A periodic reminder that if you're concerned with climate/biodiversity issues, it's increasingly a waste of time to work on persuading skeptics and fatalists (who either eny it's happening or say it doesn't matter for philosophical reasons). Some are sincere,s ome are not, but the pursuit of persuasion and consensus is ultimately founded on the hope that the 'marketplace of ideas' will move to a new stable equilibrium; available evidence suggests that this may take longer than changes in the underlying conditions, such that the more effort you spend in arguing the worse worse the problem will get. I suggest it's better to pursue unilateral policy goals wherever possible.
