I think it is the debt-based economic system that has to change, the root of many problems including climate. Their exponential bank-money system is nuts and drives a linear materials system making it even more nuts. Trying to make climate policy in this money-powered political/economic environment is nuts. We have to change the system, from private profit-based money, to public care-based money. We need to return money to its proper role as a public asset-based, not debt-based, money system. The world is $305 T in debt but there is only a world money supply of $82T. Who here doesn't know you can't pay off debt with more debt? The system is a 400+ year-old scam. Lets turn this rig around. monetaryalliance.org
