Marine mammals do breed in captivity, but the birth rate in captivity is not as successful as in the wild. Many people think that marine mammals should remain in captivity. Captivity shortens animal life spans, not increases them. Wild dolphins can live 40 years in the wild and orcas can live 90 years, but when held in captivity they rarely survive their teens. Twenty-three out of 25 orcas have died in captivity.
Some people think that holding animals in captivity helps with study and research.
But the truth is scientists prefer to learn about animals in their natural environment so they get firsthand knowledge. In conclusion, I think marine mammals should definitely not be held in captivity. In a world where much of nature and the wild has already been lost to us, it is up to us to let these beautiful marine mammals free. Read our Privacy Policy Statement .
