These disconnected into marginalized zoo and ecologically isolated islands despite seeming free and not having noticeable physical barriers like walls or bars around them in fact do act as such...large caged zoos where many species like jaguars, elephants, wolves, bears, bison, elk, caribou, lions, rhinos, hippos, leopards, cougars, wild horses, pronghorn, wildebeest, antelope, ... are no respecters of man's wilderness and park boundaries on a map. They will be lost because of man's ignorant ecological misguided tinkering with, at it's core, the human centric Abrahamic world view and mindset that presupposes man is apart from and above a larger ecological whole. It is yet another example of humanity's widespread failure to recognize a larger ecologically integrated interconnected whole. More humans = less biodiversity of other species! That's the tale humanity wishes to ignore and lie to itself about despite the political or economic system in which it occurs. Welcome to the present - a period of mass species endangerment and extinction on land, in the sea, and in the air with man's behavior as the cause that will increase as man increases.
Damn well right better step up efforts to colonize Mars. The next planet a disconnected humanity arrives at with their parasitic self species centered mindsets similar to an over populated rampaging hoard of locusts that devour everything in their path until they start turning on and devouring each other.
