Dear Sirs, To fight global warming, have the United Nations create 'The Global 50/50 Lottery', the world's first honest global lottery, to raise the massive funds needed to buy clean electricity generating wind, solar, ocean and water systems, to replace the electricity from our coal burning electric power plants, which are emitting the carbon dioxide that is causing global warming. Remember, human greed is like a force of nature that can move mountains. If we can exploit it to fight global warming, we just might beat it!
