the zoo contains different animals, all caged. politicans decided to finally free them and hand them back the lives they want to live. 
therefore altogether -politicians, researchers, the animals and philosophers- keep researching, making changes and finding ways.

recently india declared animals to have the same rights than humans. TO ME THIS IS A HUGE REASON TO CELEBRATE AND IN MY EYES IT CONCLUDES NEW LAWS WHICH MAKE THE KILLING OF OUR INNOCENT FELLOW BEINGs ILLEGAL.
