Plastics

摘要

When the titanic plunged to the ocean floor in 1912, it became an underwater time capsule, a snapshot of life in the early 20th century. Salvagers who recovered the riches aboard the wreck 75 years kter were struck by the absence of one material: plastic. That's impossible to imagine today. Since 1976 plastic has been the most widely used material in the United States. "In the five decades since World War II, plastic has crept unceasingly, and often invisibly, into our homes, cars, offices, even our bodies," writes Stephen Fenichell in his book "Plastic: The Making of a Synthetic Century."
