There's a folk view that I sometimes round off as "deep ecology," though I think it extends to more than the academic definition[1]. Roughly speaking, tenets include:
1) Ecosystems have an inherent right to exist, and have value beyond aggregating individuals' preferences or happiness.
2) *Species survival* is a coherent concept, and preserving current biodiversity is a worthy goal not just instrumentally but as an end in itself.
3) Humans are bad.
4) Ecosystems are by default in equilibrium.
5) Nature and her children were in harmony before some subset of {white people, capitalism, industrial revolution, agricultural revolution, homo sapiens, great apes} fucked it up.
6) The "Earth" will in a meaningful sense be better off without humans.

I think a lot of these points are not just wrong but incoherent (especially 4 and 5, but I think to some degree or the other, the remaining points rest on those). Is there a clear writeup of what deep ecology entails and why it's wrong? (The arguments on wikipedia seem noncentral).
Thanks!
I personally would disagree that variety of experience is morally relevant. Obviously, most people enjoy variety of their own experiences, but that's already waded into the total hedonistic utilitarian equation because it makes us happier. So I don't think that we need to add it as a separate thing that has intrinsic moral value. Looking at diversity can also be aesthetically pleasing for us, but that gets waited in to the equation because it makes us happy, and so, again, I don't think we need to say it has intrinsic moral value. I don't think our aesthetic appreciation of biodiversity is a very significant source of happiness, though, compared to the well-being of the much larger number of animals involved.
I think what you said makes sense given that moral position. I haven't heard a name for the position that diversity of experience is intrinsically morally significant, but I have a friend who I think argued for a similar position, and I'll ask him.
