Er, yes. I am almost amazed that you should need to point this out to DT.Themis wrote: ↑Sat May 30, 2020 2:54 amTo some extend it will help feed the masses, but no it does not solve the overall problem. Sending the masses to Mars doesn't help either. There are massive amounts of Land in places like northern Russia and northern Canada. We don't grow much of any food there because it is not very practical, but if we ever decide to, it will cost a fraction of what it would cost to try doing the same on Mars. Even the MOON would be a lot cheaper. Colonizing Mars is something I would like to see, but it will not solve overpopulation on earth, so it would be better to focus on things that can solve the overpopulation on earth.
Er, yes again. That is blindingly obvious to anybody who thinks about how far away Mars is, and how difficult and dangerous the journey there and back will be - if, that is human beings are ever foolhardy enough to attempt the trip in person, instead of sending robots.Gunnar wrote: ↑Tue Jun 02, 2020 8:45 amEven if Mars is successfully colonized, and the Martian colonists are so spectacularly successful in finding ways to raise food on Mars that they actually manage to produce a surplus, there is no way it would be economically feasible to ship any of that surplus all the way to earth help feed the starving masses here.
DT, the urgent problems that face humanity have to be solved on this planet. Fantasies about interplanetary colonisation are simply that - fantasies, at least within any time scale within which the survival of our present global economic and ecological structures, and hence of our current population levels and distribution, will be decided.
