If we do disappear tomorrow, nearly all tall buildings will fall to the ground in less than 200 years. The ruins of these buildings will remain for several thousand years. Within 75 years the Ecosystem will completely reshape its self. Species pushed to the brink of extinction will flourish, and stable populations will be threatened by the sudden rise in competition and predators. Some area's modified forestry will return to an unaltered state in a very short period of time, where as others will never return to their natural state. Our effects on the environment, such as Co2 emissions will continue to influence nature for as long as 1000 years. In 20 000 years everything from concrete to plastic, buildings to bridges will be 100% wiped from the face of earth.
However, evidence of mankind on the moon will remain for multiple millions of years.
