The fate of "cuddly Knut" has gripped the German capital since his birth in December. Rejected by his mother Tosca, the cub was adopted by a zookeeper who moved into the animal's enclosure to care for him round the clock.
Some animal rights campaigners think this will humanize the bear too much and want the zoo to stop saving young animals.
"Hand-rearing a polar bear is not appropriate and is a serious violation of animal rights," Bild newspaper quoted animal rights campaigner Frank Albrecht as saying.
"In fact, the cub should have been killed," he added."
I don't understand animal rights' activists that actually think death is solution for the safekeeping the rights of an animal...Like life is below law. That is called orthodoxy. Too narrow and to stupid logic. In my opinion orthodoxy is just for the weak of thought.
