Coming soon... MNN will feature a new guest columnist each day. These contributors will be newsmakers and notables from the eco-community. Check back soon to see who they are and what they have to say.

In the meantime, catch up on the latest environmental news of note with our daily Green News Roundup blog. It's must-read material each morning.
