Your Questions About Food and Climate Change, Answered – The New York Times
Modern agriculture inevitably contributes to climate change, but some foods have a bigger impact than others. Beef, lamb and cheese tend to do the most climate damage. Pork, chicken and eggs are in the middle. Plants of all kinds typically have the lowest impact.
What you eat matters a lot more than whether it’s local or organic, or what kind of bag you use to carry it home from the store.
You don’t have to give up meat altogether to make a difference. Even smaller shifts, like eating less meat and more plants, or switching from beef to chicken, can reduce your climate footprint.
One simple way to cut your food-related emissions is to waste less. Buying what you need and actually eating it — instead of tossing it out — means that the energy used to produce your food has been spent efficiently.
