People ask me often “what is the greatest thing I can do to end global climate change?”  My answer is the same as it is when people ask me “what is the greatest thing I can do to have a good relationship?”  The answer is to end the zero sum game.  In this case, it is to end the zero sum game with the earth.  Ask yourself, where in my life am I winning and by winning, some part of the environment is losing?  How can I make it a win-win instead?
