What would happen if the world’s trees disappeared?

“Even a single, isolated tree in an open area can act as a biodiversity ‘magnet,’ attracting and providing resources for many animals and plants,” Prevedello says. “Therefore, losing even individual trees can severely impact biodiversity locally.” The loss of trees from the world would throw the climate off kilter (Credit: Getty Images)

What would happen if you set off every volcano in the world?
