Non-vegitarian is responsible for global warming?

I think probably the scientist was referring to the amount of methane gas produced by animals, mainly cattle, when they burp. Apparently it is a huge amount worldwide and is contributing to the greenhouse gases. If more people were vebetarian there would be less cattle, but they are trying to find ways of feeding cattle more digestible food to reduce the gas.

It is somewhat responsible for global warming. But nuclear power, and technology as a whole should take much of the blame for global warming. Certain industries are far guiltier for global warming than the gases that cattle produce. The biggest offender, much bigger than non-vegetarians, would be major corporations that send all kind of pollutions into our atmosphere...but that's just my opinion.

Actually the original contribution by humans to global warming started thousands of years ago when man started up rice paddies in a certain part of the world that gave off methan which is a worse global warming gas than carbon dioxide but is not produced the quantities that carbon dioxide is today by coal fed electric plants. Of course there would have been fewer coal plants, in the U.S. at least, if extreme environmentalists hadn't just about stopped the building of nuclear energy plants around thirty years ago.
