关于水的,要求:1为什么重要2破坏水资源的形式3建议
答案
水是人类及其他生物繁殖的基本条件,是人类生活不可替代的重要资源.有这么一则公益广告:“人类最后一滴水,就是自己的眼泪!”此时,我仿佛看见一滴硕大的眼珠滚落而下,坠地有声.泪珠的后面到处是裂开的土地,枯死的庄稼,我隐隐听见大自然因干渴垂危而发出的痛苦***.
人类不爱惜水资源,不保护生态平衡,终究还是尝到了自己种下的苦果.如今,很多人天天喝着受污染的水,咀嚼着受污染的粮食.人们在享受现代工业文明的同时,也遭受着水污染带来的威胁,由此而造成社会损失和经济损失非数字可以罗列.这是大自然对人类的报复,是对人类咎由自取的大嘲讽!
水是生命的源泉,是万物赖以生命的基础.节约用水,保护水资源是我们每一个人义不容辞的责任.为了那可爱有容易破碎的地球,让我们一起珍惜水资源,保护水资源吧!
Water is the humanity and other biological reproduction of the basic condition of human life, is an indispensable and important resource. There is such a public service ads:" human the last drop of water, is my tears!" At this point, I saw a drop of huge eyes roll down, falling sound. Tears behind is full of dehiscence of the land, the dead farm, I faintly hear Nature dying from thirst groan.
Humans do not cherish the water resource, protect ecological balance, it tasted the bitter fruit of the seeds of their own. Nowadays, a lot of people every day to drink the polluted water, the chewing of contaminated food. People in the enjoyment of modern industrial civilization at the same time, also suffered from water pollution threat, due to the social and economic losses can be listed for digital. It is human nature to revenge, is to the human bring trouble to oneself big irony!
Water is the source of life, all depends on the basis of life. Save water, protect water resources of every one of us is obligatory responsibility. For the lovely and easy broken earth, let us cherish the water resource, protect water resources!
