How does a person influence nature?

After the appearance of man on earth, nature began to change. Human impact on nature can be negative and positive. First of all, with the invention of modern technologies, the construction of factories, cars and everything that humanity needs for a comfortable existence, we began to forget about nature. After all, chemicals that are emitted by factories, gases and large-scale construction are destroying our nature. Forests are gradually depleted, many species of animals and plants are dying out. But man also brings positive aspects to the life of nature. There are massive campaigns for landscaping, for the protection of animals and plants, for the purification of reservoirs.
