The San Diego Wild Animal Park, Indianapolis Zoo and others have created spacious, naturalistic elephant exhibits. What I personally cannot stand is Taronga Zoo in Australia having 5 elephants in half an acre, or Chester Zoo having 6 or so elephants in 2 acres, or the Oregon Zoo having 7 elephants in 1.5 acres. It's ridiculous that three well-known zoos have such tiny pachyderm paddocks.
I can't recall if I've ever mentioned on this website that all zoos should no longer have elephants in their collection. What I have definitely complained about, and I'm a voracious reader of animal-related literature, is that elephants have suffered greatly in zoos. It's that simple. The sheer catalogue of foot injuries of captive elephants is appalling, and yet there are still zoos that keep bulls in puny rooms that are demeaning and defy any logical educational purpose. If there are 85 North American zoos with elephants, I'll go on record by saying that 65 of those exhibits are inadequate and should be torn down/renovated/bulldozed/demolished.
I love zoos to death and just visited 30 this year, but there are problems big and small at every single one of them. Seeing a beautiful sumatran tiger exhibit at a particular zoo might be impressive, but then when the cats are locked into tiny rooms for 10 hours a day the effect soon wears off. Big cats, bears and elephants traditionally do terribly in zoos, and someone once mentioned on ZooBeat that out of dozens of North American polar bear habitats there is exactly one that is adequate for the bears. If the Detroit Zoo has the only truly decent polar bear exhibit out of 220 AZA zoos then there is surely a problem with showcasing that species in captivity. I am brutally realisitic when it comes to zoos, and having seen atrocious elephant exhibits at zoos such as Fort Worth, Memphis, etc it is disappointing to notice that the world-class elephant habitats around the world represent maybe 10% of the entire list of elephant enclosures. I'd guess that 90% of zoos worldwide with elephants have the animals in substandard paddocks, and I could list a huge number of zoos that still lock their elephants up at night in tiny cells. I'm not saying that elephants shouldn't be in zoos, but I'm just wishing that 90% of zoos either spend the money and improve the living conditions or get rid of the damn elephants. Bring on rhinos or some other mammal that adapts well to a captive lifestyle.
