What do people do to protect rivers from the harmful effects of human activity?
Water resources are a very important strategic reserve of any country. Water is of great natural value. The quality of water sources, their composition depends on the state of the environment in general, as well as the health of people in particular.
Water is life. Therefore, it is extremely important to preserve this resource and use it rationally. What do people do to protect rivers? These and other questions we will consider in this article.
What and how pollute the river
Due to the increased anthropogenic load on all elements of the biosphere, the main problem nowadays is the pollution of rivers with harmful substances emitted by industrial enterprises. As a result of the discharge of sewage, the composition of the water is changing for the worse; animals and plants living in water bodies are dying. Harmful substances enter the rivers also from farmland - these are various chemicals and fertilizers.Irrigation, water intake on livestock farms - all this harms water resources, disrupting the natural hydrological regime.
As we can see, human impact on the entire ecosystem, including water reserves, is quite large. Therefore, for the protection of water resources and the environment it is necessary to carry out various activities. How much a given resource can be maintained depends on what people do to protect rivers.
The problem of river siltation
Along with the anthropogenic influence on the rivers, which consists in water pollution by harmful chemicals, there is also the problem of siltation. It contributes to raising the level of groundwater, as well as waterlogging of floodplains This makes them unsuitable for use.
This problem concerns small rivers. Its consequences are very great and destructive. During the spring flood, the probability of flooding of settlements located along the riverbed increases. River siltation can lead to disastrous results, disrupting the entire ecosystem. The process of desertification may begin, the composition of vegetation may change, some types of trees and shrubs may disappear completely.
Contamination of rivers with oil products
This is one of the most acute problems. This kind of pollution tends to spread over very large areas. Getting into the natural environment, petroleum products violate the processes of photosynthesis, as well as hydrocarbon and oxygen exchange. The impact of these substances is detrimental to the development of natural biocenoses. As a result of oil pollution of rivers, a high probability of death of entire links of the natural ecosystem is high.
What do people do to protect rivers from oil products? The complexity of the problem is that special studies in this area are very expensive, as well as localization and liquidation of the consequences of the ingress of petroleum products into the environment. Therefore, it is better to prevent these harmful substances from entering the ecosystem than to eliminate the consequences. It is necessary to work hard in this direction so that emergency discharges do not damage the ecology.
What do people do to protect rivers
A number of activities are being carried out in this direction. The use and protection of rivers is an important task that people face, because the life and health of all living things depend on it.
The main methods of river protection:
- Purification of industrial and household waste.
- Introduction of water saving technologies.
- Strengthen monitoring of compliance with standards for the discharge of harmful substances into rivers.
- Cleaning of the rivers and lakes from municipal solid waste.
- Restriction of discharge of untreated sewage into water bodies.
- Tightening control over cattle grazing in floodplains.
- Preventing chemicals and fertilizers from fields from entering water bodies. The same applies to fecal masses.
- Planting of greenery along the river beds.
An important link in the chain of environmental measures is the monitoring of the state of water bodies. This is necessary in order to know the real picture and take concrete decisions accordingly.
The rational use of water resources and the protection of rivers from pollution is the task of each of us. There are events that are held at the highest level, decisions made by the authorities. But on the ground, each of us can influence the ecological situation of our region. From school years, children should learn to take care of nature. Do not dispose of garbage, do not pollute the environment.This applies to water, and to the soil, and to green spaces. In our power to make your home cleaner and healthier.
