The recent oil spill in the gulf of Mexico is a cautionary tale. As we worriedly watch aerial photos, we imagine places closer to us, in the same scenario. The oil well off the coast of Louisiana exploded a week ago [see NY Times article]. Today reports of 5,000 barrels a day leak and an oil slick thousands of square miles drifting towards the Mississippi river delta and Louisiana coast. This could turn out to be the biggest environmental disaster in US history. The message to places which are considering development of natural resources is clear: be careful!
