A recent study found that the water of 70 percent of the 165 large lakes in China has become clearer in the past 20 years.
The study, conducted by scientists at the Chinese Academy of Sciences (CAS), observed and recorded the color and transparency variations of the worlds 1,049 large lakes and reservoirs with an area of 25 square kilometers or above between 2000 and 2018.
The water in 71 percent of the 165 Chinese lakes it monitored became clearer, with 36 percent having a remarkable change in terms of water clarity, said Zhang Bing, leader of the research team and a research fellow at CAS Aerospace Information Research Institute.
