Some estimates put the cost of rebuilding the city and its neighbors at $150 billion -- seven times more than the total amount the feds spent on the nation's 10 most expensive previous natural disasters. Eco New Orleans would cost even more, take longer, and require forming a plethora of public-private enterprises and overcoming immense ideological obstacles. But if we as Americans are unwilling to spend the time and money to rebuild New Orleans and the rest of the Gulf Coast with environmental concerns taking a front seat, then we're as self-interestedly myopic as the administration that couldn't pry itself out of vacation mode to save people's lives.
