One of my favourite blogs these days is Luz, combining a comic strip with great graphics and sustainability information, the author Claudia Davilla does a great job of hitting a single issue with each post.
The most recent post, (at this publishing date) is about Water Barrels, a thoughtful snapshot of the reality of seeing water as a resource to be used productively.
Check it out, I find the feed the easiest way to stay up to date.
