Time and time again when we are faced with human-caused disasters, like the oil spill off the coast of California, a tragic confirmation of what we know far too well – offshore drilling is dirty and dangerous, and when they drill, they spill."

Kourtney Kardashian shared several swimsuit photos from her Cabo vacation with her fiance, Travis Barker.
