Regarding zoos, whether the Zetas have assembled zoos of terrestrial animals and plants on our own or other worlds. We have not sought to do this, nor would there be any purpose to such an activity. We came in contact with other worlds after we were granted the right to travel to these worlds. Since we have means to protect ourselves, we can insert ourselves into the natural habitat, as you say. Any zoologist will tell you that this is preferable, from a study point of view. In addition, it is not humane to imprison life, sentient and intelligent or otherwise. This has never come up for discussion, and none of our number has ever proposed this.
