Red meat is more polluting than cars !

Some days ago I've posted a note "Should we eat strawberries in winter" with a conclusion that, regarding CO2 criteria, it's much better to avoid to eat red meat or dairy products than vegetables even if thought hey have traveled thousands of kilometers from the field to your plate.

As Cecilia noted in her comment to my post "red meat consumption is one of the biggest contributor to the greenhouse effect... and not for their transport but rather by cattle's own digestion... methane is 12 times more polluting than CO2 !"  

The Nobel Prize, Dr Rajendra Pachauri,  chair of the United Nations Intergovernmental Panel on Climate Change, had the same comment - related in The Guardian - that red meat accounts for 1/5th of the total global  greenhouse gas emission. Cow's flatulence methane is said to be 23 times more polluting than car's dioxide carbon !
