The world emits more than 600 million tons of gases that pose a great threat to mankind every year. It is estimated that by the middle of the next century, one third of the earth's surface will be in danger of desertification, and 60 thousand square kilometers of land will be desertification every year, threatening more than 60 countries ... See these shocking figures. How do you feel, my friend?

Engels said: "We should not be too intoxicated with our victory over nature. Every time such a victory, nature is retaliating against us. " Isn't it? From the appearance of apes to the highly developed civilization era, human beings have never stopped asking for nature, and nature is also "responsive", which further breeds human greed. They wantonly cut down trees on the earth, set up chemical plants and discharge pollutants and wastes. As a result, once the mountains and rivers were beautiful, the blue mother earth looked devastated and filthy. Why isn't this chilling?

Environmental pollution also makes human beings suffer. Let's look back at history and see how our predecessors were punished by nature. These are the eight major public hazards in the world:

(1) The Maas Valley Incident in Belgium:1In February, 930, the industrial waste gas and dust discharged from the Maas Valley Industrial Zone in Belgium had a comprehensive impact on human body. Nearly 60 people died in a week, the mortality rate of patients with heart disease and lung disease increased, and the mortality rate of livestock also increased significantly.

(2) The smog incident in Los Angeles, USA: In the 1940s, photochemical smog produced by a large number of automobile exhaust in Los Angeles caused many people's eyes to be red and swollen, pharyngitis, respiratory diseases aggravated, and even thinking disorder and pulmonary edema.

(3) Donora incident in the United States: 5438+0984, 10. In June, sulfur dioxide and its oxides combined with atmospheric dust in Donora town, Pennsylvania, USA, causing serious air pollution, resulting in 59 1 1 person's sudden illness.

(4) Haze in London, England: 1952,1February 5-8, four days in London, England, and more than 8,000 people died in February.

(5) Minamata disease in Japan: 1953- 1968. In Minamata Bay, Kumamoto Prefecture, Japan, people ate fish, shrimp, shellfish and other aquatic organisms rich in mercury and methylmercury in the bay polluted by mercury-containing sewage, resulting in nearly 10,000 people suffering from central nervous system diseases, of which more than 60 people died of methylmercury poisoning.

(6) Exhaust gas incident in Niigata, Japan: 196 1 year, the exhaust gas from oil smelting and industrial fuel in Niigata, Japan seriously polluted the atmosphere, causing a sudden increase in the incidence of respiratory diseases, especially asthma, and forming a prominent environmental problem.

(7) Rice bran oil incident in Aichi, Japan:1In March, 963, rice bran oil was mixed with polychlorinated biphenyls (PCBs) pollutants due to poor production management in Aichi, Japan. After people ate this polluted oil, more than 13000 people were poisoned and hundreds of thousands of chickens died.

(8) Pain in Toyama, Japan: 1955- 1977. People living in Toyama, Japan, suffered from diseases caused by drinking cadmium-containing river water and eating cadmium-containing rice, and treated 258 patients, including 207 deaths.

Of course, environmental problems are not limited to these, such as deforestation and massive emission of greenhouse gases, which are all caused by human ignorance of nature and digging their own graves. Indeed, environmental problems have been plaguing the whole world. But who directed this tragedy? It's people. When the disaster comes to mankind again and nature takes endless revenge on mankind, mankind finally wakes up and understands the importance of environmental protection. If human beings want to conquer nature, they must respect it. We should not only carefully transform nature, but also boldly practice and boldly improve it, so as to control nature and make our own interests develop harmoniously with nature.

Facing the severe environmental problems in China, we can't repeat the mistake of "pollution first, then treatment" in western developed countries. "Pollution first, then treatment" is a very unwise choice, and the cost of treatment is very high. We should not only speed up development and get rid of the constraints of environmental problems on China's economy, but also implement the policy of putting prevention first and combining prevention with control to protect the environment.

"Don't do it with kindness and smallness", I think everyone understands. Protecting the environment starts with small things, such as picking up an abandoned battery, recycling waste products and refusing to use ultra-thin plastic bags. If everyone can do it, the world environment will be greatly improved. If you do, it means that you have made a certain contribution to protecting the environment. If you haven't done it yet, keep doing it from today, and slowly, you will find that everything you have done has produced wonderful results.
