That's right. All those goods you're paying to get for cheap from China. Those winter blueberries from Argentina. South African wines. Well, they come with a hidden cost. Pollution from marine shipping causes approximately 60,000 premature cardiopulmonary and lung cancer deaths around the world each year, according to a study from the Rochester Institute of Technology. The researchers correlated the global distribution of particulate matter—black carbon, sulfur, nitrogen and organic particles—released from ships' smoke stacks with heart disease and lung cancer mortalities in adults. Worse still, the predicted growth in shipping could increase annual mortalities by 40 percent by 2012.
