问答题 Lester Brown of the World watch Institute, an environmental watchdog based in Washington, D.C. warns that China's water problems will have global repercussions. Brown calculates that shortages will cut China's annual agricultural output by 9 million tons, forcing it to buy grain. This will push up world food prices.

【正确答案】
Water resources in China now is facing an unprecedented crisis and calling for our serious consideration. Because of the country's population swelling, surging water consumption in towns and cities grows dramatically. Reckless industrial and agricultural water use causes great inefficiency. All these contribute to strain our already strapped water supplies. Worse still, we have to face such an awkward phenomenon: many of China's rivers, including the legendary Yellow River that we are once proud of, are dying out.
Measures must be taken right away to reduce the worsening of the situation. First, it is up to the government to impose the domestic firms to introduce water conservation and recycling programs, through which we can use water more efficiently and of course, save lots of water. Secondly, steps must be adopted to curb rapid deforestation and soil erosion across the country in order to preserve the water table. Thirdly, hydropower that results in large evaporating can be replaced by wind or solar energy. With these measures taken, the water problem will be greatly improved, but none of these will function without our consciousness to improve the dilemma.
