Landhi Korangi is a privately operated zoo, the people in charge run it as a money making business. And because it is not answerable to any wildlife dept. there hasn't been any work done to improve the general situation of the zoo and it doesn't seem likely in the near future. I'm pretty sure they've had animals deaths due to consumption of plastic via all the trash present in the cages, but again since it is a private zoo no reports whatsoever surface about it. I sincerely hope they shut this place down asap.
