A couple good points came out of a talk by SustainLane's Warren Karlenzig at the Commonwealth club last week. He was talking about Green Economies (sustainable) versus Grey Economies (unsustainable), and pointed out that California responded to the melting freeway by offering a day of free public transit. "What would governor of Arizona do in a similar situation: offer free gas to everyone?"

Ouch. Take that, Governor Janet Napolitano! But it wasn't all Grand-Canyon-State-bashing; Warren's speech touched on the ways that companies can keep themselves in business -- and the planet inhabitable -- by using clean fuels, non-toxic local foods, and mixed-use zoning that lets you shop and live and work without commuting hundreds of miles. Take a look at his speech, and check out How Green is Your City, an ecologist's dream of Earth-friendliness. Hopefully that vision's more prescience than paleo-futurism.
