The population of the Earth has exceeded 7 billion. Such a number of people need to feed, dress, shoe, provide a place to stay. And every person has his own interests besides the most urgent needs. And the developed countries in this respect are in the lead. Therefore, the answer to the question of how a person affects nature is unambiguous.
The impact of society on the environment is becoming more and more noticeable every year. There are practically no places on the planet where a person would not reach. In the most unfavorable from the climatic point of view, extraction of minerals takes place. Mankind has become very gluttonous. Now in the course is, probably, the entire periodic table. Many believe that oil is processed, mainly in fuel intended for transport. They are deeply mistaken, the main consumer of oil is the chemical industry.
Virtually all artificial materials are made from oil. Secondary raw materials are used in minimum quantities. And, as you know, oil reserves are by no means infinite. If we add the harm that is caused to nature due to accidents at chemical plants, and they happen regularly, the picture turns out to be bleak.
How does a person influence the nature around him? The vital activity of every living organism always leads to a change in the environment. A simple example: a Colorado beetle destroys a hectare of potatoes. He influenced the amount of harvest, and therefore changed the environment around him. The beetle, of course, is a small creature, it takes a number and an excellent appetite. Possibilities for him are limited. What can not be said about a person, he by nature is given the ability to transform the environment around him....
Anthropogenic influence on nature is also expressed in the huge consumption of fresh water. If we simply consumed it, it would return according to the water cycle in nature, known to every schoolboy. But we pollute it and for the most part, the returned water can no longer be used without further purification. Industrial wastewater and the use of household chemicals remove large volumes of water from the natural cycle.
How does a person affect nature yet? It affects, of course, renewable resources: forests and seas. The number of forests is decreasing every year. And this leads to climate change both in a separate region and on a planetary scale. Because the forest is clean air, regulation of rainfall, the production of a fertile soil layer. The number of forests regulates the flow of air.
Less forests, more open spaces – the speed of air movement increases. Is not this the reason for the increasing number of destructive hurricanes in places where they simply can not be, and the desert sands advance on savannahs? We take a hundred tons of fish from the ocean, half of which simply disappears, while leaving other marine inhabitants without food. Is it possible to say that this is in the order of things?
We know how a person affects nature. Our task is to take all measures to minimize this influence. Every person should ask himself: “What can I do to stop so thoughtlessly exploiting and destroying my own home?”
