Threats to the World's Largest Lakes
June 08, 2015This map depicts the world’s largest 20 lakes by surface area. The lakes are divided into four categories based on the biggest threat they face—pollution, climate change, declining water levels, or declining fish stocks.
The categories reflect what was judged to be the primary threat to the lake, as determined by a Circle of Blue analysis of media reports and scientific studies. Most lakes, however, suffer from a combination of problems. Click on a lake locator dot to learn more about that lake’s specific challenges.
