朋友们,你尝过口渴的滋味吗?你知道地球上的淡水资源已经为数不多了,但用掉的资源中有很多都是被人类污染和浪费了吗?“如果人类再不珍惜水资源,地球上最后一滴水将是自己的眼泪。”“小草青青,踏之何忍。”“地球是我家,保护环境靠大家!”“抬起手,大家一起做环保!”这些都是随处可见的广告标语,可大家真的都做到了吗?很多人可能早已麻木不仁了。但难道我们能允许自己在将来没有水喝吗? Have you ever tasted the thirst? Do you know that there are only a few freshwater resources on Earth, but many of the resources used are being polluted and wasted by humans? “If humans do not cherish the water Resources, the last drop of water on Earth will be their own tears. ”“ Grass green, how hard to tread. ”“ The earth is my home, protect the environment by everyone! ”“ Raise hand, everyone together Environmental protection! ”These are ad slogans everywhere, can we really do it? Many people may have long been insensitive. But can we allow ourselves to drink without water in the future?
