One big problem with individuals trying conservation on a farm or whatever is that we have very short lifespans, compared to ages of the species we're destroying. Something that's been around for a few million years of change versus 80 or so human years? We need institutions to step up, so conservation can have continuity. Otherwise, we're like ants trying to keep tortoises.
But we see institutions being cut back and destroyed, at the whim of the very people who are denying climate change policies. Eventually, we'll be just another endangered species ourselves, if we don't manage to protect habitats (from us).
Clearly, I have a cheerful world view!
