From the article: “But it would indeed be beneficial, for both climate and human health, if people in many rich countries consumed less meat, and if politics would create appropriate incentives to that effect.”
For the most part I now only eat meat, eggs, cheese, some nuts, and non-starchy vegetables. Mostly meat, and mostly very fatty meat like Pork belly. At 40 years old i've never been healthier as an adult - I don't buy the argument that meat is bad for you.
