Environmentalists are well aware of how humans affect rivers, and they are extremely concerned about people's careless attitude towards the environment. The constant discharge of waste into rivers and oceans, the destruction and pollution of their microflora adversely affect the state of water bodies, as well as the he alth of the person himself. People pollute the rivers with their own hands with household garbage, waste, chemicals.
The state of the rivers is deteriorating due to the mass extermination of fish, crayfish, which are some kind of filters for water purification. Poachers cause great damage by setting up nets and sticks of dynamite for mass catching fish. The rivers have become a resource for many plants, factories, resulting in the drying up of the rivers, the death of living creatures floating there.
Without water, a person cannot exist, but few people think that, having a negative impact on rivers, people destroy their significance, purity and environmental friendliness with their own hands. Let's take several rivers as an example, and see how a person affects the rivers.
Using the Inya River
Inya is a right tributary of the Ob. There are many oxbow lakes and lake floodplains in the river valley. Due to the dam, a reservoir was founded, inwhere valuable species of fish are bred, there is a recreation area on the shore of the Belovskoye Sea. Numerous tributaries flow into Inya from the foothills, the Salair Ridge. Burbots, pike, perches are found in the river. But the nearby coal-mining enterprises formed rock dumps, the mine working created an anthropogenic load on Inya, and the once 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.
Inya has always helped people grow crops, generate electricity, transport coal, but today she has to take on industrial wastewater.
Use of the Neva River
Human influence on the Neva River began with the construction of a dam on the river and the digging of the Sea Canal. Vessels began to pass and moor almost to the center of the city. Many oil stains have appeared on the river bank, especially in the Leningrad region, and there is practically no natural protection. Passing tugboats with barges, ships are gradually swamping the shores, the water has not been distinguished by experienced purity for a long time.
Harming small rivers near Moscow
Dung, bird droppings, which appeared after the appearance of complexes and livestock farms, is stored along the river banks. The difficult situation today is on the right tributary of the Istra, the Maglusha River. The floodplain is filled with tons of chicken manure, which has not been removed from there for years. In the event of a flood on the river, a real environmental disaster can occur. Also, the floodplains of the rivers of Moscow and the regionfall into disrepair as a result of plowing gardens by summer residents, water pollution by landfills, household waste. The floodplain of Istria resembles a rubbish dump, riverbeds are littered with garbage, which leads to their gradual death. Near the rivers, the herbage is trampled down, shrubs are destroyed. Today, ecologists are "sounding all the bells" that the time has come to restore the purity of rivers, their floods, otherwise, in the near future, natural resources and reserves are threatened with a widespread ecological catastrophe. Human influence 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 Crimea today, due to the way people influence the rivers, are in a deplorable state. Many high-quality fish species are on the verge of extinction, instead of them frogs, green algae appeared, which, by absorbing oxygen, prevent full-fledged life in the water, pollute the water with their decays.
The ecological state of the Crimean rivers today is unsatisfactory. We urgently need to clean reservoirs, ponds, wastewater. To do this, it is necessary to reconstruct treatment facilities, apply advanced wastewater treatment technologies, carry out explanatory propaganda among the population, and educational work among children and adolescents.
Use of the Yenisei River
The river's water resources are depleted all the time. And how do industrial wastewater and municipal wastewater affect the river? This led toimbalance of the entire ecosystem as a whole, depletion of valuable fish stocks. Drainage from the fields contains toxins, the presence of nitrogen and phosphorus in them beats all records with its quantity. Many ducts rot, fish become infected.
Conclusion
There is no doubt about the answer to the question of how humans affect rivers. We can say that it is extremely negative, destroying the flora and fauna of rivers and lakes day after day with their own hands.
With human crime, greed, negligence, environmentalists have to fight constantly. City 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 set up their nets, sticks of dynamite.
Water is the source of life. This expression has long lost its meaning. Nature and rivers become less beautiful, and all from the harm caused by man. Many people know how a person affects rivers and lakes. Of course, it is extremely negative. It is necessary to fight with the conservation of resources, their restoration everywhere, by common efforts, otherwise in the near future rivers and lakes will become completely useless, and many species of fish will simply disappear.
