I would add to your list of what people need, the recognition and tolerance, even celebration, of cultural differences.
I don't disagree with your addition to the list, but I wonder how much of intolerance is the result of frustration—frustration from the lack of health care, clean water, etc.—which leads to a search for scapegoats (i.e., intolerance).
Certainly "pulling the plug on the human experiment" is one solution, but I don't trust anyone else to make that decision for me, let alone who in the herd gets culled! And never forget, Mother Nature bats last.
