Invited: classic environmentalists, anti-environmentalists, ecomodernists, deep ecologists, primitivists, luddites, nu-environmentalists, transcendalists, gaians, etc.
I consider myself a nu-environmentalist, however not an ecomodernist. Here is the nu-environmentalist starter pack:
Entry level:
The Rambunctious Garden - Emma Marris
Where Do Camels Belong? - Ken Thompson
The New Nature - Tim Low
Fully radical level:
The Balance of Nature: Ecology's Enduring Myth - John C. Kricher
The New Wild - Fred Pearce
Inheritors of the Earth - Chris D. Thomas
Accompanying literature:
The Mushroom at the End of the World - Anna Lowenhaupt Tsing
A Tree Grows in Brooklyn - Betty Smith
Basically, nu-environmentalists embrace non-native species and novel ecosystems, which arise from these species but also due to humans, like urban areas. Of course, even nu-environmentalists see the need to combat monocultures but they differ with the traditional environmentalists that original and untouched ecosystems are of higher value, and that such untouched ecosystems even still exist.
