In the science journal Nature this week, a piece was co-authored by more than 200 scientists from around the world—a veritable who’s-who of researchers from the world of tropical forest ecology.

The gist of the paper is alarming:

  1. The rapid disruption of tropical forests worldwide probably imperils global biodiversity more than any other force today.
  2. The best hope lies in protected areas.
  3. Yet many protected areas are not effectively protecting biodiversity.

The authors write:

Our analysis reveals great variation in reserve ‘health:’ about half of all reserves have been effective or performed passably, but the rest are experiencing an erosion of biodiversity that is often alarmingly widespread taxonomically and functionally.
