Scientists Say: Plastisphere
As plastic floats in the ocean, it can acquire its own colony of microbes and algae. We call this ecosystem the plastisphere.

Earth’s tectonic plates won’t slide forever
Earth’s surface morphs, owing to the movement of its tectonic plates. But those plates didn’t use to move so quickly. And in a few billion years they’ll grind to a halt, new research suggests.
