What if millions of people talked about a single topic of importance on the same day?

That’s the premise of Blog Action Day, an annual event hosted by Change.org held every October 15, that “unites the world’s bloggers in posting about the same issue on the same day with the aim of sparking a global discussion and driving collective action.”

The theme of Blog Action Day’s first year was the environment.  In 2008 it was poverty and last year it was climate change, when over 13,000 bloggers participated from over 150 countries.

This year’s theme is water, because as Change.org says, “Access to clean water is not just a human rights issue. It’s an environmental issue. An animal welfare issue. A sustainability issue. Water is a global issue, and it affects all of us.”

Among the topics people will be talking about are water footprints, water as a human right, the bottle water industry, water wars, and conservation techniques.  If you are a blogger, go to Blog Action Day for more ideas.

Or check in here at Ecolocalizer, where we will be running posts on water issues all week.  We will be focusing on water conservation, our national water infrastructure, and privatization of water resources and systems.  We will also be highlighting local actions communities are taking to ensure access and ownership of their fresh water.

Follow Blog Action Day on Twitter @blogactionday and hashtag #bad10.
