Bosco the bear died last year, but you can help the remaining animals at Pymatuning Deer Park,

The story of Bosco is sad.
Bosco and his female companion suffered for years in a cramped concrete pit.
In 2015, PETA first witnessed the female bear struggling to walk and alerted the U.S. Department of Agriculture (USDA) to her condition.
The agency inspected and cited Pymatuning for allowing her to suffer in pain without notifying a veterinarian and for confining the bears in a concrete pit where they were deprived of the opportunity to engage in normal behavior such as swimming, climbing, and digging.
Despite this, Pymatuning continued to keep both bears in the archaic concrete pit, even after Bosco started showing signs of arthritis.
Both bears are now dead.

PETA repeatedly offered to arrange for Bosco's transfer to an accredited sanctuary, but the owner refused to do what was right.

You can help the remaining animals.
Urge Pymatuning to close it's doors permanently and send the animals to reputable facilities.
