地球总水量虽然巨大,但97.3%是人们尚不能直接利用的海洋咸水；淡水仅占2.7%,而对人类生活最密切的湖泊、河流和浅层地下水等淡水资源,仅占总淡水储量的0.34%,其中能够开采利用的又只有0.2%.世界淡水资源在时间和空间分布上极不均衡,使有限的淡水资源不能被充分利用.据统计,全世界有100多个国家缺水,严重缺水的已达40多个

Answer 1

Although the total amount of water on earth is huge,people still can not directly use seawater which account for 97.3 percent of the whole water body. That means fresh water——the rest, accounts for 2.7 percent only. Furthermore,those water source which is of great intimacy to human living such as lakes,rivers and subterranean water occupies only 0.43 percent of whole fresh water reserves.The extreme imbalance of global freshwater distribution,no matter dimensional or temporal,make it difficult to use this limited source sufficiently.According to statistics ,there are more than 100 countries suffering from water deficiency.Forty of them have more serious water problem.
