It's nearly Earth Day, and Mother is calling. More than ever, she needs our help.
Remember that little global warming problem? Turns out that the food sector is responsible for about one-third of those greenhouse gases.
Thanks to a new tool called Life Cycle Analysis, scientists can pinpoint much more precisely what foods produce those climate-warming gases, and what stage in their "life cycle" is most carbon-intensive. Hint: There's more to it than transportation, or food miles traveled.
The results show some clear steps all of us can take to a more climate-friendly diet.
