Not a terrible "documentary" really...But I was blown away that Gore spent an hour and a half talking about the dangers of increased CO2 in the atmosphere, but barely talks about the main SOURCES of CO2 and other greenhouse gases around the world.He mentions burning coal in passing, but doesn't even touch on the fact that cattle farms around the world are ENORMOUS contributors of CO2 and methane (in fact, they are the source of 18% of all greenhouse gases). Cattle farms also have a huge impact on water quality world-wide.(Read the recent United Nations Food and Agriculture Organization report, if you want to learn more.)If Gore truly believed his own theories, he would be a militant vegan. And he certainly wouldn't fly in private planes or own 5 enormous homes.But Gore's not a vegan. He wants to be president. That means winning votes in cattle country. The evironmental movement is just a stepping stone for him.Hypocrite!
