Fresh water crisis - The forgotten battle of environmentalists

Karen Street has encouraged me to write on the fresh water crisis, and has kindly hosted the post on her blog. 

... Water conservation and prevention of water pollution were one of the earliest battles of environmentalists - much before climate change was ever heard of. Though they have become the green equivalents of 80s fashion, these battles are as relevant today as they were ever. In fact, fresh water is the most important battle in the war against global warming. 

Fresh water is the elixir of life. The entire bio eco-system is based on this. Any minor disturbances to the supply of fresh water will have catastrophic impacts on biodiversity. The scariest effects of climate change are not rising sea levels or massive tornadoes, as exemplified by films such as The Day after Tomorrow. Scary though they might be, there are scarier problems : desertification of rainforests, severe droughts, drying river beds due to melting glaciers...

Karen has helped me a lot in the writing, in proof reading the essay, and in searching for the right images to explain the story. Thanks a bunch, Karen, for all the motivation you gave me. 

Karen is a committed environmentalist, and writes very informative essays on the climate change problem. I hope you people visit her blog to learn more about these pressing issues.
