Water is the source of life, cherish
Yeah! The boundless sea, the wide lakes and rivers of ice, magnificent, bubbling springs... These kinds of water, our human homes, particularly beautiful dress to the earth brings great vitality. Can you imagine, if there's no water, the earth would be what kind of? It will be a yellow, a lifeless. No water, no plant, no animal, nobody. Water and earth, and mankind civilization, the life of people's life and industrial and agricultural production is inseparable from the water. Water is the source of life, is the lifeblood of economy!
People put water to human nature as a free gift, the use of it, to enjoy it. But after the middle of 20th century, the water began to become scarce, and there is no generation rarity! More and more urban water dries out the sound! 1977 UN water meeting warned: water will soon become a profound social crisis after crisis, continue to oil the next crisis is water. Water crisis is currently facing humanity, chasing after major environmental problems of the pressing.
Remember I had seen such a film: a shortage in China in the mountains, and to draw water from dozens of miles, a rain all the house all vessels full fill out, but we are still rain in waste water, water, isn't that damage to the crime? I had done a test, if wash hands only a normal 0.5 kilograms of water, the use of waste water and if wash hands will use a method about 2.5 kilograms of water, is about five times the normal wash!
Facing the challenge of water, we must realize soberly, water resources are limited, nothing in the world can replace water! Historically, many places, because the source of exhaustion, oasis becomes desert, city become ruins. Example: the taklimakan desert loulan city in ruins, ruins of maowusu desert ec is witness wancheng. One was the ancient silk road, a prosperous city is the capital XiaGuo pashupati rana, because there was no water, are now covered in quicksand. A place without water, people can be moved away, but if living on earth all the clean water are dirty, the people to move?
Now, we must face the fact, especially as we such a world PinShuiGuo 13 countries, per capita water which is one of the few plus pollution is serious, we have to survive worsening water! But, more people waste water, and destruction. I have seen a very surprised me material: same grain production in China than in America, a multi-purpose water, The Chinese yuan output water than developed countries twice!
I believe that as long as we cherish and love. The one who properly, not abuse, don't waste water, without pollution, plus some redeployment of science and technology, and constantly open water, our offspring won't have to worry about, for lack of the world will be more beautiful tomorrow!
