Due to low productivity, human strength is particularly weak in the face of climate, weather changes and diseases. Facing nature, human beings feel powerless and blindly worship nature. The transformation of the environment by human beings is very weak, so the environmental problems are not obvious.

2, the transformation of the natural stage

After stepping into the agricultural society, human beings began to carry out the activities of "transforming nature" on an increasingly large scale. With the expansion of cultivated land, human beings have obtained a stable food source. At the same time, the population is increasing rapidly, forests and grasslands are degraded, soil erosion is serious, biological species are decreasing, and many prosperous places that gave birth to human civilization are declining.

3. The stage of conquering nature

/kloc-since the 0/8th century, countries all over the world have successively embarked on the road of industrialization, and science and technology have developed rapidly. Mankind has realized the dream of conquering and dominating nature, and accumulated a great deal of material wealth at the expense of nature. But at the same time, nature began to retaliate against human destruction, and the contradiction between man and land intensified rapidly.

4. The stage of seeking human-land coordination

Mankind was forced to change its "conqueror" attitude, re-examine its own behavior, and gradually realized that man and nature should be interdependent. The concepts of "returning to nature" and "harmony between man and nature" were gradually accepted by human beings, and the issues of environment and development began to receive universal attention from the international community.

Extended data:

There are various environmental problems, which can be classified into two categories:

One is the primary environmental problems caused by natural evolution and natural disasters, also known as primary environmental problems. Such as earthquake, flood, drought, typhoon, collapse, landslide and debris flow.

One is the secondary environmental problem caused by human activities, which is also called secondary environmental problem. Secondary environmental problems are generally divided into environmental pollution and ecological destruction. Such as forest vegetation destruction caused by deforestation, grassland degradation caused by overgrazing, desertification and land desertification caused by large-scale grassland reclamation, and air and water environment deterioration caused by industrial production.

So far, the environmental problems that have threatened human survival and been recognized by human beings mainly include: global warming, ozone layer destruction, acid rain, fresh water crisis, energy shortage, sharp decline of forest resources, land desertification, accelerated extinction of species, garbage disaster, toxic chemical pollution and many other aspects.
