Any life is inseparable from their living environment. Human beings are closely related to the natural environment. The pollution of living environment always threatens people's health. There have been many environmental pollution incidents in history, which have had a great impact on health.

1,1At the end of 930, a large number of irritating chemicals were scattered in the smoke and dust of coking, steelmaking, power generation, zinc smelting, fertilizer and other factories, causing thousands of people to get respiratory diseases, with symptoms such as tears, sore throat, cough, chest pain and dyspnea, and about 60 people died.

2. 1948 10, air pollution occurred in Donora town, USA. Within 4 days, 59 10 people became ill and 17 people died.

3. 1968, residents in Kyushu, Japan ate improperly treated and contaminated rice sugar oil, and more than 5,000 people developed edema, rash, nausea and vomiting, and 16 people died.

And the list goes on. Environmental pollution is the enemy of human health and longevity. Among the victims, middle-aged and elderly people bear the brunt. Environmental pollution is extremely harmful to life. Some studies believe that the environment is the main cause of cancer. 80% of cancers in the United States are caused by environmental factors. This is related to the fact that developed industries do not pay attention to environmental protection, so that the living environment is polluted by some chemicals. These substances are carcinogenic. So now all countries in the world attach great importance to environmental protection and set up special worldwide organizations. China also has institutions in this field, and the State has promulgated the Environmental Protection Law. It is an important strategic task for the central authorities to call on the whole country to vigorously carry out afforestation activities. Doing a good job in greening is of great significance for preventing air pollution, protecting and beautifying the environment and enhancing people's physical and mental health.

All these remind people that the environment is closely related to health. Therefore, we should protect the beautiful environment endowed by nature and constantly transform and beautify the environment. Living in a beautiful environment is also an important condition for longevity. Especially the middle-aged and elderly people, their physical condition will naturally decline, and they will get worse and worse with the growth of age. They can't stand the influence of polluted environment, and their physical health will inevitably lose their compensatory ability and decline. So the natural environment has a great influence on health.
