The New Normal

“No one is sure how much of Earth is covered by novel ecosystems, but Erle Ellis, a map specialist at the University of Maryland, has taken a stab at quantifying it. Defining novel ecosystems as “lands without agricultural or urban use embedded within agricultural and urban regions,” Ellis estimates that at least 35 percent of the globe is covered with them. Their share of the planet will probably expand, and many ecologists think that these novel ecosystems are worthy of study and, in some cases, protection.”
