Our take: In the last 15 years, a lot of evidence has shown that rapid ecological changes are under way as result of how civilization has stressed the environment. These changes could change the way the ecology in the world reacts for generations to come.
Is the world doomed? Well, not exactly. But the world we know may be heading toward a series of irreversible ecological tipping points that will render it unrecognizable, according to a new study out in Nature with the understated title Approaching a state shift in Earths biosphere (behind a paywall, unfortunately).
An interdisciplinary group of scientists analyzed dozens of studies documenting rapid ecosystem changes from the past and already underway. The basic takeaway: ecosystems can change quickly, and irreversibly, on small scales and large. Over the past 10,000 years the rise of civilization has put unprecedented stresses on global ecosystems.
