This is Knut. Stuff reports he is an orphaned polar bear because his mother rejected him. So one of the zoo keepers has become his adoptive parent, bottle feeding him and washing him etc.
This is of course blasphemy to the animal rights extremists who say they think this will humanise Knut too much. They want the zoo to execute Knut instead. Yes, seriously.
Luckily Berliners are sensible people and support for the zoo is everywhere. In fact if the zoo did change its mind and try to kill Knut, they would probably be over-run by a rescue mob.
