There has been a report revealing that wildlife has been devastated since 1970. Poaching and habitat construction have caused numbers of certain species to fall precipitously.
Animal rights activists have been pushing the notion that zoos are animal prisons. They seem to want all animals released into the wild. Some apply this not only to animals de ferae naturae. Some apply this to pets as well.
The solution to save animals from extinction is to completely reverse our approach. We must allow all sorts of animals to be kept as pets. This includes even beasts that cannot be domesticated. If a Chinese billionaire wants to keep African elephants on his estate he should be allowed to do so. This might be the only way to save these animals from being wiped out.
If tigers were kept in captivity and bred even through artificial insemination that would keep the species going. We could make the sale of tiger bone legal. It would mean the bottom would fall out of the market. There would be much more supply.
Captive breeding programmes saved oryxes and ibixes.
