Animal rights activists have done stellar work in foregrounding the question of creature-consciousness: no meat-eater is now ignorant of the fact that their food once lived, breathed, maybe nuzzled its kin in a blood-soaked slaughterhouse. Environmentalists have a harder go of it. Fracking footage will always be less upsetting than your average fast food expose: Plants, after all, can’t wail frantically as they’re mowed down by the millions. But does that mean they’re not conscious? Is it sensible, or desirable, to start anthropomorphizing crabgrass and dandelions, or are plants really as insensitive as we all instinctively assume?
