Great letter, Phyllis! I learned recently that the family of Jon Huntsman, a minor presidential candidate (R-Utah), sponsors a foundation to cure cancer. Meanwhile, Huntsman's father made billions by inventing and producing the styrofoam plastic "clamshell" boxes formerly used to package McDonalds hamburgers and Filet-o'-fish sandwiches. Environmentalist pressure eventually forced McDonalds to abandon styrofoam. We'll never know how many cancers were caused by the manufacture and use of all that styrofoam. Not to mention how much of it is now floating in the ocean, and how much ozone-depleting, global-warming gases were emitted.
