> We can solve those problems withing sending more rockets to space - which ends up burning more fossil fuel. Remember, every day that you are alive ( assuming you are living a developed country ) you are emitting huge amount of carbon. Even if you launched 10 rockets a day, it's a tiny percentage of combustion compared to hundreds of millions of cars, trucks, buses, planes, coal and oil and gas boilers, etc. I don't understand your second point. But regarding "clean water on[sic] space", there are in fact ice comets containing tons of water that could be harvested by a future space colony. It makes sense that we'd want to exploit that source rather than try to move H2O into orbit from the Earth's surface. The Jupiter moon Europa is thought to possibly have a vast water ocean beneath its icy shell. The Moon may also harbor vast amounts of water locked in minerals or in subsurface ice. With water, we can have colonies. Colonies can grow trees, entire forests in fact. The sky's the limit, so to speak. Really, there's a lot of exciting possibilities for spreading civilization into orbit and onto other planets and moons. The spin-offs and economic expansion that space colonization will undoubtedly bring more than justify the costs of exploration. A few space colonies and mining operations will solve poverty on Earth. It's worth it.
