It was wrong to capture wild animals and confine them in captivity for people to go and gawk at them. And that's basically how zoos got started. But once you do that, and once you have animals that have been bred in captivity, you're really stuck with them in some sense. You can't return them to the wild. Peter Singer
Through PETA, we rescue animals in roadside zoos and circuses. They are some of the most abused animals in the country. Sam Simon
When I was 7 and went to the zoo with my second-grade class, I saw chimpanzee eyes for the first time - the eyes of an unhappy animal, all alone, locked in a bare, concrete-floored, iron-barred cage in one of the nastier, old-fashioned zoos. I remember looking at the chimp, then looking away. Octavia E. Butler
I am personally not against keeping animals at zoos, as they serve a huge educational purpose, but treating them well and with respect seems the least we could do, and with 'we' I mean not just zoo staff, but most certainly also the public. Frans de Waal
Zoos are becoming facsimiles - or perhaps caricatures - of how animals once were in their natural habitat. If the right policies toward nature were pursued, we would need no zoos at all. Michael J. Fox
