Producing and eating less meat, especially red meat (cow, sheep, goat, and pig) is a very effective way to reduce the carbon footprint of the world. In fact, eating less meat might be the easiest way for you as a person to have a positive impact on your health and the world.
The scientific evidence supporting the claim that eating meat is bad for the planet is quite overwhelming. This video summarizes them in an understandable way.
If you are not ready to give up red meat, you can replace high-carbon red meat with low carbon alternatives as well. (Find out more about that here.) Or choose one day every week as your veggie-day and build up new habits from there.
The most important step you can take is to talk about it. What do you serve when you entertain? What do they serve at the company cafeteria or at your kids’ school? The system of cheap meat is far more expensive than most of us realize.
