The good news is that simply by making some changes to your diet, by adopting what is known as a “planet-friendly” diet, it is possible to contribute to the solution to climate change. It’s merely a question of knowing which foods are the worst climate offenders, and then either transitioning away from these foods or replacing them altogether with climate-friendlier alternatives.
According to the World Resources Institute, far and away the most destructive food is beef. In terms of all three markers — greenhouse gas emissions, freshwater consumption, and land use — beef is an environmental disaster. Just behind beef is dairy, followed by poultry, pork, eggs, and fish.
The United Nations Intergovernmental Panel on Climate Change (IPCC) proposes that people reduce their consumption of animal products by 30% as an urgent component of their recommendations to combat climate change.
About a year ago, I gave up red meat for exactly this reason, with less than perfect success. Old habits are hard to break, and change comes slowly and requires patience.
