A.M. Greenlist: Bicycles to polar bears*

Today's the last day of Bike to Work Week!

>> If your bicycle needs a post-week tuneup, check out "The Chainbreaker Bike Book," a new "seat-of-the-pants, low-budget ... do-it-yourself bike maintenance guide that keeps things simple, straightforward, and, most importantly, real," according to Keith Goetzman in Utne.

>> A bold water conservation plan's coming to L.A. The plan includes mandatory water-use restrictions on residents, changes in building codes, and waste water recycling programs. "Administration officials say the point is to act now so the city can meet increased demand through a combination of conservation and recycling. They note that Los Angeles is an arid metropolis that has grown by dipping long straws in far-flung water supplies."

>> Tokio Lounge in Hollywood's going to be reincarnated in green fashion as Ecco. The new lounge will be revamped using eco-friendly building materials and is set to reopen in July with an organic menu, LED lights, and waterless urinals.

>> Today's also Endangered Species Day. Celebrate the polar bears' newfound status as a threatened species -- though I suppose the fact that they're in danger is not actually an uplifting thought... A town called Churchill in Canada expects to see tourists flock to the town to see the polar bears while they still can. *(An earlier version of this item listed polar bears as an endangered species. In fact, the recent ruling gives the animal "threatened" status under the Endangered Species Act.)
