An international initiative of bloggers known as “Blog Action Day” launched today, with the aim of uniting thousands of blogging voices, talking about one issue for one day. This year on Blog Action Day, which is slated for Oct. 15, 2007, bloggers will be discussing the environment.

Major blogs have signed up to participate, including Lifehacker, Dumb Little Man, Lifehack.org, Get Rich Slowly, Web Worker Daily, GigaOm, The Simple Dollar, Zen Habits, Freelance Switch, LifeClever, Unclutterer, Pronet Advertising, Wise Bread and many more.

“For just one day, we’d like to unite as many of the millions of bloggers around the world and speak about one issue – the environment,” said Collis Ta’eed, an Australian blogger from FreelanceSwitch.com, and a cofounder of Blog Action Day. “We want to display the potential and the power of the blogging community, which is a disparate community but one with an amazing size, breadth and diversity. By bringing everyone together for one day, we can see just how much can be achieved, and how much we can be heard.”
