Fuck that. It's never lost, it's just that we are constantly heading towards worse outcomes.
If we as humanity start taking it seriously tomorrow, it would still be a victory over only starting in a decade.
It's not lost, it's just getting worse, and that should make people want to fight.
saying that the fight is lost is just creating more disengagement and hopelessness.
I like the saying "The best time to plant a tree was 30 years ago, the second best is today." Because it is almost universally true about any long term goal.
