The Cows Didn't Do It !

The UK Telegraph posted an article yesterday reporting that grazing cows and sheep may not contribute to global warming.  A recent study in China showed that cows grazing in China actually reduced nitrous oxide, another greenhouse gas.  The Authors of the study said that this does not mean that producing livestock to eat is good for the environment in all countries, but that in certain circumstances, letting cattle graze can be good for the environment.  Most of the article attempts to explain why these studies do not mean that it's ok to eat red meat.  I posted this to make one point--we really don't know as much as we think we do about global warming and what causes it.  Meanwhile, we really don't understand how much of climate change is natural cycles in the life of the planet.  I will continue to eat steak.
