The Democratic Convention meeting in Denver is going green. A Boulder-based company is donating more than 70,000 hotel keys made from biodegradable wooden keys -- in place of the plastic versions.

Apparently, this will be good for the environment. A few questions come to mind. Aren't all trees biodegrable?

And how many trees did they have to cut down to make those keys?

The company says if hotels around the nation followed Denver's lead, it could reduce plastic waste by 1,300 tons a year.

I wonder what they're going to do with the toilet paper? How about biodegradable corn cobs?

Just in case, I'm packing Charmin eight-pack in my carry-on luggage.
