Sadly, rising anthropogenic pressures from a human population now in excess of 400 million living within the Yangtze River watershed have taken its toll on the baiji (see Wang and Zhao‘s chapter 19). An influx of human sewage, construction explosives and mining have degraded the baiji‘s habitat. , 2007) and concomitantly, a reduction in the abundance of baiji prey. Unselective fishing methods including the use of rolling hooks, electrofishing gear and gillnets have had direct and dire consequences for the baiji as well.
