Parents need to be diligent and read labels carefully because not all store managers think to carry the healthiest foods for our kids. So we go shopping around from store to store looking for mercury-safe tuna, for instance.
Learning that bluefin tuna caught off California contain traces of radioactivity is disturbing regardless of health risks to diners. But the fact is, when it comes to tuna, we have more serious problems to worry about, like mercury and overfishing.
We know the whole world is connected, but we didn't quite think about how some of the connectors travel awfully far awfully fast. Long before tsunami debris arrives on shore, some California sport fishermen are catching radiation packages.
