珍惜生命为主题的手抄报，珍惜生命防溺水的画

Yes! The vast and boundless sea, vast lakes, surging rivers, magnificent glaciers and flowing spring water are all kinds of water, which make our human homeland look beautiful and bring vitality to the earth. Can you imagine what the earth would be like without water? It will be a yellow and dead silence. Without water, there would be no plants, no animals and no people. Water has given birth to life on earth and human civilization, and people's life and industrial and agricultural production depend on boiled water. Water is the source of life and the lifeblood of economy.

People regard water as a free gift from nature to human beings, and use it and enjoy it. But 进入After the middle of the 20th century, water began to become scarce and irreplaceable. More and more cities are crying out for water shortage! The 1977 联合国Water Conference warned that water will soon become a profound social crisis and the next crisis after the oil crisis will be water. Water resources crisis is becoming one of the major and urgent environmental problems facing mankind.

I remember I have seen a movie before: in a mountain area in 中国， where water is very scarce, water is drawn from dozens of miles away. When it rains, everyone moves all the containers in the house to contain rainwater. However, we are still wasting water resources and destroying water resources. Is this not tantamount to committing a crime? I have done an experiment once. If you wash your hands normally, you only need about 0.5 kg of water, while if you wash your hands wastefully, you need about 2.5 kg of water, which is about 5 times as much as normal hand washing.

Facing the challenge of water, we must clearly realize that water resources are limited and there is nothing in the world to replace water! In history, how many places have their oases turned into deserts and cities into ruins due to the depletion of water sources. For example, the ruins of the ancient city of 楼兰in the desert of 塔克拉玛干and the ruins of 统万城in the desert of 毛乌素are witnesses. One was once a prosperous shopping mall on the ancient Silk Road, and one was once the capital of Xia State. Due to lack of water, it is now submerged in quicksand. If there is no water in a place, people can move to another place, but if all the clean water on the earth is dirty and exhausted, where should people move?

Now, we must face the fact, especially in a country like us, one of the world's 13 water-poor countries, where per capita water resources are scarce and pollution is serious, the water resources on which we depend for our survival are deteriorating. However, more water is wasted and destroyed. I once read a very surprising document: China produces twice as much food as 美国does. The water consumption of China's 10,000 yuan output value is more than double that of developed countries!

I am convinced that as long as we cherish and cherish water resources. Who should be managed and used well? No abuse, no waste and no pollution of water quality, good allocation and use, coupled with some science and technology, and continuous expansion of water sources, our future generations will no longer have to worry about water shortage, and the world will surely have a better tomorrow!
