Deforestation

Global Forest Watch is a way to track deforestation worldwide.  Fifty soccer fields per minute for the past 13 years.

Update (November 19, 2019):  Deforestation in the Amazon was the highest in a decade last year at nearly 3800 square miles. That was a 30 percent increase over the previous year. The figure doesn't even include the damage from this year's fires.

Update (November 24, 2019):  A paper published in Science Advances notes that "full carbon accounting requires the consideration of forgone carbon sequestration, selective logging, edge effects, and defaunation". This meant that the total calculated carbon impact of clearing intact forests increased by over six times.
