The Natural Resources Defense Council Web site has a page devoted to the Gulf of Mexico oil spill, with their own on-the-ground coverage together with many excellent articles that describe the disaster and its implications and meaning, including a thoughtful piece by Lisa Margonelli, which appeared in the New York Times -- "Driving Oil Dependence Down."
Other articles include "Which Would You Choose: Offshore Wind or Oil?"; "The Impact of the Oil Spill on Community"; and "From Canada to the Gulf Coast: The Unhealthy Tale of Petroleum," and many others. NRDC has called for a time out on new offshore drilling activities.
Take action by going to the Sierra Club's Web action page site, "Say NO to more dirty, dangerous offshore drilling."
