Quoted from hAbO:Its a little bit of a pessimistic view but I don't believe everyone on the planet will be able to move away from using dirty energy sources fast enough. Were already seeing drastic climatic change with extreme weather events. How bad will it have to get before people realize we need to change? I remember a quote from Michael Crichton's Lost World - Its not save the planet but save us. We may be the ones responsible for our own extinction.
