Earlier quoted context omitted.
The world has always been going down the toilet. The only difference now is that we have higher visibility of and lower tolerance for the bullshit. You shouldn’t be so pessimistic.
The other difference now is that we're pretty close to wiping out crucial ecosystems like the Amazon rainforest and show no signs of taking climate change as seriously as we should.
My point was that there is no “we” when we speak of humanity as a broad aggregate this way. There are specific constituencies—for instance, Bolsenaro and his supporters in Brazil—who are blocking the policies that most of us want to implement to stop climate change. It’s not “we” who are the problem, it’s “them”.
If you blame humanity in the aggregate you misdirect your energies and misidentify the solution.
The thing to do is to apply the appropriate political levers to weaken and oppose the constituencies who prioritize status-quo fossil-fuel energy policies over civilizational stability and the well-being of life on Earth. Blaming all of humanity is the equivalent of giving up and doing nothing, and makes the problem worse.
