Well. Man has contributed certainly. But there's something bigger going on old friend! And where not to blame. All governments have made seed vaults for a larger reason. In the mean time they made up a carbon tax and you better believe that money is in the seed vaults as well. The whole solar system is warming at the same rate. I can't tell enough people about this blatant world wide scam! There's tons of data from many agencies abroad all around the world that prove all planets are warming at the same rate! In the mean the there scamming g us with majority ignorance. The shitty thing is, the I go from the world's top scientists has been there for many years disproving g this governmental scam. I remember in school there was a big push for alternative energy in the seventies when we had the gas crunch.according to the lefties back then, we only had enough oil to last untill the 90's. Boy were they wrong!
