The Boreal Forest - Mother Nature's shop vac (WFP)

1,500 of the world's leading environmental scientists say that we need a new chorus, one aimed at cleaning up the mess that's already been made.

It goes something like this: replenish, repair, rejuvenate. Until now, these words have been the silent refrain of Mother Nature as she soaks up, washes away and regenerates our air, water and soil. (And who else but your mother would dedicate herself to cleaning up such a monumental mess without a fuss?)
