California Sea Lion Plays with Mask

A California sea lion swims towards a face mask at the Breakwater dive site in Monterey, California, USA, on 19 November. California sea lions (Zalophus californianus) are playful animals, native to western North America. With COVID-19 lockdowns in place across California, outdoor and natural beauty spots with plenty of wildlife became a popular focus for local travel. In many countries the wearing of face masks outdoors was obligatory. Similar destinations around the world became littered with abandoned masks. The BBC reported an estimated 129 billion disposable face masks and 65 billion throwaway gloves being used each month through the pandemic. Such personal protective equipment (PPE) can be mistaken for food by birds, fish, marine mammals, and other animals. PPE also contains plastic, and so contributes to the eight million tons of plastic that end up in the oceans every year.
