( Short papers do not need to be listed in the table of contents) Abstract: It is an excerpt from the main content of the article, which is required to be short, refined and complete. The number of words can be a few crosses, and no more than 300 words should be appropriate.

Paper on Water Pollution, Economy and Environmental Protection

Abstract: Environmental Protection Work is every The responsibility of a water supply and drainage worker is indispensable. Environmentally friendly buildings are the development direction of buildings in the future. This article will pay close to water conservation, energy conservation, water pollution prevention and control.Hand, discuss how to use existing new materials, new equipment and new processes to realize the environmental protection design of building water supply and drainage.

The river is no longer crystal clear. The water is cloudy and mixed with some dirty things. On the bare riverbed, the water is almost exhausted and still stinks.

Do you want to continue to pollute the environment or protect the river? Should I be a destroyer or an environmentalist? Due to the pollution of water sources and the over-exploitation of groundwater, human freshwater resources have begun to be in short supply. Due to deforestation and excessive reclamation, the problems of grazing, soil erosion and land desertification are becoming more and more serious.

Environmental pollution caused by economic development needs to be solved in a timely manner. Behind the rapid and large-scale development of the economy, China's environmental problems are also becoming more and more complex, including air pollution, water pollution, solidEnvironmental pollution and destruction, including body waste pollution, have a serious impact on people's lives.

Therefore, at present, people talk about environmental protection everywhere and always talk about environmental protection, but what aspects should be done to reduce the harm to the environment? First of all, start with the little things around you and save water and electricity. Water pollution in life is quite serious, and one of its main sources is industrial wastewater.

Protecting the Environment Essay 1 Protecting the environment is something that every moral person must do, because this great environment is a precious place for human survival. People not only come from nature, but also receive it from nature. The natural environment makes people rely on the necessary material conditions for survival and development. In today's world, environmental pollution and ecological balance are becoming more and more serious.
