Greenpeace submitted their research report to the government of China. According to the report, China people live in a highly toxic environment even at home. Due to the lack of effective supervision, decoration, furniture, electrical appliances, children's toys and other materials contain excessive toxic substances, which are harmful to human health.
Science is progressing every day, and human beings are cheering blindly for scientific achievements every day. Humans thought that they could enjoy the happiness brought by science, and never thought about the possible consequences of unfettered science.
2. Sanlu tainted milk powder incident
The dairy product pollution incident in China in 2008 (or China milk powder pollution incident in 2008, China poisoned milk powder incident in 2008 and China poisoned milk powder incident in 2008) is a food safety incident in China. The cause of the incident is that many babies who ate milk powder produced by Sanlu Group were found to be in kidney calculi, and then melamine, a chemical raw material, was found in their milk powder.
According to the published figures, as of September 2, 2008, there were 39,965 infants who received outpatient treatment consultation and recovered due to the use of infant milk powder, of which12,892 were hospitalized, 1579 were cured and 4 died.
After the General Administration of Quality Supervision, Inspection and Quarantine of China released the inspection report on melamine in infant milk powder produced by domestic dairy companies, the incident deteriorated rapidly, and melamine was detected in milk powder from many manufacturers such as Yili, Mengniu, Guangming, Shengyuan and Yashili. The incident also dealt a heavy blow to the reputation of goods made in China, and many countries banned the import of dairy products from China.
3. Illegal use of freon
In the production and life of modern society, freon is widely used as a refrigerant in refrigerators, a foaming agent for foamed plastics, a cleaning agent for electronic components and precision instruments, and a spray for medicine and hairdressing.
The chemical properties of freon are very stable. After being discharged, most of them accumulate in the air, and then slowly float to the stratosphere at high altitude, where chlorine atoms are separated by photolysis, and chlorine atoms are the "killers" of destroying ozone-1chlorine atom can destroy 65,438+millions of ozone molecules through a chain reaction, which eventually leads to holes in the ozone layer.
4. Global warming
Global warming is due to the accumulation of greenhouse effect, which leads to the imbalance of energy absorbed and discharged by the earth-atmosphere system, and the accumulation of energy in the earth-atmosphere system leads to temperature rise and global warming.
Because people burn fossil fuels, such as oil and coal, or cut down forests to burn them, they will produce a lot of carbon dioxide, that is, greenhouse gases, which are highly transparent to visible light radiated by the sun.
However, it has a strong absorption of long-wave radiation emitted by the earth, and can strongly absorb infrared rays from ground radiation, which leads to the rise of the earth's temperature, which is the greenhouse effect. Global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also threaten human survival.
5. Smoky
Automobile exhaust emissions, waste gas generated by coal-fired heating in winter, industrial production waste gas, dust and other illegal emissions lead to smog.
In 20 13, there were four smog processes, covering 30 provinces (autonomous regions and municipalities). In Beijing, there is no fog for only five days. It is reported that less than 65,438+0% of the 500 largest cities in China meet the air quality standards recommended by the World Health Organization. Meanwhile, among the 65,438+00 most polluted cities in the world, 7 are in China.
