Well, it can be argued that markets caused and will solve our climate change problems. From Fred Pearce in "The New Scientist":
"We need markets and social systems that make the coices for us. Humans shouldn't have to be experts at everything. I want my drains to work and my computer to function without knowing the details of exactly how they operate. This is why a carbon tax would be good. In Denmark we have a 180 per cent tax on cars. That means I've never owned a car. I cycle everywhere - not because I am especially good, but the system encourages me not to buy a car. All the same, the solution will come in the main, not from carbon dioxide taxes but from smarter technologies."
