問題詳情
四、閱讀測驗Every community of humans faces a life-or-death question: How do we distribute water? Some water has to be held as a community resource if a town, city, or even nation is to survive. Many early human settlements were based on irrigation systems. These exist because earlier people agreed where the water should flow and to whom. Wells in desert lands are protected by cultural traditions that make them a shared resource among traveling peoples. Many large lakes, such as Lake Michigan in the United States, are mostly reserved for public use, not for the people who own houses on the shores.Water-use laws can prevent a few powerful people from gaining control over all available water. But water lawsdo not make water freely available in equal amounts to everyone. Farmers need huge amounts of it. So do many industries. Families, however, do not need nearly that much. There is also the issue of pollution. Water laws must prevent careless (or intentional) pollution by some users before the water reaches all users.Problems occur when government is not strong enough to make and enforce laws. Often, the water in dispute is an international (or interstate) resource. For example, the Mekong River in Southeast Asia starts in China and then windsthrough Laos, Cambodia, and Vietnam. The Vietnamese government, no matter how conscientious it is, has little control over how much of the Mekong water reaches Vietnam and what kind of condition it is in. The upstream nations, especially China, determine that. As upstream dams take more of the river, Vietnam has a greater need to negotiate an effective water-rights agreement with other governments. International agreements have worked elsewhere. We will see if they will work along the Mekong.
