Ecologists are well aware of how people influence rivers, and they are extremely concerned about people’s careless attitude to the environment. Constant waste emissions into rivers and oceans, destruction, pollution of their microflora adversely affect the state of water bodies, as well as the health of man himself. Do-it-yourself people pollute rivers with household garbage, waste, and chemicals.
The condition of the rivers is deteriorating by the mass extermination of fish, crayfish, which are some filters for water purification. Poachers do a lot of damage by arranging nets and dynamite checkers for mass fishing. Rivers have become resourceful for many factories, factories, as a result of which the rivers dry up, the death of living creatures there.
Without water, a person cannot exist, but few people think that by exerting a negative influence on rivers, people destroy their importance, purity and environmental friendliness with their own hands. Consider several rivers as an example, and see how a person affects rivers.
Using the Inya River
Inya is the right tributary of the Ob. In the river valley there are many old women, lake floodplains. Due to the dam, a reservoir was established in which valuable fish species are bred; a recreation area is located on the shore of the Belovsky Sea. Numerous tributaries flock to the Inuya from the foothills of the Salair Ridge. In the river there are burbots, pike, perches. But nearby coal mining enterprises formed rock dumps, mine work created an anthropogenic load on Yin, and once the most beautiful places turned into landfills with waste, dirty plums. There is a gradual degradation of the river, the formation of a layer of pesticides, heavy metals.
Inya has always helped people in growing crops, generating electricity, transporting coal, but today she has to take over the effluents of industrial enterprises.
Use of the Neva River
The human influence on the Neva River began with the construction of a dam on the river and the digging of the Sea Canal. Ships began to pass and moor almost to the center of the city. A lot of oil spots appeared on the banks of the river, especially in the Leningrad Region; there is practically no natural protection. Passing tugboats with barges, ships are gradually swamping the shores, the water has long been not distinguished by its experienced purity.
Damage to small rivers near Moscow
On the banks of the rivers manure is stored, bird droppings that appeared after the appearance of complexes and livestock farms. The difficult situation today is on the right tributary of Istra, the river Maglush. The floodplain is filled with tons of chicken manure, which has not been exported from there for years. In the event of a flood on the river, a real environmental disaster can occur. Also, floodplains of the rivers of Moscow and the region become unusable as a result of plowing of vegetable gardens by summer residents, water pollution by dumps, household waste. The landfill is reminiscent of the Istrian floodplain, littered with garbage and river beds, which leads to their gradual withering away. Near the rivers trampled grass, destroyed shrubs. Today, ecologists are sounding the bell that the time has come to restore the purity of the rivers and their flood, otherwise in the near future natural resources and reserves are facing a widespread environmental catastrophe. Human influence on the river causes irreparable harm to nature.
The situation on the rivers of Crimea
With an increase in production, the human influence on the natural environment grows . Water resources of many rivers of Crimea today, due to how a person affects the rivers, are in a deplorable state. Many high-quality fish species are on the verge of extinction, instead of them there are frogs, green algae, which, by the absorption of oxygen, impede the full functioning of water, pollute the water with their decays.
The ecological condition of the rivers of Crimea today is unsatisfactory. Urgently need to clean reservoirs, ponds, wastewater. To do this, it is necessary to reconstruct sewage treatment plants, apply advanced technologies for wastewater treatment, conduct explanatory propaganda among the population, educational work among children and adolescents.
Use of the Yenisei River
The depletion of the river’s water resources is ongoing. And how do enterprise effluents and municipal drains affect the river? This led to the imbalance of the entire ecosystem as a whole, and the depletion of stocks of valuable fish. The drains from the fields contain toxins, the presence of nitrogen and phosphorus in them breaks all records with their quantity. Many ducts rot, fish become infected.
Conclusion
There is no doubt about the answer to the question of how a person affects rivers. We can say that it is extremely negative, destroying the flora and fauna of rivers and lakes with their own hands day after day.
Environmental crime has to be constantly fought with human crime, greed, negligence. Urban water bodies are polluted with garbage, waste, chemicals. Underwater life is gradually extinguished, this is also facilitated by the presence of many fishermen, poachers who arrange their nets, dynamite checkers.
Water is the source of life. This expression has long lost its meaning. Nature and rivers become less beautiful, and all from the harm done by man. Many people know how a person affects rivers and lakes. Of course, extremely negative. Fighting the conservation of resources, their restoration must be everywhere, by common efforts, otherwise in the near future the rivers and lakes will become completely worthless, and many species of fish will simply disappear.
