Much of this kind of attitude (where it can't substantiate claims concretely) is a type of fashionable nihilism masquerading as environmental concern. It serves as a kind of jaded virtue signalling too. This isn't to say that we shouldn't be worried about various aspects of the environment and human habits, or that we shouldn't individually and collectively push for better use of resources, but to simply claim we're lost as a species and discount all notions of us being capable of continuing to improve human well-being with better technology is both cheap and ignorant of centuries of real progress that have no reason for not being able to continue or improve in real ways..
