Environment and Health Composition 1 Water is the source of life. Similarly, air is the source of everything! Without air, there won't be anything on the earth, and we can't live. Air quality directly affects people's health and quality of life!
My grandparents told me that when I was a child, the air was filled with the fragrance of petals and grass, and blue sky and white clouds could be seen everywhere. The river is crystal clear, small fish are playing in the water, and children are also playing in the water. How happy we are! Now, the invisible air has turned into thick smoke, and the smell is mixed with plastic and garbage when walking on the road. Dare not open the window at night, the smell of burning plastic will float into the house, which will seriously affect physical and mental health.
People's living standards are getting higher and higher, and the damage to the environment is getting bigger and bigger! Many families have bought private cars, and the air is filled with countless automobile exhaust; A large number of factories also discharge waste into the air and waste water into rivers; People's wanton demand for nature, such as excessive logging and illegal construction, has led to the destruction of many natural barriers. ......
Environmental pollution and destruction have a great impact on people's health, especially on children whose body organs are not yet mature. Polluted air is very harmful to children's respiratory tract, and sewage can also cause acute or chronic poisoning! It is urgent to improve the environment, purify the air and prevent diseases! We can work hard in the following aspects:
1, try to choose bicycles or hiking, and choose public transportation for long distances.
2. Strengthen the management of the factory, and the discharge of waste gas and wastewater should meet the requirements of environmental protection.
3. Intensify publicity and call on people to protect the environment, plant trees and take care of flowers and trees.
I believe that as long as we act together and care for the environment, we will certainly improve the environment and reduce the spread of diseases!
Environment and Health Composition 2 The human environment can be divided into primary environment and secondary environment. The original environment refers to the natural environment that is formed naturally and is basically unaffected by human activities, and there are many factors that are beneficial to human health. For example, clean water, air, soil with normal chemical composition, suitable solar radiation and microclimate, and beautiful greening all promote health. However, in some areas, the original environment will also bring adverse effects on people's health. For example, due to geographical and geological reasons, there is an abnormal phenomenon that some elements are too much or too little in water or soil in some areas, which affects the intake of these elements by local residents. When the content of some trace elements in human body is too much or too little, it will cause biogeochemical diseases, also known as endemic diseases.
Humans can not only adapt to the natural environment, but also develop and utilize natural resources, transform the natural environment and make the environment more suitable for human survival. The environment formed under the influence of human activities is called secondary environment. Industrial and agricultural production discharges a lot of toxic and harmful pollutants, which seriously pollutes the natural environment such as air, water and soil, destroys the ecological balance and makes the quality of human living environment deteriorate sharply. Human production and living activities discharge various pollutants into the environment, especially in the production process, and with the development of science and technology and industry, the types and quantities of pollutants in the environment are increasing day by day. These pollutants, together with air, drinking water and food, have various harmful effects on human health.
