Stephen, don't get me wrong, I agree with you that both are important, and that overcollection of reptiles and amphibians needs to stop, period, and overcollection for food, profit, or otherwise, is just raping the land resources and I do not condone that behaviour. That is why it is best not to buy wild caught animals and support captive breeders, if there is no money in overcollecting, most of those people don't do it just for fun they do it for the money.
However taking in a few animals to captive breed and try to boost a local population, might be the only hope to maintain it? if its' habitat is being destroyed and it is a very small localized population? Even professional and governmental biologists do this.
The thing is, we can easily minimize the biggest treat. We can make a collective and conscious effort as an intelligent species to stop overpopulating the planet, however this is a heated topic that most would rather ignore . But even if we can't seem to accomplish that, we can also make an effort to stop detroying ecosystems by how, where, and when we devolope and how we dispose of our waste, and decrease our waste. If you have ever taken a microbiology class you are probably familiar with events that occur within a petri dish. The planet isn't infinate, it's just a great big petri dish and overpopulation of our species will cause the same end result.
The data charts really get the point accross the issues that we face as reptile and amphibian lovers, because most people really don't care if all reptiles and amphibians, especially snakes would all just simply disappear unfortunately. Thanks for sharing.
