i am not a vegetarian, but i care about greenhouse gas emissions, so it looks like i should eat less meat.  the bbc issued a report this week showing that livestock are responsible for an astonishing 18 percent of all global warming gases!

so try to remove meat and/or dairy from one meal per day, and if that is too much try once or twice a week, and make sure to never buy meat that you let go to waste; a quarter of all the food that is produced goes uneaten.
