People are staving to death in Yemen, and we spend billions on Mars rovers, and we put money aside to go back to the Moon. Is this insanity ?!.
The United Nations tried getting food to those in need in Somalia, in the 1990's. Because of the warring factions, it was a total failure.
When you have warring factions in these third world nations, you can't solve food issues. They have to first end the conflicts, then the UN can look into helping them rebuild their basic agricultural practices and food distribution system. Also, it's not up to just the US. We get a lot of our food products from outside the US, especially in the winter, where most of our food products come from South America, which is "green" year around and thus doesn't have a limited growing season. So, complain to the UN.
Separately, at some point in the future, ten years, a hundred years, a thousand years, et cetera, this planet will get hit with an extinction level event by an asteroid that is too big to divert and then it's all over for humanity....or....our sun expands (it does have a life span you know) and there again, it's the end of our descendants. So, to ensure humanity's survival, expansion to the stars is essential and the scientists at NASA have finally come up with a warp-drive theory that is actually workable. So, we may see mankind spread through the universe (not in our lifetime, but eventually) and to keep saying it's more important to keep pumping wasted dollars into conflict areas, perpetually postponing space programs, is in the long term, self destructive.
