Zoos
	Zoos are places of entertainment for the masses where animals are kept behind fences and subjected to strange foods, medications, anesthetic drugs, constant contact with humans, breeding techniques, etc. & etc.; to live out a totally unnatural existence, not allowed to die once their natural existence has become impossible.        Perhaps it would be good thing to put the humans behind fences. But are not humans behind fences of their own making? But why should other animals have to be behind fences just because humans are?
