09. Since the Earth is so polluted, how would we make sure space would stay clean and not end up like Earth? (A K2S Question)

From The Space Library

First, Earth is not very polluted. Only where there are high concentrations of people such as in cities is the pollution bad. And that pollution is made worse because the pollution often cannot escape because the cities are built in mountain valleys. In space there will not be large concentrations of humans for a while and any pollution will be spread out in the huge vastness of space.
