Ecological problems should be solved together

Two main problems: lack of water and growth of the world' s population causes the development of the third problem - the problem of pollution. Annually more than 450 billion cubic meters of household and industrial wastes are thrown into the rivers of the world. Many rivers are polluted all the way along their lengths. In the developing countries the unprocessed wastes are thrown into almost every large river. In Russia check-ups of the water showed that 8 out of 10 samples contained dangerously high levels of viruses and bacteria. In the developed countries the wastes are not thrown directly into the rivers and underground waters, but still the water is often polluted by poisons fertilizers. Almost every country having access to an open sea throws unprocessed wastes not far from the seashore, which causes the beaches to be polluted.

Scientists and specialists from various countries, now accompanied by governments and communities have understood that it is not possible to solve ecological problems in one separated country. The developed countries are different from the rest of the world because they use more modern technology and that they have accumulated some knowledge of solving ecological problems. But, living in the same house, is it possible to consider one room as being "clean" while tens of others around it are "dirty". The problems of environmental pollution in general and pollution by solid wastes in particular are "hot" all over the world. Industrial wastes are often thrown without being processed. They may be thrown into rivers or other streams of water, polluting them, or they may be thrown into seas or underground waters. The harm caused by these wastes is non-proportional to their volume. Many of the modern chemical substances have such а strong effect that as а result of leftover pollution large quantities of water become unusable without being specially processed. As а result of using unclean water one-third of the humanity suffers from diseases and has poor health conditions, the other third faces the threat posed by chemicals, thrown into the water, the effects of which can be identified only in the future.
