When people flirt with despair about the future, they are less likely to take the actions necessary to safeguard it, focusing instead on the short-term.

The cumulative amount of man-made global pollution that's in the atmosphere now traps as much extra heat energy every day as would be released by 400,000 Hiroshima-class atomic bombs exploding every day. It's a big planet, but that's an awful lot of energy.
