@davidho Capitalism has it's flaws, certainly. So does every other form of government. What system then will "solve climate change"? Communism / Socialism? Anarchism? A flavor of total autocracy?
A system is only as determined to solve a problem as the individuals involved. The question really is do we have a critical mass of people willing to swim against the current to do what is right, or do we do what previous generations did and leave the problem on the next generation's doorstep?
