In a Word: Plastics

The most famous career advice ever given to the baby-boom generation came in a single word in a 1967 movie: Plastics. It was supposed to be funny, but it turned out to be prescient. Since the premiere of The Graduate, shares of plastics giant DuPont(DD Quote) are up almost 2,400%, double the return of the broad market.

Thirty-nine years later, strangely enough, you could easily give the same advice, as the makers of everything from MP3 players and golf shirts to cars, corn, computers and container ships are turning to plastics and advanced chemicals to cut weight, extend life and improve durability. The latest blow for the primacy of polymers came last week when federal regulators approved the use of silicone in breast implants after a two-decade ban. It's goodbye wonders of nature, hello miracles of science. Synthetics or bust.

The beauty of plastic is more than skin deep, but it's so ubiquitous that we take it for granted. Consider that when marveling at the iPod, you're apt to praise its rich sound and sharp video. But really, how about that lovely case and vivid LCD screen? The device's smooth finish, light weight, bright color and remarkable strength would not be possible without significant advancements in the development of low-cost materials.

Fantastic Plastic

It's fashionable in some circles to complain about chemicals in food, water and hair products, but just try to live without them. Engineers in labs have developed new pesticides and seeds that increase crop yields without poisoning the food chain; chewing gum that lasts longer and whitens teeth; soft polyester shirts that wick sweat away from your skin at the gym; bombproof glass; and spongy but indestructible turf for kids' soccer games. The Stone Age was cool and everything for Neanderthals, but count me as happy to live in the Plastic Age.
