(1) Introduction
A good natural environment is the material basis for human survival and continuation. The natural environment refers to the range of life on the earth, usually called the biosphere. The biosphere is a circulatory system that follows the law of balance and has a natural self-purification. If the self-purification of nature is destroyed artificially, the environment will be polluted, human beings will be punished and even threaten their own survival.
Protecting the environment is the obligation of all mankind, because we only have one earth!
(2) factual arguments
The water pollution in China is very serious.
Rivers and lakes in China are generally polluted to varying degrees. At least 30 billion tons of sewage is discharged every year, with an average of 80-90 million tons per day. More than 85% of them were buried in rivers without any treatment. Organic pollution is serious in the Yellow River, Pearl River, Huaihe River, Songhua River, Liaohe River and Haihe River basins. Among the four major sea areas, the Bohai Sea and the East China Sea are seriously polluted, with frequent red tides, and the deterioration of water quality in coastal waters is becoming increasingly obvious.
Protect our environment.
China has built a "Three-North Shelterbelt", which has effectively controlled the southward invasion of sandstorms. In order to control the water pollution in Huaihe River within a time limit, the government ordered factories and enterprises on both sides of Huaihe River to discharge wastewater within a time limit, and all those that failed to meet the standards within the time limit were closed. At present, the same measures are being taken to control the sewage discharge of factories and enterprises along other rivers and lakes, thus effectively stopping the pollution of water resources; The formation of the Baolan desert protection net has accumulated human experience in overcoming desert sandstorms. The vegetation reconstruction project in the upper reaches of the Yangtze River lasted for more than 20 years and achieved remarkable results. Recently, reconstruction efforts have been intensified, natural forest logging ban areas have been demarcated, and mountain closure areas have been expanded. The State Council has decided to invest 90 billion yuan at the end of this century to rebuild the environment of the Yangtze River, Pearl River, Qiantang River, Taihu Lake, Poyang Lake and Chaohu Lake.
The world-famous "Minamata disease"
Minamata Bay is a beautiful bay in Japan. Fishermen in Minamata Town have lived on rich seafood for generations. 1950, a strange phenomenon happened in the town: some cats suddenly got strange diseases, walked unsteadily, kept cramping their limbs, and finally jumped into the sea and drowned. Soon, the local residents also got this strange disease. The symptoms are very similar to those of a sick cat. First, I slurred my speech, walked stagger, then my muscles trembled, my body curled up, I cried wildly, and finally I died in extreme pain.
It was not until 1969 that the cause of this strange disease was found out: there was a nitrogen fertilizer company in Minamata town, which used mercury as a catalyst in its production process. The waste water and waste residue discharged by this company into Minamata Bay contains mercury. When mercury enters animals or humans, it will paralyze the central nervous system and lead to death over time.
In Minamata Bay, seawater is polluted by mercury-containing wastewater, and marine life is poisoned by mercury. Marine life forms a "food chain" and accumulates one after another. Speaking of big fish, the mercury concentration is 1 10,000 times to110,000 times higher than that in seawater. Cats and people eat aquatic products with high mercury content and get terrible Minamata disease.
