Earth Day falls on Tuesday, April 22 this year and we'll be following a lot of the goings on.

For starters, Wikipedia is a good place to visit for a primer. The EPA also has a nice little resource site.

The New York Times is dedicating its Sunday Magazine to green issues (it's 'Invent' section is of particular interest to geeks). The Washington Post has advice from some notables.

And last year, we had a couple of posts (here, here, here, here and here). We'll have more this year, so check back. If you see something that deserves some attention, especially tech related, leave a comment!

Update: This AP report on Wired informs us that 18 states aren't taking climate change sitting down. Go NY/NJ!
