People often think that water will never run out. There is a lot of water, such as rain, water from rivers and wells. It seems that water is always available around us and we never have to worry about water scarcity. In fact, water is quite limited on earth. With the rapid increase in population and rapid development of industries, water is more necessary than before. At the same time, a large amount of water is polluted and wasted every day. Some large Chinese cities are already facing the problem of water scarcity. There, the water supply is controlled and industry has been limited. China says water reserves will be exploited by 2030 written by Chris Bukley reports: China will have exploited all available water reserves to the limit by 2030, the government has warned, ordering officials to prepare for the worst due to warming globalization and economic expansion drying up lakes and rivers, the state council issued a directive: “Taking full account of water conservation, by 2030 our country's water use will reach or approach the total volume of resources exploitable water, and the situation of combating drought will become increasingly serious”. China's water supply is going through a massive transition and is facing numerous challenges such as rapid urbanization, the growing gap between rich and poor, as well as between urban and rural areas, as well as water scarcity, contamination and pollution . Much has been achieved in recent decades in terms of increased access to services, increased treatment of municipal wastewater, creation of legally and financially separated water and wastewater services from local governments, and increased cost recovery as part of the transformation of China's economy towards a more paper-based market… citizens should take effective measures. I think first and foremost people should be informed about the real water situation. Everyone should consciously save on water and some laws should be enacted so that water does not get polluted. We must protect existing water resources and develop new ones. In this way I believe that our cities will no longer be thirsty for water in the future. The government should establish rules to improve the ecological environment. Factories that discharge polluted water into rivers and lakes should be severely punished or fined, and a deadline should be set for building water purification plants. We must economize our water use, accelerate water pricing reform, and establish a fair and sustainable pricing system. Last but not least, birth control policy should be pursued more strictly, especially in densely populated areas and rural areas.
