Who can say when the earth will run out of water to drink? The earth will never have that day. The biggest resource on the earth is water. Aircraft carriers sail in the sea for a long time, but they don't bring much fresh water from the shore. A Nimitz-class aircraft carrier purifies enough fresh water every day for half of new york's daily water consumption. Now everything in the economy and society is inseparable from money. Everyone and every enterprise will spend money according to their own ability. If you have more money, you will spend it. If you have less money, you will spend it. Saving money is for people who can't afford it. Spending money is a contribution to society. Spending money can prosper the economy, increase employment and regenerate wealth. Saving is not always right, just like the current economic recession, the policy is to stimulate consumption and expand domestic demand. Don't use consuming resources as an excuse. Resources are for people, not only water, but also things that people use to see, wear, eat, drink, live and play. A few dollars can make people eat a meal, and millions can also eat a meal. /kloc-you can rent a room for more than 0/00 yuan, and millions of buildings are also occupied. Tens of thousands of dollars is also a car, and dozens of dollars is also a set of clothes. No. They have promoted the development of many industries, created many employment opportunities and increased the national tax revenue. They are promoting social progress. In order to protect water resources, we should start from solving the pollution problem, not from saving water. The water saved by millions of residents in one month is not enough for a large steel plant in one day, so saving water can't protect water resources. People are avoiding the problem of pollution. It is even more ignorant to say that fresh water will become salty after being used, because there is no fresh water on the earth. Fresh water comes from frost, snow, rain and dew ice formed by water essence evaporated from salt water. Frost, snow, rain and dew The ice and water in the air are not salty. As long as there are cream, snow, dew, ice and water in the air, there will be fresh water, and the cream, snow, dew, ice and water in the air will always exist. The main sources of fresh water are rain and melting ice (hail) and snow. The average annual precipitation in China is 600 mm, of which 300 mm is absorbed and evaporated by the surface and 300 mm flows into rivers, lakes and seas. China covers an area of 9.6 million square kilometers and has a population of 654.38+0.3 billion. Every year, the per capita fresh water that God gives to China is 9600000000 * 0.3/65438.
Everyone has heard a lot of words, such as "the surging river flows eastward", "the river belongs to the sea" and "the river is gone forever", which shows that water will flow forever and will not stop for people to use. Whether you use it or not, the surging river will always flow into the sea. Every year during the flood season, a large amount of water flows into the sea from rivers. Does it mean that people waste water? At that time, people prayed to drink less water. Some arid areas have nothing to do with water use since ancient times, not to mention that the universe is moving and the earth is moving. Some places with water will become dry, and some dry places will become Zeguo, just like the Yellow River is cut off, the sea level rises, and rivers and lakes are blocked. It's simple. The way to solve the shortage of water resources in arid areas is to transfer water from south to north, and build more large reservoirs in arid areas. Those who argue that they can't use water are either ignorant or fools to raise water prices.
