhaust fumes. The electric car has a long history. The first cars were built at the end of last century, but they could not compete against the internal combustion engine.

They have several disadvantages. Firstly, we have no really suitable batteries — they tend to be too heavy, take a long time to change, have too small a capacity and a relatively short life.

An electric car can run 200-250 km on one charge while the conventional car which can do about 400 km on a full tank.

POLLUTION

People have designed and produced up-to-date machines and technology to make their life easier and more comfortable. But all these activities result in air and water pollution.

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.

The second problem is air pollution. Cars and plants pollute the atmosphere with their wastes. They destroy the ozone layer which protects us from the UV-rays of the Sun. They also destroy forests which are dying from acid rains.

Now people are beginning to realise 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.

In order to make our life not only easier but better and healthier we must learn to protect the water, the air and the earth from pollution. Our planet belongs to our children and if we want our children to live in a healthier world we must do everything to protect them from the catastrophe.
