I remember watching the film “The Graduate” years ago. The movie begins with a young Dustin Hoffman as a college graduate. There’s a party scene at the family’s swimming pool. What field should this young man pursue in the mid-1960s? Someone whispers in his ear, “Plastics!” Today it would probably be software, but the business acumen was on the mark back then.

Haveyou ever thought about the long-term effects ofplastic building materials on the environment?
