Sustainability comprises a myriad of factors: greenhouse gas emissions, non-renewable energy and minerals, freshwater consumption, land use, ecosystem quality, waste, and nutrition.

Based upon these factors, general recommendations for a more sustainable diet include replacing animal protein with plant protein, eating a nutritious diet, and reducing waste.

And dairy is pretty good, too.” Read more…
