在人们的印象中,地球是一颗蔚蓝色的星球,地表的71%被水体所覆盖。可是一直以来人们却忽略了一个严峻的事实:适合人类饮用的淡水只占地球总水量的0.025%。让这一数字雪上加霜的是,全世界每年会有4000多亿吨污水排进这仅有的淡水中。缺水,已成为响彻全球的警报:全世界80多个国家和地区严重缺水;水体污染让世人苦不堪言:全世界约有12亿人缺乏安全饮用水,每年有300多万人死于不洁饮用水直接引发的各种疾病。
In people’s minds, the Earth is a blue planet, 71% of the surface covered by water. However, people have always overlooked the grim fact that freshwater suitable for human consumption accounts for only 0.025% of the total water in the earth. To make this figure even worse, there are more than 400 billion tons of sewage discharged into the only fresh water each year in the world. Water scarcity has become a global alarm: severe water shortages in more than 80 countries and regions in the world; water pollution that mires people worldwide: About 1.2 billion people in the world lack access to safe drinking water and more than 3 million die each year In unclean drinking water directly caused by various diseases.
