A record-breaking animal rescue operation ended Thursday when 25 Bolivian circus lions touched down at Denver airport in route to their new life within an 80-acre sanctuary.
The humanitarian airlift, called Operation Lion Ark, began last year when the group Animal Defenders International (ADI) won their campaign to effectively shut down the animal circus industry in Bolivia.
A 2005 ADI undercover investigation exposed horrific abuse in circuses across South America. The question was, where could the lions go after their rescue.
