MANY ZOOS ARE KILLING HEALTHY ANIMALS THAT THEY HAVE BRED BECAUSE THEY ARE SURPLUS TO REQUIREMENTS. THIS CANNOT BE ALLOWED TO CONTINUE. THERE MUST BE A BETTER WAY CONTRACEPTION OF BREEDING ANIMALS ETC. ALL ANIMALS IN CAPTIVITY HAVE A RIGHT TO BE HEARD AND TO BE TREATED WITH RESPECT AND DIGNITY. STOP THE SLAUGHTER OF HEALTHY ANIMALS.
