Ganges river is the largest river in India, and home of many unique ecosystems. However these ecosystems could soon come under great threat because rising sea levels are causing salt water to flow into India's biggest river. This is happening because sea levels in some parts of the Bay of Bengal were rising at 3.14 mm annually against a global average of 2 mm, and if temperatures continue to rise not only Ganges will become more salty but also large number of population in Indian subcontinent will be severely hit with more frequent and more powerful natural disasters such as floods and storms, which will very likely result in more disease and more hunger.
Ganges river, the largest river in India, does not only have problem with pollution but is also becoming more salty because of sea levels rise.
Indian university in the city of Kolkata that published this study was very surprised with the discovery of the mangrove plants, a rare phenomenon along the Ganges river belt, that usually live 100 km (60 miles) away in the swampy Sundarban archipelago spread over a 26,000 sq km (10,000 sq mile) area on the world's largest delta region. They also spotted more saline water fish in the river as Ganges river is becoming more and more salty. It looks like Ganges river does not only have problem with pollution but also with salinity.
