摘要

More than two-thirds of the Earth's surface is covered by oceans, inland waters and rivers, but fresh water makes up only a relatively small amount of the total of 1.4 billion cubic kilometres. Global water consumption continues to increase as the population grows and, in many parts of the world, people have no running water and are forced to drink directly from contaminated rivers, wells and streams.
