英国用水"加剧全球危机"

　　Forecasts suggest that when the world's population soars beyond 8bn in 20 years time, the global demand for food and energy will jump by 50%, with the need for fresh water rising by 30%. But developing countries are already using significant proportions of their water to grow food and produce goods for consumption in the West, the report says. Key to the report is the concept of 'embedded water' - the water used to grow food and make things. The average UK consumer uses about 150 litres per day, the size of a large bath. Ten times as much is embedded in the British-made goods bought by the average UK consumer; but that represents only about one-third of the total water embedded in all the average consumer's food and goods, with the remainder coming from imports.

　　据估计，世界人口将在20年内超过80亿，届时全球对食品和能源的需要将增加50%，对净水的需求将增加30%。然而报告称，在发展中国家，很大一部分的水都用于种植和生产出口给西方的食品与商品。报告中的关键是“内含水”这一概念，即种植食品和生产商品所用的水。英国消费者平均每天使用约150升水，体积相当于一个大浴缸的大小，而英国消费者购买的国货用水量是这个的10倍。但由于其他商品来自进口，国货用水只占消费者平均每天购买食品与商品所用水总量的1/3。
