October 15, a week from today, is Blog Action Day, and the theme this year is the environment. If you have a blog and want to join in, all you have to do is use that day to post something related to the environment, in whatever way, shape, or form you prefer. You can pick an environmental issue that has meaning for you and let us know why it's important. Organize a beach or neighborhood cleanup and tell us about it. If you're into fiction writing, give us a story with an environmental theme. Have a podcast, videoblog, or photoblog? Join the fun! The idea here is to have a mass effect on public awareness by sharing as many ideas in as many ways as possible.If you're game for participating, go register your blog with the 7,000+ other blogs (with 5 million readers!) that are already signed up. Also, see the Blog Action Day blog for more on how bloggers can change the world.
