It’s no secret that humans—noisy, messy creatures that we are—are vastly altering Earth’s environments. But it’s one thing to know this in the abstract, and another to see global changes laid out in detail, as they are in comprehensive new maps published this month in the International Journal of Applied Earth Observation and Geoinformation .

The most common change was forest loss due to agricultural development, and the second most common was the reverse—farms to forests. The swift urbanization of grasslands, forests, and farms was also reflected in the maps.
