er... no offense but these questions really do not look like a lot of thought was put into them.
Majority of crime, majority of environmental damage. In the U.S.? North America? Worldwide? Developed nations? etc.
Also, monetary incentive does not "cause" anything outside of the human brain. That's why it's called "incentive".
Which option can solve the majority of human problems? Well it's obviously not science since science is just a methodology. Most of the world's problems are caused by governments, so that option would certainly be odd. Beliefs/mindsets is WAY too broad a category.
Number 4 doesn't even make sense.
Finally, number 6 depends entirely on the time frame.
