I was listening to Leonardo tonight and it just made me cringe. The guy is a good actor, but fuck, you do NOT understand the mechanisms that change global climate! And as such, don't run your mouth about it! It reminds me of Rosie o'donnell talking about the gulf war when in all reality she probably couldn't find Iraq on a map or name the two main factions in said country. The sad part is that these stars are more often than not sending out miss information that pretty much all young people will take as fact.
