Half of world's lakes are less resilient to disturbance than they used to be

Nearly half of the world's large lakes have lost resilience, or the ability to bounce back after an abrupt disturbance, in recent decades, according to the first global assessment of long-term changes in lake resilience. Lakes in eastern North America and northern Europe have been hit the hardest, and dense populations and pollution are largely to blame, the study suggests. However, wealthier regions had healthier lakes, suggesting costly conservation efforts may pay off.
