The thing is that logic, reason, and numbers don't convince people, even intelligent people. It's just the same dumb shit that does convince people: what are my friends doing, what are other people my age/race/gender/nationality doing, what does soandso authority figure who i like think of said subject, how can i rationalize my past behavior or reconcile it with my other beliefs, etc. When you approach people directly with an opposing viewpoint and valid reasons you're going to get rebuffed. It's all about going about it in an indirect way and making the other person(s) feel like they figured it out on their own.
Meatatarian society (which I am guilty in participating in) will probably die off at some point since it's just not sustainable, the only question is how bad will the effects be on the environment before anything meaninful changes.
Also nutritional science is very young in relation to how old human society is, and what is considered good nutrition v. bad nutrition changes depending on the source. In 100 years when we have a lot more data to work with on long term health effects and nutritional sources I think we'll get a better view of what, exactly, would be an ideal human diet. Maybe in like 10-20 years google can start collecting data on exact environmental conditions for people as they develop, and better measurements on what foods are being consumed to allow better regressional type analysis.
