> Especially since the most promising solutions come from rapidly developing technologies and research

What solutions are you referring to?

This sentiment baffles me when I see it. It's not like we learned we'd this problem yesterday, and now we've to guess how we might solve it based on guessing.

For 35 years, "rapidly developing technologies and research" hasn't improved the numbers. I understand that there's a regular stream of news which touts one thing or another as a possible solution, but which one of them has done anything? How long do we wait for this techno-optimism to bear fruit?
