The main reason for these behaviors was the lack of awareness of protecting the ecological environment and the limitation of scientific and technological level at that time. he
However, this does not mean that these civilizations have not made any principles and attempts that are conducive to environmental protection. For example, in ancient China, there was an environmental protection thought that "mountains and rivers are full, so we should enter the mountains at the right time and prohibit development at the right time", emphasizing the rational utilization and protection of natural resources. In modern society, we should learn from these historical experiences, pay more attention to environmental protection and realize sustainable development.
?
1. Soil erosion: Large-scale deforestation and land reclamation lead to soil exposure to sunlight, wind, hunger and rain, which is prone to soil erosion, leading to river siltation, flooding and other problems. ?
2. Desertification is rotten: unreasonable land use and over-exploitation lead to the decline of land quality, and desertification gradually expands, threatening agricultural production and human living environment. ?
3. water shortage: the over-exploitation and pollution of water resources by ancient civilizations led to the decrease of rivers, lakes and groundwater, which brought great pressure on water supply in modern society?
4. Decreased biodiversity: Destructive development leads to the loss of biological habitats, many species are extinct or endangered, and the diversity of raw and rotten pants is seriously affected. ?
5. Environmental pollution: The pollutants discharged from industrial production and life in ancient civilization were not effectively treated, which led to environmental pollution problems and affected human health and quality of life.
From these historical experiences, we should draw lessons, attach importance to ecological environment protection and adopt the method of sustainable development to avoid repeating the same mistakes.
