Widely varying estimates of severity of oil leak in Gulf raise many questions
After BP released underwater video footage of the oil gushing into the Gulf of Mexico, conflicting estimates of the amount of oil leaking raise many questions.
What is the rate of flow? How much oil is already in the water? Is there any way to make an accurate assessment? When will it hit shore? What will be the economic and environmental impact? Does anyone really know the answers, and if so, who is telling the truth?
