Sometimes it's easy to think that banning a harmful product, or cracking down on its disposal, can simply erase any future problems.
But a new study from Drexel University indicates that that might not be the case. Older readers may remember the infamous pesticide DDT, which was banned in 1972, ten years after the publication of Rachel Carson’s seminal book Silent Spring, which detailed the many ways in which DDT was ravaging the environment. (The pesticide might be most infamous for very nearly pushing the bald eagle to extinction.)
