Here’s an interesting news item I rediscovered in the NYtimes today: raising animals for meat releases more CO2 into the atmosphere than does the entire travel industry combined. This is based on research conducted by the Food and Agriculture Organization of the United Nations. I’m sure some of my regular readers will take issue with this, but it is kind of intriguing. Add to that the growing evidence that vegetarianism is a pretty healthy diet (possibly not the healthiest – a small amount of meat may actually be slightly healthier; see references below) and the connection to IQ (though not causal) and things are looking up for vegetarianism. Maybe this is just confirmation bias, as we all have a tendency to look for evidence to support the things we believe/want to believe. But some of this is also pretty good science. Anyway, here are the references:
