What are the data of the destruction of the earth?

2. The emission of carbon dioxide and other toxic gases into the air will have a greenhouse effect and destroy the ozone layer.

3. Overexploitation of oil and coal.

4. Be directly responsible for the extinction of a large number of endangered animals.

5. Water pollution.

1992 national exhaust emissions105,000 TEU (excluding township industries, the same below). The emission of smoke and dust in the waste gas is1110000 tons, an increase of 7.6% over the previous year; Sulfur dioxide emissions16.85 million tons, an increase of 3.9% over the previous year; Industrial dust emissions were 5.76 million tons, down 0.5% from the previous year. ?

The annual and daily average values of total suspended particulate matter in urban air in China are 90 ~ 663 μ g/m3, while the average value in northern cities is 403 μ g/m3, which is 6. 1% lower than the previous year. The average in southern cities was 243 μ g/m3, an increase of 8% over the previous year. According to the statistics of 67 cities, 5 1% cities exceeded the annual average level, especially Jilin, Jinan, Taiyuan, Lanzhou, Baotou, Yan 'an and Xi 'an. ?

According to the statistics of 66 cities, the average value in the first half of the month was between 3.8-55.8 tons/km2, slightly higher than that in the previous year. For example, cities are obviously heavier than southern cities. Cities with an average annual dust fall of more than 30 tons/km2 include Sanming, Anshan, Changchun, Datong, Shijiazhuang, Harbin, Yinchuan, Jilin, Hegang, Shenyang, Lanzhou and Tangshan. ?

According to the statistics of 72 cities, the annual average daily value of sulfur dioxide is between 7 and 63 μ g/m3, with the average value of 97 μ g/m3 in northern cities and 90 μ g/m3 in southern cities, slightly higher than last year. Cities that exceed the national third-class standards include Guiyang, Chongqing, Taiyuan, Urumqi, Yibin, Nanchong, Jinan, Shizuishan, Qingdao, Tianjin, Changsha and Datong. ?

According to the statistics of 72 cities, the annual daily average value of nitrogen oxides ranges from l 1 ~ 129 μ g/m3, with the average value of 56 μ g/m3 in northern cities and 40 μ g/m3 in southern cities, which is basically the same as last year. The pollution in Changchun, Jinan and Yuncheng has obviously increased, and Lanzhou, Baoji and Nanchong have improved. ?

In 2000, acid rain was still confined to local areas. According to the statistics of 58 cities, the annual average precipitation pH value is between 3.85 and 7.43, and 52% is below 5.6, all of which are southern cities. The frequency of acid rain in Ganzhou, Changsha and Xiamen exceeds 90%, and that in Nanchong, Yichang, Nanchang, Huaihua, Baise, Nanjing, Chongqing and Guangzhou exceeds 70%.
