Josh covered this already.
I think this comic can best be summed up by philosopher and Plugger, Ann Coulter:
God gave us the earth. We have dominion over the plants, the animals, the trees. God said, 'Earth is yours. Take it. Rape it. It's yours.'
I've got nothing more. The farmer's not living green, look at that exhaust! And a farmer lives in the middle of nowhere. It's damn hard to live green when it takes an hour to get to the local grocery store. But not even trying? Because those damn liberal commie hippies support it?
I hope he grows tomatoes.
ETA: Someone who knows something about environmentalism - isn't farming pretty far away from green? At least farming on a large scale? All the food for the cows or pigs, the preservation of the crops, all that takes energy in the form of land and gas and electricity and food that could go to humans. Or so I've heard.
ETA: He's from Texas! Why didn't I notice this the first time? And guess what? There's a base near Corpus Christi. There are liberals and environmentalists who are Texans or in the military, but since Pluggers live by stereotypes, so will I. His location is not surprising. Except CC is on the coast. And he has a farm? Hmm.
