Something everyone can do to help the environment is lower their total consumption of animal foods. Factory farming produces 18% of the worlds greenhouse gases, including large amounts of methane which is 23 times worse than CO2, and large amounts of nitrous oxide which is 300x worse than CO2.
This paper from the FAO pegs livestock as a bigger contributor to global warming than transportation and calls for meat consumption to be cut in half. Of course, this may fall on deaf ears on a bacon-centric board. I've been a vegetarian for 3 years and it's not nearly as bad as some would have you believe. It's one of the best things you can do for yourself, the Earth, and last but not least, the poor animals.
