Pacific Ocean

The amount of plastic debris in the part of the Pacific Ocean known as the "Great Pacific Garbage Patch" has grown 100-fold in the past 40 years.

In a paper published today by the journal Biology Letters, scientists from Scripps Institution of Oceanography report that most of that plastic has degraded into pieces no bigger than a fingernail. But that wasn't the major finding the scientists are reporting.

The scientists have found that all those pieces of plastic have provided ample opportunity for insects called "sea skaters" to breed.
