The answers are never simple. Anarchy, feed the starving children, raise third world standards up to first world comforts, lower the human population, religion, dissolve the civilization structures, destroy dams, free animals, stop eating meat, increase education standards, communism, democracy, capitalism. These are all easy solutions for our problem. Any problem can be boiled down to a symptom human of overpopulation, that doesn’t mean the problem is simple. Authentic attempt is in every direction. There are people who make heartfelt, selfless attempts to solve the problem they they consider to be most pressing. People legitimately think their religion is provides an answer.
The point is that there are people interested in changing the problems they have an understanding of. Personally I am engaged in the discussion of what the problems are and what their solutions are. I think every problem is a symptom of human over population, whatever the problem is.
