环保是现在全世界最热的一个话题,但许多人听了环保两个字感到与自己很远,更别说去做了。其实环保可以很简单,比如节约,比如简单生活。中国是一个有13亿人口的泱泱大国,每年用水量随着人口的增加而不断增长。世界人口在50年代为25亿,1999年增加到了60亿,增加了1.4倍。农业用水量增加了5倍,工业用水量增加了26倍,家庭、生活用水量则增加了18倍!这是一个个多么不可估量的数字!按 Environmental protection is now one of the hottest topics in the world, but many people feel environmental protection far away from them, let alone done. In fact, environmental protection can be very simple, such as saving, such as simple life. China is a big country with a population of 1.3 billion, and its annual water consumption keeps growing as its population increases. The world population increased from 2.5 billion in the 1950s to 6 billion in 1999, an increase of 1.4 times. Agricultural water consumption has increased fivefold, industrial water consumption has increased 26fold, household, domestic water consumption has increased 18 times! This is a very immeasurable figure!
