These two things are intrinsically tied in practice. The utopia where well cared for animals feed 8 billion people does not exist, and cannot exist without many more earths.

Try going vegan for say... a year. Make it a fun game. You get to try out some new foods and restaurants! You can always start eating meat again if you decide you want to take part in the stuff you saw watching Dominion.

You don't even have to give up pedantic moral discussions and infighting (i.e. the distinction between "fucked up" and "immoral"). Those are deeply entrenched traditions in the vegan community!
