2. Secondly, China's environmental protection industry is a sunrise industry, and its potential demand is extremely strong. Theoretically, the potential demand space of a country's environmental protection industry is often determined by the relationship between the total environmental pollution caused by industrial production and economic activities and the carrying capacity of the natural environment. Generally speaking, it is customary to use fossil energy consumption per unit land area to estimate the potential demand of environmental protection industry.
Thirdly, the environmental pollution in China is more serious than that in foreign countries, and it needs long-term strict control. Smog control has a long way to go, and per capita water resources are scarce. China's per capita water resources are less than a quarter of that of the United States, and there is also sewage treatment. Compared with other countries, the total amount of sewage discharged from China's limited total water resources is very high, which may be higher than the critical point of ecological environment self-repair.
Finally, people's awareness of environmental protection has been enhanced. Blue sky and white clouds, green mountains and green waters are all loved by the people. Now, we have joined the ranks of environmental protection with many environmental protection organizations and public welfare environmentalists. People's awareness of environmental protection is getting stronger and stronger, and the development of related environmental protection industries is also the general trend.
