地球的原始生态只需人类进化0.01年的时间便可形成,人类的痕迹数千年后自然烟消云散。仅以纽约为例——人类消失后仅二三十年,纽约的地下管道就会腐蚀变形,街道很快会变成河流。用不了200年,纽约公园的草坪就会被橡树和枫树所取代。荒草和树叶会引发冲天大火,将能点燃的东西统 The primitive ecology of the earth can only be formed by the evolution of human beings for a period of 0.01 years. The traces of humanity will disappear after thousands of years. Take New York only as an example. Only twenty or thirty years after the disappearance of mankind, the underground pipelines in New York will erode and the streets will soon turn into rivers. In less than 200 years, the lawn of New York Park will be replaced by oak and maple. Wild grass and leaves will trigger sky-shattering fires that will ignite
