This will be a quick post. This table, from several on the BBC website this morning, shows the impact of different food sources on the composition of atmospheric air. Making good food choices is healthier for my body and healthier for the planet and therefore healthier for everyone.
Depending on whether you are a Flat Earther, Donald Trump or an average human being you can decide whether this is a significant factor in global warming.
The one table I have extracted makes the case that even if I were not to give up meat completely but did reduce or eliminate beef from my diet, I would be making a small difference.
