 Ed drenches Fatima’s prized cactus in pesticides without permission. This is uncontroversially wrongful but only uncontroversial because the cactus is Fatima’s. If a cactus grows in Ed’s yard and, purely for fun, she drenches it in pesticides, killing it, is that wrong? There is a family of unorthodox but increasingly common ideas about the treatment of plants according to which any killing of plants is at least pro tanto wrongful and that treating them as mere tools is too (Marder 2013; Stone 1972, Goodpaster 1978, and Varner 1998 are earlier discussions and Tinker 2015 discusses much earlier discussions). One natural way to develop this thought is that it is wrong to treat plants this way simply because of the effects on plants themselves. An alternative is wrong to treat the plants this way simply because of its effects on the biosphere. In both cases, we can do intrinsic wrong to non-sentient creatures.
