Environment

Alternative energy:

Most of the energy we use today comes from coal, oil and gas. But these will mot last for ever, and burning them is slowly harming at the atmosphere. We need to look for other ways to supplying energy.

Solar power is a way of using the sun's energy as heat or to make electricity. We can also use wind power by building modern windmills that spin the wind. There are several types of water-power: river water in mountains areas can be used to generate hydroelectric power and we can also create electricity from sea water flowing in and out with tides.

Recycling is the procession of used objects and materials so they can be used again. About 60 per cent of rubbish from homes and factories contain materials that could be recycled. Recycling save energy and raw materials, and also reduce damage to the countryside. Glass, paper and aluminium cans can be recycled very easily. Many towns have bottle banks where people can leave their empty bottles and cans for recycling. A lot of paper bags, writing paper and greetings cards are now produces on recycled paper.

If we want to survive men in the future, we should save water, energy... We should support products that do not contaminate our environment like car converters (katalyzátory), recyclable products.

We should be less wasteful with everything: paper, food, plastic, metal, glass. We should reduce, recycle, reuse things.

The Earth population has reached more than 5 thousand million people and is growing by 200 000 people every day. The Earth's environment cannot long support such a rapid growth. At least but not the last: if we want to save the environment, we have to keep peace on Earth.
