it's more about the cost or limited interest than the "damage" done to earth

people talk about space tourism, a completly useless business that would end quickly as soon the economy suffer

the only thing worth is a space based industry and especially moon, asteroid and planet mining and "worth" is the most important thing here because for now it's completly impossible or at a completly absurd cost that make it not worth it

USA and China are fighting to place the first human base on the moon, it's more of a cold-war competition than anything else, unfortunaly physic tell us that humanity living outside earth and exploiting space is extreamly difficult and not worth it (for now?)
