One can visit an iguanario in the same city where one can eat iguana???
Like reforestation projects near carpentry heavy villages: as long as you keep producing what you're going to use (or eat) its better than if you continue to consume but not cultivate!

When you put it like that, it makes perfect sense. They don't seem to be an endangered species, judging from what I saw in the Yucatan a few years back. I recently learned that we have iguanas in the California despert where I live, but
they are much smaller and rarer, which makes sense as we get 2-3 inches of rain per year.
