Forests … are in fact the world’s air-conditioning system-the very lungs of the planet-and help to store the largest body of freshwater on the planet … essential to produce food for our planet’s growing population. The rainforests of the world also provide the livelihoods of more than a billion of the poorest people on this Earth… In simple terms, the rainforests, which encircle the world, are our very life-support system-and we are on the verge of switching it off.
