The world has too many people now. The global future is essentially unknowable. Pollution is only a local problem, not a global problem. The rich countries have a moral responsibility to help the poor countries. Global warming is nothing to worry about.
Capitalism is the best possible economic system.
When I retire in about 2050, I'll be pretty well off. I expect the wide income gap between rich and poor countries to shrink in the next century. The global population will peak in the next century at about 10 billion. The market mechanism can solve almost all of our global problems. In the next century most countries will have democratic governments.
