Yes, dairy is better than meat. A great source for all this info is Our World in Data: ourworldindata.org/environmenta...

Environmental Impacts of Food Production

What are the environmental impacts of food production? How do we reduce the impacts of agriculture on the environment?

"Dairy better than meat"? Milk is mostly water, so seems better than other animal-based foods for GHG emissions but cheese is worse than pork or chicken for instance. Dairy is worse than most meat for air & water pollution (incl. eutrophication), for water use & more. Now bird flu rife in US dairy!

Thanks, my dairy farmer family in Wales also eat a lot of beef but that's another story...
