Are there any reasons for hope?
Anyone? Anyone? Bueller?
I see none at all frankly.
Now that's not to say that unreasoning hope oughtn't to continue but its important to acknowledge the irrationality.
There aren't really any indications that the anthropogenic destabilization of our planet's atmosphere is going to be addressed with anything even remotely like the urgency required.
There are the same number of indications that the christ-deluded western world is thinking rationally in regards to the mohammed-deluded eastern world. Or vice versa. (Death threats sure to follow I'm sure - don't bother, I'm alive and that's quite enough of a threat.)
On the economic front there's no indication that capitalism's market growth model shows any signs of correcting it's gigantic destructive failure.
Welcome to the hand basket.
