In my 1992 FoxSense series of environmental graphics (cartoons), I offered several related to wildlife conservation and wildlife values.
This one, as it applies to large, free-ranging carnivores, proposes a challenge to humanity, with its ever increasing demands on Nature, to live in such a way that we can not only let 'em be (leave them alone with enough space to be the animals they have evolved to be) but also to let 'em BE (continue to exist at all).
