Have you ever thought about how a person affects rivers?

The way people influence rivers is well known to ecologists, and they are extremely concerned about the people's careless attitude towards the environment. Constant emissions of waste into rivers and oceans, destruction, contamination of their microflora adversely affect the state of water bodies, as well as the health of the person himself. People use their own hands to pollute rivers with household garbage, waste, chemicals.

The condition of rivers worsens by the mass extermination of fish, crayfish, which are certain filters for water purification. Big damage is done by poachers, placing nets, dynamite checkers for mass catching fish. Rivers have become resource for many factories, as a result of which the rivers dry up, the life of the living creatures floating there.

Without water, a person can not exist, but few people think that by exerting a negative impact on rivers, people destroy their importance, purity and environmental friendliness. Consider, as an example, several rivers, and we will understand how a person affects rivers.

The use of the Inya River

Inya is the right tributary of the Ob. In the valley of the river there are a lot of old men, lake floodplains. Due to the dam the reservoir is based, in which valuable fish breeds, on the coast of the Belovo Sea there is a recreation area. Numerous tributaries flow to Inyu from the foothills, Salair ridge. In the river there are burbot, pike, perch. But nearby coal mining enterprises formed rock dumps, mine development created anthropogenic load on Inyu, and once the most beautiful places turned into dumps with waste, dirty plums. There is a gradual degradation of the river, the formation of a layer of pesticides, heavy metals.

Inja always helped people in growing crops, generating electricity, transporting coal, but today it has to take over the drains of industrial enterprises.

The use of the Neva River

The influence of man on the Neva River began with the construction of a dam on the river and the penetration of the Sea Canal. They began to pass ships and moor almost to the center of the city. A lot of oil spots appeared on the bank of the river, especially in the Leningrad region, there is practically no natural protection. Passing tugs with barges, the ships are gradually waterlogging the banks, the water has long been no longer distinguished by the former cleanliness.

Harming small rivers near Moscow

On the banks of rivers, manure, bird droppings, which appeared after the appearance of complexes and livestock farms, are stored. A difficult situation today is on the right tributary of Istra, the Maglush River . The floodplain is filled with tons of chicken manure, which is not exported from there for years. In the event of a flood, a real ecological catastrophe can occur on the river. Also floodplains of the rivers of Moscow and the region are rendered unusable as a result of plowing of vegetable gardens by summer residents, water pollution by landfills, household waste. The garbage dump is reminiscent of Istria's floodplain, littered with rubbish and riverbeds, which leads to their gradual withering away. Near the rivers trampled grass, shrubs are destroyed. Today, environmentalists "beat all the bells" that it is time to restore the purity of rivers, their flood, otherwise in the near future, natural resources and stocks are threatened with widespread environmental disaster. The influence of man on the river causes irreparable harm to nature.

The situation on the rivers of Crimea

With the increase in production, the influence of man on the natural environment is growing . The water resources of many rivers of the Crimea today, due to the way people influence the rivers, are in a deplorable state. Many quality fish species are on the verge of extinction, instead of them appeared frogs, green algae, which by the absorption of oxygen impede the full vital activity in the water, pollute the water by their decays.

The ecological state of the Crimean rivers is unsatisfactory today. It is urgent to clean reservoirs, ponds, sewage. To do this, it is necessary to reconstruct sewage treatment plants, apply progressive technologies for wastewater treatment, conduct explanatory propaganda among the population, and educational work among children and adolescents.

The use of the Yenisei River

Depletion of the river's water resources occurs constantly. And how does the sewage water of enterprises and communal sewage affect the river? This led to a violation of the balance of the whole ecosystem as a whole, impoverishment of valuable fish stocks. Sinks from the fields contain toxins, the presence of nitrogen and phosphorus in them hits all records with their quantity. Many ducts rot, infection of fish occurs.

Conclusion

There is no doubt in the answer to the question of how a person affects rivers. One can say that it is extremely negative, destroying day after day the flora and fauna of rivers and lakes with their own hands.

With human crime, greed, negligence environmentalists have to fight constantly. Urban water bodies are polluted with garbage, waste, chemicals. Underwater life is gradually being exterminated, this is also facilitated by the presence of many fishermen, poachers, who arrange their networks, dynamite checkers.

Water is the source of life. This expression has long lost its meaning. Nature and rivers become less beautiful, and everything from the harm done by man. Many people know how people influence rivers and lakes. Of course, extremely negative. To struggle with the conservation of resources, their restoration is necessary everywhere, by common efforts, otherwise in the near future rivers and lakes will become completely worthless, and many species of fish will simply disappear.
