  Our planet is the only place where a human being might live. Unfortunately, scientists haven’t yet discovered other planets, to where a person may move and live the rest of life.

  A human being is able not only to create but also to destroy. Especially our earth suffers badly from pernicious actions of man. This applies to both people’s neglectful attitude to the nature – dropping of cigarette ends, rubbish on the earth – and industrial factories and natural appearances

  Factories regularly emit harmful chemicals into the air. Petrol and gas, that are used by our drivers, also leave much to be desired. Apart from air pollution, water and soil are subjected to pollutions as well. When such fuels as coal and oil burn, they emit very dangerous smoke.

  Water Pollution
  Water covers over 70% of the Earth’s surface. It is very important resource for people and the environment. One of the most urgent problems of today’s life is pollution and especially water pollution. A lot of people can’t drink water from the rivers they live at or use tap water, because most of seas and rivers are used as dumps for industrial and nuclear wastes. These substances are harmful for life beings. This results in water poisoning, which kills fish and sea animals. When animals eat other animals that are already poisoned, the chemicals are passed up through the food chain and become even more harmful. Moreover this poisoned fish can be eaten by people and cause various diseases. Water pollution destroys ecosystems.

  Air Pollution
  Obviously air is essential for every life being on our planet - for people, animals and plants. Without air no life on Earth could exist. But today we face one urgent problem - the industry keeps on developing and it results in air pollution. There are so many factories around that exhaust wastes into the air. If you live in city you have certainly noticed how hard it is to breath sometimes. This happens because of huge amount of cars and their exhausts. In some countries there is even a law that allows families to have only one car to reduce the amount of harmful substances that they throw into the air.

  DEFORESTATION
  Some people’s activities do a lot of harm to the forests. People cut down trees to build houses, roads, factories and plants. Deforestation is a very serious environmental problem. The world’s great rainforest are all near the equator, in Africa, South America and South-East Asia. These rainforests are homes to millions of kinds of exotic animals, birds, reptiles, insects, strange plants and beautiful flowers. Three quarters of the world’s species live in the rainforests. If we destroy their habitat many of them will not survive. Amazon rainforest is the biggest and most important in South America. Scientists believe that plants from the forest could give us many important new medicines such as cures for cancer and AIDS. The rainforests also help to reduce pollution levels in the atmosphere and affect the weather around the world. Without rainforests our planet might not survive.

  Species extinctions
  Species extinctions are occurring at a rate far greater than the natural cycle, owing largely to habitat destruction caused by human activities such as deforestation and land clearance.

  A person destroys not only environment, plants, animals, but also himself. Faster and faster man’s health starts worsening; children of weak immune system are being given birth. Forests are being cut down, and animals from the Red Book are gradually dying out. What will be next in our world of progressive technology remains undecided.
  Let’s protect the nature.
  Nature is our friend!
