Our planet is our home. It provides a person with food, heat, resources. It has everything that is necessary for a full life. But human activity is a destructive force that leads to global disturbances of the world. Today, with a naked eye, you can see how nature has changed during the life of a person, since the consequences affect the quality of life of the people themselves , the environment, the animal and plant world.
Why delve into the problem
It is known that in order to solve the problem, you need to understand the root of the problem. This principle is valid and in this case, it is important to prevent pollution of the planet, and not to eliminate the consequences. If there is no source that destroys the environment, our Earth will be able to recover. But in order for the actions to give a result, you should first study how nature has changed over the life of a person and what factors upset the balance of the ecosystem.
Varieties of influence
Human exposure to nature may be deliberate. In this case, in order to meet the needs of society, massive deforestation is carried out , hydraulic structures and other structures are built, or resources are extracted to the detriment of nature.
In addition, harm can be caused unintentionally, for example, the developed places for the extraction of resources are formed into technogenic relief forms, and the processing of resources leads to air pollution.
Also, the natural world suffers from the indirect and direct influence of man. Negative changes (direct impact) occur from irrigation with fertilizers of whole fields in the soil. Broken chains of metabolic processes entail further failures in the ecosystem (indirect).
Bad influence
The impact of human activities on the biosphere is significant, because of this influence our world has become the way we know it today. There are several negative aspects of how nature has changed over the course of a person’s existence:
- Many forest zones have disappeared. The main role of trees is the “fight” with carbon dioxide. Due to this property, trees should soften the climate, but as forests become smaller, the weather around the world has noticeably changed. In addition, the mountain slopes left without trees are doomed to erosion, which leads to collapses.
- The waters of the earth are polluted, its atmosphere, as well as the surrounding nature.
- Soil depletion. To increase the yield of the fields, chemicals and pesticides are used, which take the last useful minerals from the earth. So that the soil can restore the lost balance, it takes tens of years.
- Many species of flora and fauna have disappeared. Human activities have changed the ecosystem, to which some species could not adapt. Others were destroyed by man. Many animals also suffered from the indirect effects of human activities. Thus, the natural world was prone to deforestation due to increased human needs, which is why many species of fauna lost their natural habitat and died.
- Depletion of resources that took millions of years to form. The unprecedented rate of production of coal, oil and other deposits leads to the fact that after 100 years, humanity will be left without these vital minerals.
Bodies of water, oceans
This, of course, is not the entire list of examples of how nature has changed over the course of human existence. Almost all rivers that pass cities are subject to destructive pollution. Also, do not forget about oil, which constantly falls into the water. Just one drop makes 25 liters of water unsuitable, and tons of oil constantly fall into the oceans.
In addition, every year, humanity throws tons of garbage in which plastic predominates. Ultimately, most waste that is not able to decompose into trace elements, find their "rest" in the oceans. Many already know about the "dead zone", which is located in the Pacific Ocean. This is garbage that floats on the surface of the water and occupies a vast territory. Every year, the "dead zone" is replenished with tons of fresh garbage. From the height of the helicopter, this “dump” resembles a large island. Such floating debris does not allow light and air to reach marine life. Some species cannot find a new home and perish.
