This Ramadan, eat less meat to fight global warming and worldwide grain shortage

The UK Guardian has a story today on a senior UN figure advising people to eat less meat as an easy way for individuals to make a difference to climate change.
What's not mentioned is that hundreds of millions of people around the world are currently at risk of hunger due to record high grain prices. Of course, much of the current high price of grain is due to subsidies for US farmers to turn corn into ethanol; but that's a new development. But the harsh fact of the world food supply for the last few decades is that most of the grain being produced has been used to feed livestock, not people. A small reduction in meat consumption would result in far lower prices of staple foods such as rice and wheat.
Something to think about for those of us who have highly carnivorous tendencies at this time of year.
