In today's world, science and technology are developing rapidly, living standards are constantly improving and the world is making progress. However, with the development of human society, when people are enjoying the happiness brought by new technology, they suddenly look back and find that there is endless environmental pollution behind them, so human beings begin to pay attention to the living environment and conditions, and there are more and more demands for improving the environment. If the economy wants to develop and the society wants to progress, is it necessary to pollute the environment or even destroy the nature on which human beings have depended for thousands of years? The flowing water of childhood is no longer clear, the sky of childhood is no longer blue, the scene of snowball fights on New Year's Eve has faded, and only the bleak white snow left on the drawing board covers the door ... All good memories disappear into the huge chimney of the city, full of automobile exhaust. The traces of green are shrinking quietly, and garbage covers this loess. As far as China is concerned, although it has a vast territory and abundant natural resources, the per capita annual output of municipal solid waste in China is large enough to make it collapse. 1996, the amount of municipal solid waste in China reached1000000 tons, and it increased to 10% at an annual rate of 8%. Over the years, the storage of garbage has reached more than 6 billion tons. Plastic bags are called "the worst invention of mankind" because they are difficult to be disposed of as garbage, which has become a major problem in garbage disposal. These rubbish have surrounded more than 200 cities in China, covering an area of more than 500 million square meters. By 2000, the annual output of urban solid waste in China will reach 654.38+0.5 billion tons. Become one of the serious problems of mankind. Pollution before treatment is also a severe pain in the development of western society. Don't we know how to learn from their development experience? Will we repeat the same mistake?
Due to the rapid development, there are countless examples of water pollution endangering human beings. The "bone pain disease" in Japan belongs to heavy metal poisoning caused by metal pollution in water sources. Due to the diversity of emergencies, people are skeptical about the water they drink again and again, and even suspect that they are afraid of mixing some toxic gases in the process of producing tap water, so they think that pure and high-consumption products such as pure water and mineral water are healthier. In fact, the production of tap water that meets the national standards will not endanger human health, and the state still has some preventive measures.
Therefore, even if the development of science and technology leads to pollution, it should not be treated after pollution, which is not conducive to the improvement of people's living standards and social development. We can't kill the goose that lays the golden egg. Although pollution is inevitable in development, as long as we have a strong sense of hardship, learn from the experience and lessons of developed countries, improve human awareness of environmental protection, and learn to solve environmental pollution problems by combining prevention and control, we can turn garbage into renewable resources, make good use of resources, let people find the balance between economic development and environmental protection, and highlight the harmony between man and nature.
You see, on the blue planet, there is a little green light flashing, just like the starlight in the quiet night sky when I was a child ... that is the trace of green.
