The digital revolution has changed environmental activism. Instead of taking it to the streets people are moving online. While there's still a place for door knocking and protest rallies, more and more causes are going virtual.

StopGlobalWarming.org is a good example. Laurie David, producer of Al Gore's movie on climate change, An Inconvenient Truth, began a virtual march to stop global warming. The march is now 600,000 people strong and growing every day. In addition to showing your support for solutions to climate change, you can also choose who you want to "march" with. Pick a celeb like Sheryl Crow or Leonardo DiCaprio, or pick a politician. (I'm guessing 2008 presidential candidates Barack Obama and Hillary Clinton are the new favorites.)

And speaking of politicians, you can take the good old fashioned writing to your elected officials online. Believe it or not, the government makes it easy to find the information to send an e-mail to your senator, or congress person, or other elected representative. The websites for the US House of representatives and the US Senate have up to date listings. USA.gov includes a comprehensive listing of state level representatives.

Or if you'd prefer someone else to do the writing there are organizations like Environmental Action that make it really easy. They have a whole listing of action items. Right now they're asking the Environmental Protection Agency (EPA) to keep America safe from lead; asking Wal-Mart to sponsor a free energy efficient light bulb day; and asking elected officials to save the polar bear. All you have to do is click the cause and "sign" a pre-made letter. That's it.

And for those who still want to go out and get a little dirty, activist Bill McKibben is calling on America to "Step it Up" on April 14 (recently featured on GO). McKibben is using the internet to organize and spread the word of this grassroots movement to fight climate change.

This new wave of environmental activism has definitely taken on new forms. Mark Spellun, Editor-in-Chief of Plenty Magazine wrote in the June/July 2006 issue, "Indeed, just because there aren't protests in the street doesn't mean that there isn't a revolution afoot. Forward-thinking individuals have integrated green living into their daily lives and their pocketbooks, creating solutions to problems that can't be solved by a march or a sit-in."

At Green Options we'll do our best to feature the many ways that we as individuals can make a difference - both online and off.
