There are nine factors causing environmental devastation in our country which are soil erosion, mining, mineral(chemical) fertilizers and pesticides, solid wastes, waste water, coal, grain consumption, rising sea level and old ideas from people.
The function of artificial soil mechanism lies in that 5-6 billion tons of artificial soil will be made every year from 5 billion tons of residual mineral after ore dressing (except radioactive matter and heavy metals), 1 billion tons of solid wastes produced by industry and construction and coal ash (except harmful matter), about 1 billion tones of human and animal dung and urine, straw, organic rubbish etc. (except harmful matter) in order to balance 5-6 billion tons of soil erosion. So, theoretically the speed of soil erosion in our country will be lowered close to zero and the tendency of natural environmental deterioration in our country will be reversed into renewing development. As long as we hold the line, people will see the future and hope of natural environmental protection in our nation.
