Satellite imagery reveals a green, breathing planet—but one under threat from human activity.
We call Earth the “blue planet” with reason—water covers 71% of our world’s surface, a fact that sets the third rock from the sun apart. But humans are land creatures, and we have lived and thrived on Earth because of the vegetation our planet supports. We depend on the green.
Now recent footage gathered by a National Oceanic and Atmospheric Administration (NOAA) satellite shows in detail just how that green changes over the course of the seasons—and how we’re altering it with man-made activity.
