Don't eat factory-farmed meat. Wait--free-range food isn't what it's cracked up to be, either. Buy organic--or not. Local is greener. Except when it isn't.
To green, or not to green, that is the question--and how. Take any statement that sounds good and someone somewhere will prove it false (like I do, with GMOs). The fact that nobody has a clear environmental agenda only adds to this dilemma. It doesn't help that sometimes what's clear from an environmental point of view clashes with the morals of the matter. For instance, organically raised beef is better for the environment--at least, until you consider the massive increase in acreage involved.
But fear not, gentle readers! I offer you one key to all of your greening dilemmas--at least, when it comes to food:
Don't eat what you wouldn't kill.
In my mind, it essentially amounts to cowardice to do otherwise. Of course, most of us don't raise our own meat. So most of us don't know what it's like to kill something. For most of us, the idea never even crosses our minds, unless we get it vicariously from watching crime shows.
But ask yourself, what would you happily kill for dinner? I'm not talking about survival situations, where you're stuck in a deathscape with no chance of life unless you kill Fluffy (actually, if it gets to that point, Fluffy's probably killed you first). I'm talking about your everyday meals. Could you catch a chicken and lop off its head for lunch on Sunday? Would you butcher a pig so that you can enjoy a hot dog?
