Inktober day 17 : Ganges River Dolphin“Why they matter : The Ganges river dolphin is important because it is a reliable indicator of the health of the entire river ecosystem. The government of India declared it the National Aquatic Animal in 2009. Industrial, agricultural, and human pollution is a serious cause of habitat degradation. Each year, 9,000 tons of pesticides and 6 million tons of fertilizers are used in the vicinity of the river. High levels of pollution can directly kill prey species and dolphins, and completely destroy their habitat. As the top predator, river dolphins have been known to have high levels of persistent toxic chemicals in their bodies, which is likely to adversely affect their health.”source : @wwf -- source link
