A tip to c h a n d r a s u t r a for getting the conversation rolling.
Yes. Environmentalists blog. However, a really good blog is a reflection personal views and thought processess, an online think space, etc. The environmental group blogs are nice tools (GreenPeace) for giving voice to members and ways to create volume around core messages. I have run across thousands of blogs that hit on clean air, water, river quality, birding, campaigning, health, labor and justice issues but the fun blogs are more personal and I don't think the movement (organizations) are comfortable letting staff kick out personal opinions on subjects just yet so most likely you are going to see more personal blogs (like this one) that are cranked out by environmentalists but not branded as such.
Keep the list rolling and links from comments will be pulled together into the list:
