Another great talk from the Long Now Foundation's series of seminars on longterm thinking:
Susan Freinkel, a journalist, presents the story of plastic. Fascinating, informative, and ultimately disturbing, Freinkel tells how quickly this material has conquered the earth. When Titanic sunk, no part of it was plastic. Today, most of us would be very seriously challenged to get by even a few minutes without using something made of plastic. It's everywhere, and unfortunately it ends up accumulating in nature, in oceans and landfills, where it breaks down only very slowly.
If you have an hour or so for listening, this podcast will fill you in on the state of plastic.
