This present mess is at base the gift of Lee Strasberg who had no use for audiences. They were more or less a necessary evil that allowed him to keep playing his stupid game.
In the area of world worry, you say " We've made the world an awful mess, and our whole civilization has started to seem like a worn-out machine that's about to break down." I would replace the word "civilization" with the word "species." Overpopulation will soon destroy us if we don't make the grand leap forward to taking direct responsibility as humans and not just pro-creation crazy animals.
