Treehugger has this story about a Chinese project to clean up one of that country's polluted rivers: http://www.treehugger.com/files/2009/01/chinese-tower-cleans-river.php When last I remembered, the most polluted river in the world happened to be India's holiest - the Ganga. I remember Indian politicians from Indira Gandhi down claiming that they were going to clean it up. Forty years on, little, if anything, has happened other than ever louder claims being put forward as is done in India's Parliament and State Assemblies especially as far as the environment is concerned. My friend Mohan and I have discussed the sorry state of a much smaller "river" that runs through our home town - the Couum on this blog earlier.
I wonder if this is a time for the Govt of India to seriously get off their collective haunches and look at converting the filth that goes into the rivers into a valuable resource - which it most certainly is? The huge amount of sewage that goes out into India's rivers could be processed into biogas and used as a fuel and the slurry left behind processed into fertilizer. India imports crude oil as a fuel and also buys natural gas for its huge fertilizer industry. And the politicians have not bothered to look closer home for the resources that are directly available.
Hopefully, these days when the country keeps talking about competing with China, it would look at the better things that the Chinese are doing and not just emulate the worst that comes out of that country.
