The Yangtze River, China's longest waterway, once faced a severe biodiversity crisis after decades of overfishing. But five years into an unprecedented 10-year fishing ban, scientists are seeing surprising signs of ecological recovery.

Can one of the world's longest rivers truly heal? Climate Watch host Zhao Ying speaks with Chen Yushun, co-author of a new Science study on the Yangtze's recovery. Prof. Chen is from the Institute of Hydrobiology at the Chinese Academy of Sciences and Dean of the School of Life and Health Sciences, Hunan University of Science and Technology.
