- Observing animals in conservation areas and zoos can encourage practical concern for their cousins in the wild
- Tourism can be vital for local economies
- As last resort zoos can keep populations of wild animals that may disappear in the wild (provided zoo’s have the expertise)
- Zoos cannot retain the genetic variability of a wild population
- Threatened species need to attract cash to justify their protection and existence
- There can be zoos without bars (but this is a weak argument since even with open spaces, a zoo is enclosed)
- Opportunity for scientific research
- Questionable when animals are simply kept for the entertainment of the public
- The assumption of species superiority
- Animals have consciousness, sentience, and intentionality
- Their “natural” behaviours have to be recognised and catered for
- The captive breeding of threatened species
- Intense viewing of creatures can interrupt feeding patterns and cause stress
- Captive animals can provide a genetic “lifeboat” for those in the wild
- Opportunities to adopt an animal
