CO2's

I think we should pump more and more CO2 in the air. The more CO2 in the air, the better plants and trees grow. The better they grow, the more food there is. The more food there is, the less starvation occurring. Sounds like an idea. There is no evidence to prove that a rise in CO2 causes more ice melt. Even if it did, maybe beaches on Greenland wouldn't be so bad afterall. Some polar bears might die but more tropical fish would thrive. Just some thoughts...
