Causes: American Proverb

When all the trees have been cut down,
when all the animals have been hunted,
when all the waters are polluted,
when all the air is unsafe to breathe,
only then will you discover you cannot eat money.

This is good shit, believe in it. Not a real 'Cause' I know, but if you followed the message it gives, you'd be doing better than any current cause.
