When we, humans, use ourselves as a measuring stick against which everything else in world is evaluated, then an anthropomorphic image of sentience and intelligence comes to govern our ethics. True: the life of plants resembles our living patterns to a lesser extent than the life of animals. But to use this as a cornerstone of ethics and a justification for rejecting the moral claim plants have on us is a case of extreme speciesism.That's right: "speciesism." You not only can't wear furs, but now you have to be nice to plants. We're all related way back, after all.
Rocks for dinner anyone?
