Our planet Earth is just a tiny part of the universe, and at the moment it is the only place where people can live.

We have always polluted the environment. But up until now, pollution has not been such a huge problem. People lived in rural areas and could not produce such a huge amount of pollution, which could lead to a dangerous situation on a global scale.
With the development of industrial cities that produce a huge amount of pollutants, the problem became real. Today, our planet is in serious danger. Global warming, acid rain, air and water pollution, overpopulation are problems that threaten the lives of people on Earth.

Every year the world’s industry pollutes the air we breathe. A huge number of cities suffer from smog. Tropical forests are being cut down. Their disappearance violates the oxygen balance. As a result, rare species of animals, birds, fish and plants disappear. Many seas, rivers and lakes are filled with poison: industrial and nuclear waste, chemical fertilizers and pesticides. Air and ocean pollution, destruction of the ozone layer is a consequence of careless human interaction with nature, a sign of an environmental crisis.

People should think over their attitude towards the environment. Some progress has already been made in this direction. Various organizations hold numerous conferences to discuss problems faced by ecologically poor regions, including the Aral Sea, India, China and Chernobyl. Greenpeace is also doing much to protect the environment.

What can we do to save our planet? First of all, people must switch to alternative forms of energy, such as solar energy or wind energy. Secondly, the use of nuclear energy must be banned. Third, we have to recycle. This is the art of turning waste into new products. It would be nice if people started riding bicycles instead of driving cars. We have to protect nature. If everyone cares, it will change the situation.
