In 2002, scientists discovered a large "dead zone" off the coast of Oregon - a marine area that has virtually no oxygen and thus can't support life. Dead zones are incurring with increasing frequency all over the world. Scientists believe that changes in weather -- sound familiar? -- are contributing to the ever increasing size of the Oregon dead zone. This summer's dead zone is one of the worst. Thousands of dead Dungeness crab, sea stars and other marine life carpet the ocean floor. Check out this video that made Al Pazar, chairman of the Oregon Dungeness Crab Commission and a crab fisherman himself, "weak in the knees."
