the problem is. If everyone gives up meat and not dairy. You're going to have the same methane-emission problems from cows.
I think they will realise this eventually. The biggest hurdle will be to make them give up the meat.

People will need to turn vegetarian if the world is to conquer climate change, according to a leading authority on global warming.
In an interview with The Times, Lord Stern of Brentford said: Meat is a wasteful use of water and creates a lot of greenhouse gases. It puts enormous pressure on the worlds resources. A vegetarian diet is better.
Direct emissions of methane from cows and pigs is a significant source of greenhouse gases. Methane is 23 times more powerful than carbon dioxide as a global warming gas.
