The impact of a person on the environment and what is eutrophication?

The effect of man on the environment

Taking advantage of the benefits of the environment, people gradually contribute to her depletion and destruction. Actions taken by them have a huge effect on the deterioration in the purity of air, water and soil and reduce the biological diversity of living organisms.
Technogenic actions that have a negative impact on the environment (direct or indirect):
• industrial development;
• communication development;
• construction of residential arrays and roads (land and water);
• development of agriculture;
• deforestation;
• Excessive exploitation of natural resources (fossil fuel, metal ores, mining raw materials);
• Excessive exploitation of wild plants and animals (including poaching, reckless hunting and fisheries, gathering protected plants, exotic animal trading);
• destruction or change in the natural habitat;
Human activity that has a favorable environmental impact (direct or indirect):
• introduction of legal norms;
• Environmental awareness activities (education in schools and the media);
• creation of protected areas (national parks, landscape parks, reserves, etc.);
• Protection of species;
Eutrophication - what it is, consequences, prevention
What is eutrophication?
The process leading to an increase in water fertility. It consists in adding biogenic elements in the reservoirs, mainly phosphorus. This is caused by an increase in the amount of pollutants falling into the mouth of the sewage, and then in the reservoirs. The most common pollutants: chemicals, detergents. On the other hand, nitrogen - fertilizer components - falls directly in reservoirs from agricultural land, washed with rain.
What are the environmental consequences of increased eutrophication?
When the nutrient content in the reservoirs exceeds the permissible limits, phytoplankton's organisms significantly increase, which causes the appearance of flowering. The number of cyanobacteria producing toxins increases, harm the fauna in water.
The strong growth of plants near the shore limits the access of light to plants in deeper layers of water, which leads to a slowdown in their growth. Aquatic animals are also subjected to limited access to oxygen, which, in turn, leads to a reduction in the number of individuals, which is often especially important for the preservation of biodiversity.
How to prevent excessive eutrophication?
Used and efficient method - using the disk of the sect. It is white, and, depending on the visibility of this disk, the Carlson index is calculated, which allows you to estimate changes in the suspension in water for a certain period of time. The most important method of combating excessive eutrophication is the selection of materials discharged into the sewer.
