Sadly Bill, the whole pet trade is at a point where in some situations it has become or will become an ironic necessary evil. There are species who 30 or 20 years ago were introduced into the pet trade but now exist only in the hobby community. Their natural habitat either no longer exists or has been significantly compromised by human interference. Those who have never cared for animals tend to automatically point to the excessive over harvesting of wild caught creatures and while that may be considered a valid point it sometimes is not an isolated factor. Ie - Deforestation, due to growing agricultural needs, is a major component in the shifting of ecological stability. If someone didn't initially remove a certain species from a region that would be quickly processed for say farming developments, that said species may have simply been wiped off the map and yet another sad entry in the book of extinction. Topics like this sometimes lack a distinct black and white but are a murky gray.
