@lumpy is absolutely correct. Think of crested geckos, for example. They went “extinct” (by definition), and then were rediscovered in the 1990s. They would still be at risk in the wild if it weren’t for the pet trade. Now, it’s virtually impossible for them to go extinct again because of their huge success in the pet trade, if the wild population is at risk it would likely be possible to release captive geckos into the wild (this has been done with many reptile and animal species already). It is also how most reptile morphs are discovered and founded. There is a reported animal in the wild and it is caught and brought in captivity. I don’t think it’s cruel because often that animal has amazing patterns and it would not have lived very long in the wild and if it did it would harm the gene pool by constantly producing high-patterned animals that won’t live very long in the wild.
