No, i rathet not. Because i just don't understand the concept and benefit of held captive to lions, camels, monkeys etc. They don't under danger of extinction. Yes, i love them to save the species nearly extinct because they have to. We made those animals to extinct afterall! As regards to research part, i don't believe researchers need to captive animal for this. No. They may travel their habitat and i bet get even more accurate data about them in there.
