Prior to Katrina, the South Bronx and New Orleans' Ninth Ward had a lot in common. Both were largely populated by poor people of color, both hotbeds of cultural innovation: think hip-hop and jazz. Both are waterfront communities that host both industries and residents in close proximity of one another.

We need to work together to embrace and repair our land, repair our power systems, and repair ourselves. It's time to stop building the shopping malls, the prisons, the stadiums, and other tributes to all of our collective failures.
