We take a lot for granted in this country, and far too many people have absolutely no clue about the systemic relationships that affect our lives. Take nuclear reactors for example. For all the good they do, they also produce dangerous waste and have unique safety and security requirements. They are a target of NIMBYism, and understandably so. Meanwhile, most of us appreciate the benefits of nuclear medicine, which enables so many procedures that decades ago were inconceivable.
Ever think about where the isotopes come from that enable those procedures? Would it surprise you to find out that they come primarily from a Canadian reactor that is currently offline? We are dependent on foreign sources for those isotopes and are only now working on "growing" our own. The currently limited supply is having an impact in some quarters, hopefully not yours. But that could change with deleterious effects more widely felt.
Think about that the next time you assume we can simply "do" something to fix whatever the problem du jour is. We can shut down American nuclear reactors if we choose to. Can we really live with the consequences if we do?
