Three elephants named Mara, Kuki and Pupi have officially filed a lawsuit against the the Buenos Aires Zoo, where they currently reside, claiming that their quality of life there amounts to animal cruelty. Well, to put it more accurately, their lawyer, Andres Gil Rodriguez, has been allowed to state these claims on behalf of his pachyderm clients by the court, but the elephants really are suing the zoo for animal cruelty. No, really.
The argument is that the elephants could have a much better life at an elephant sanctuary had they not been held captive by the zoo for profit. And ever since a 2014 ruling which declared that an orangutan has the same rights as humans, they actually might win.
