Thanks to Karen Weintraub for this stark reminder, one of countless examples, of why so many places, and some big companies and many individuals are doing their best to get plastic out of daily routines:
Just a Few Pieces of Plastic Can Kill Sea Turtles
A new study shows that especially for young turtles, ingesting just a little more than a dozen pieces of plastic in the ocean can be lethal.

All over the world, sea turtles are swallowing bits of plastic floating in the ocean, mistaking them for tasty jellyfish, or just unable to avoid the debris that surrounds them.
Now, a new study out of Australia is trying to catalog the damage.
While some sea turtles have been found to have swallowed hundreds of bits of plastic, just 14 pieces significantly increases their risk of death, according to the study, published Thursday in Scientific Reports.
Young sea turtles are most vulnerable, the study found, because they drift with currents where the floating debris also accumulate, and because they are less choosy than adults about what they will eat.
Worldwide, more than half of all sea turtles from all seven species have eaten plastic debris, estimated Britta Denise Hardesty, the paper’s senior author and a principal research scientist with the Commonwealth Scientific and Industrial Research Organization in Tasmania. “It doesn’t matter where you are, you will find plastic,” she said.
