Our World in Data articles are always interesting to look at, partly just to see how they visualize data. We also know (at at least I think it is clear) that eating less meat is a key way to reduce our species’ ecological footprint. In the UK, which is probably a reasonable indicator for a range of Anglo-American and European countries, meat eating has declined over time and younger people tend to eat less meat. Around 80% of retirees eat a traditional amount of meat, but only about 50% of young adults (18-24) do.
