This is just a correlation, not a causation.

The real factor influencing life expectancy is likely going to be wealth. Poor countries have little/expensive meat and a low life expectancy. Rich countries have much/cheap meat and a medium life expectancy. And wealthy people in rich countries will have the highest life expectancy, even though they're more likely to eat a vegan diet compared to the poorer people in those countries.

As a result, if you look at it globally, on average, people with a high life expectation are eating tons of meat. But if you look at just rich countries, people with a high life expectancy are eating less meat.

And if you're thinking, the green people are faking studies, consider for a moment, if we would really deem life expectancy worthwhile, with the planet getting gradually less worth living on from here on out.

Even they say that meat is not necessary and can be substituted: “Studies looking into the diets of wealthy, highly educated communities, are looking at people who have the purchasing power and the knowledge to select plant-based diets that access the full nutrients normally contained in meat. Essentially, they have replaced meat with all the same nutrition meat provides.”
