But you have to realize that if NO ONE took any snakes from the wild. Which is what you want... There wouldn't be any snakes in captivity to breed. And there are still many species that are not available captive bred. So don't make sweeping decisions like that until you fully consider the consiquences.
Yes, thats defenitly very true. But...People are still catching gravid females of species that are readily available. There's just no "need" to do so.
Or at least, thats how I see it.
