The human, is the earth's children. The earth feed us, nourish our life, we in the earth mother's arms growth. With the passage of time, the human wisdom in condensed, science and technology is in progress, the world in development, the earth, but also in the passage of time change.
Now, nurturing our earth, have holes. In human evolution, earth has in imperceptible to fall away. Ten million years of human history of civilization, is there will be in this generation we fall?
Save the earth environmental obligations and responsibilities is around the corner, we have to do something for the earth.
At present, the earth has ten of the most important issues:
1 the acid rain pollution. Acid rain is the main reason of the appeared in the 1950 s with the development of industry and population surge, human use fuel more appear. His most serious harm is leading to the death of the forest. The world three SuanYuOu, one of which is in the south of the Yangtze river region in China, and the acid rain area accounts for 30% of the land and resources;
2 the greenhouse effect. Human is discharged into the atmosphere of carbon dioxide more and more. The main harm is the polar melting glaciers, rising sea levels is. The greenhouse effect of the main culprit carbon dioxide, our country is the world's second largest emitter, and at present the flowers of the sulfur emissions have oxygen in the world
3 ozone depletion. In 1985 the first time Antarctic survey found the ozone layer over Antarctica have a cavity. Scientists have found that is nearly mankind's masterpiece.
4 land desertification. The earth desert is to one minute and 10 hectares of land speed erosion. The reason for this is the destruction of the vegetation. Land desertification, desert is already in the world each year 6 million hectares of land erosion rate in China, and every day there are 500 hectares of land by desert swallowed;
5 the forest area is reduced. Now the world's forest area decreasing. Now the world each year 12 million hectares of forests have disappeared, according to nearly 10 years of average cutting and destroy the speed of the forest, and to the 5055 will lose all forest;
6, species extinct. Because humans on the ecological environment pollution and destruction, making the earth more and more species have been or are are totally destroyed.
7. A water crisis. Global water only 1% for human use. Our country has more than 600 cities, including 300 plus more (are water shortages, there are more than 40 a severe water shortages. A water crisis, as the world PinShuiGuo 21 one of China, the national more than 600 city, the water shortage has more than 300 block;
8. Water and soil loss. At present our country soil erosion area has reached 367 square kilometers, every year at least 5 billion tons of fertile soil blown away;
9. With rubbish. At present the increasing trash, including industrial garbage and waste has become the world all feel difficult problem. China's garbage because no processing, pollute the air and groundwater.
10. Urban air pollution. Our country urban air pollution is very serious. The cause of the contamination is our country city more and more the exhaust gas of air pollution.
Growing industrial waste, life rubbish has surrounded the two-thirds of the cities in China.
I hope that human beings can insight, starts from oneself, from small start. Different people, different nationality, in order to common homeland, please work!
