Well then I suspect you don't see much of anything. It's happening before your eyes and you don't see it? Do you see genocide in Palestine? Do you see fascism in America? Do you see plastic trash in waterways? Do you see homelessness? Do you see the rich getting richer and the poor getting poorer? How do you not see the obvious outcome? The only reason we're still making enough food, is because of petroleum based fertilizer. Without that, we'd have lost billions of people already, or they never would have been born in the first place. That's unsustainable. And as society breaks down, so does the economy that allowed those fertilizers to exist. Billions die, any way you look at it, billions die and civilization crumbles. Which happens first doesn't really matter.
