It’s unlikely that some marine life that we depend on will be able to adapt to a rate of acidification that is over ten times as fast as during the PETM.

Microplastics Invade Arctic Ice

The rest were pieces of various other types of polymers — polyester, nylon, polypropylene, polystyrene, acrylic and polyethylene. Identifying the tiny pieces fell largely to Thompson, whose research has focused on marine debris, Obbard said.
