节约水资源，保护全世界
每年的节水日是3月22日，至3月28日，它的意义在于告诉人们节水的重要性。
地球的储水量是很丰富的，共有14.5亿立方千米之多。但是其中海水却占了97.2%，陆地淡水仅占2.8%，面与人类生活最密切的江河、淡水湖和浅层地下水等淡水，又仅占淡水储量的0.34%。更令人担忧的是，这数量极有限的淡水，正越来越多地受到污染。据科学界估计，全世界有半数以上的国家和地区缺乏饮用水，特别是经济欠发达的第三世界国家，目前已有70％，即17亿人喝不上清洁水，世界已有将近80％人口受到水荒的威胁。我国人均淡水为世界人均水平的四分之一，属于缺水国家。，全国已有300多个城市缺水，已有29％的人正在饮用不良水，其中已有7000万人正在饮用高氟水。每年因缺水而造成的经济损失达100多亿元，因水污染而造成的经济损失更达400多亿元。
可怕的数据表明：水资源短缺成了当今世界面临的重大危机。因此，保护和更有效合理利用水资源，是世界各国政府面临的一项紧迫任务。那么，怎样才能保护和更有效地合理利用水资源呢？从环境角度来说，最完善的措施是拦水和调水。改变水资源的时空分布。但这只是一个方面，而对于人类来说，更重要的是注重节约用水，提高水资源利用率：在工业方面提倡节水产业，控制污染物的排放，加强废水处理；在农业方面应采用先进的灌溉方式（喷灌、滴灌）等。水是生命的基础，它不仅关系到人类生活的质量，还影响到人类的生存能力。所以增强水的危机意识，珍惜水，节约水，保护水资源，才是当务之急。(Conservation of water resources, protection of the world
The annual water day is March 22nd, to March 28th, its significance is to tell people the importance of saving water.
Earth's reservoir of water is very rich, there were as many as 1450000000 cubic meters. But the sea is occupied 97.2%, terrestrial water accounted for only 2.8%, face and human life is most close to rivers, freshwater lakes, freshwater and shallow groundwater, and accounts for only 0.34% of freshwater reserves. More worryingly, this very limited amount of fresh water is increasingly polluted. According to the scientific community is estimated, the world has more than half of the countries and regions lack of drinking water, especially economy is owed develop the country of the third world, at present already 70%, namely 1700000000 people do not drink clean water, the world has nearly 80% population by water shortage threat. China's per capita freshwater for 1/4 of the world average level, which belongs to the water shortage countries. , there are more than 300 city lacks water, more than 29% people are drinking bad water, and more than 70000000 people are drinking high-fluorine water. Each year due to lack of water caused economic losses amounted to about 10000000000 yuan, because the water pollution caused economic losses amounted to about 40000000000 yuan more.
Terrible data indicate: the shortage of water resources has become the major crisis facing the world today. Therefore, more effective protection and rational utilization of water resources, is the world's governments are faced with urgent task. So, how to protect more effectively and reasonable use of water resources? From the angle of environment, the most perfect measure is the water retaining and water transfer. Changes in the spatiotemporal distribution of water resource. But this is only one aspect, and in humans, is more important to pay attention to saving water, improve the utilization efficiency of water resources: industrial water-saving industry, to control the emission of pollutants, enhanced wastewater treatment; in agriculture should adopt advanced irrigation methods ( such as sprinkler irrigation, drip irrigation ). Water is the basis of life, it is not only related to the quality of human life, but also affects the human survival ability. Therefore, to enhance awareness of water crisis, to cherish the water, save water, protect water resources, it is a pressing matter of the moment.)
