ganga_dolphin.jpgIt’s almost over but shouldn’t go unnoticed on the Mutiny. The river Indus, or the Sindhu, lent her name to a land and a people. Now, according to the World Wide Fund for Nature, she and her East-facing twin Ganga are dying:

Five of the ten rivers listed in the report are in Asia alone. They are the Yangtze, Mekong, Salween, Ganges and Indus…Even without warmer temperatures threatening to melt Himalayan glaciers, the Indus River faces scarcity due to over-extraction for agriculture. Fish populations, the main source of protein and overall life support systems for hundreds of thousands of communities worldwide, are also being threatened.(link)

In a report issued about dangers to 10 of the world’s great rivers, the WWF. Climate changes threatens the Ganges and especially the Indus with both a decrease in supply and the hazardous instability of sudden floods. The Indus basin more than 178 million people and draws as much of 80% of it’s water from Himalayan glaciers; the Ganges basin has atleast 200 million people (See Razib’s comment below). 60% of the tributaries of the Ganges are being diverted. Both rivers are the homes to their own special populations of rare freshwater dolphins—approximately 1100 Indus river dolphins and only a couple thousand Ganges Dolphins, as well as a very rare Ganges freshwater shark. The Ganges and Brahmaputra together span 10 biomes and water the last tiger inhabited mangroves. The report is available in PDF form and is well-written and well-foot-noted—it’s a concise set of geography lessons and worth reading on its own.

One of the loveliest things I ever saw in India was while crossing a branch of the Ganges in the West Bengal countryside—half a dozen dolphins jumping in coordinated arcs across the river, their tails flipping, backlit by the afternoon sun. I stood up in my amazement, rocking the boat, but I was suddenly unafraid—they were so delightful. I want my grandchildren to see them too.
