Lack of water in the next 30 years threatens half the world

40% of the world's regions will face a severe water shortage over the next 30 years, according to Suez Environment, Europe's second water resource company, a problem that leaders in the Copenhagen weather Summit urgently need to address. suezenvironnement Louise Shosad Jean-louischaussade, chief executive of the Suez Environment Group, said many developed countries and regions, including Australia, the southwestern United States and Spain, will struggle to meet their people's demand for water.　　Developing countries such as the Middle East, North Africa, China and India face similar problems, with water resources struggling to meet population and agricultural needs. Chaussade also lists a long list of infrastructure that water companies need to build.　　The large-scale cultivation of desalination plants, the direct conversion of seawater into drinking water, will be in extreme cases, to solve the world's water supply difficulties. "Over the past 20 years, human productivity and capital values have increased dramatically," Chaussade said. For a long time, people have neglected the productivity of resources, until now, we are aware of the effective use of them. We still have many opportunities to reduce environmental damage and conserve resources. In addition to improving the efficiency of agricultural water use, urban water saving is also an efficient choice.　　"He also pointed out that not only to the agricultural and industrial waste water treatment, people must also consider the development of other progressive water resources utilization path." Earlier this year, scientists at World Water Week (Worldwaterweek) warned leaders that the world's water resources should be included in the Copenhagen climate conference agreement.　　Experts believe that weather changes will lead to changes in weather models, which will change the supply of water resources, affecting the scope of agriculture, energy production, forestry and industry. Anders Bent, a senior official at the Stockholm International Water Research Institute (Internationalwaterinstitute), said at the recently opened Copenhagen weather Summit: "The current issue of water resources has not received enough attention from the participating countries." Countries should carefully study the impact of the water crisis and the importance of water for Earth and human health. "(Julie Meng)
