Oil Well Destroying Environment Even Before The Spill

Since the 1930s, oil and natural gas companies dug about 10,000 miles of canals, straight as Arizona highways, through the oak and cypress forests, black mangroves, bird rushes and golden marshes. If lined up in a row, the canals would stretch nearly halfway around the world.

They funneled salt water into the marshes, killing trees and grass and hastening erosion. Some scientists say drilling caused half of Louisiana's land loss, or about 1,000 square miles.
