The Copenhagen Zoo provoked outrage for its killing of a healthy giraffe named Marius in February.
Now, it's back in the spotlight after euthanizing four lions. The zoo argues that it was a necessary move, to accommodate a new male lion. It explains that the new arrival would likely have attacked and killed two of the younger lions anyway.
To discuss the controversial practice of euthanasia by zoos, Max spoke to animal rights activist Mirja Holm Thansen. She said "Copenhagen Zoo is playing God. It's immoral and unethical to interfere with the circle of life by killing healthy animals."
Connect the World also asked Copenhagen Zoo whether they wanted to appear on the program, but they responded that they had nothing more to say on the matter.
