And that the answer to a lot of global problems is to reduce poverty. People who struggle to stay alive are focused on that. People who no longer have to struggle have the luxury of caring for their environment.

For example: most of SE Asia burns their rubbish in their back yard, because there are no rubbish collection facilities. They also litter, throwing plastic waste into the gutter, because they're too busy dealing with other stuff to care. But the wealthier countries (Singapore is the classic example) don't do this and are fastidious about waste management.
