Does it really though? That area is pretty saturated with AZA zoos, not to mention the decent number of non-AZA facilities in the area. Binder Park (Battle Creek) is 35 min away, John Ball (Grand Rapids) is under an hour, Potter Park (Lansing) is around an hour and 15 mins, Potwatomi (South Bend, IN) is around 1.5 hours, and Fort Wayne is about 2 hours. Those are just the zoos in the typical 2 hour radius the average zoo visitor comes from. If we extend that just slightly you then get two major zoos in Detroit at about 2 hours and 15 min away and Toledo at about 2.5 hours. (All times estimated by using Google Maps and "Kalamazoo, MI" as the starting point.) I'm not from the area, so perhaps locals do feel like there is not a zoo close enough, but I doubt it. I have a feeling a zoo in Kalamazoo, even a small one, would have a very hard time getting any traction and funding to even start it. The only argument I see for "it needs a zoo" is it is a somewhat bigger city in Michigan that doesn't have one, but that ignores the fact there are a number of places that are pretty easily accessible.
