Let the Zoo's Elephants Go
The Smithsonian Institution is a national treasure, but when it comes to elephants, its National Zoo is a national embarrassment.
In 2000 the zoo euthanized Nancy, an African elephant that was suffering from foot problems so painful that standing had become difficult for her. Five years later the zoo has announced that Toni, an Asian elephant, is suffering from arthritis so severe that she, too, may be euthanized [Metro, Sept. 6].
The elephants' debilitating ailments are probably a result of the inadequate conditions in which they have been held. The same story is repeated in zoos across the country.
When I began my zoo career 35 years ago, much less was known about elephants than is known today. We now understand that keeping elephants in tiny enclosures with unnatural surfaces destroys their legs and feet. We have learned that to breed naturally and rear their young, elephants must live in herds that meet their social requirements. And we have come to realize that controlling elephants through domination and the use of ankuses (sharply pointed devices used to inflict pain) can no longer be justified.
Zoos must change the concept of how elephants are kept in captivity, starting with how much space we allot them. Wild elephants may walk 30 miles a day. A typical home range of a wild elephant is 1,000 square miles. At the National Zoo, Toni has access to a yard of less than an acre. Zoo industry standards allow the keeping of elephants in as little as 2,200 square feet, or about 5 percent of an acre.
Some zoos have begun to reevaluate their ability to house elephants. After the death of two elephants in 2004, the San Francisco Zoo sent its surviving elephants to a sanctuary in California. This year the Detroit Zoo closed its elephant exhibit on ethical grounds, and its two surviving elephants now thrive at the California sanctuary as well.
But attitudes at other zoos remain entrenched. To justify their outdated exhibits, some zoos have redefined elephant longevity and natural behavior. For example, National Zoo officials blame Toni's arthritis on old age. But elephants in the wild reproduce into their fifties, and female elephants live long after their reproductive cycles cease. Had she not been captured in Thailand at the age of 7 months, Toni, at age 39, could have had decades more of life as a mother and a grandmother. Instead, she faces an early death before her 40th birthday, is painfully thin and is crippled by arthritis.
The National Zoo's other elephants face the same bleak future if changes are not made. A preserve of at least 2 square miles -- 1,280 acres, or almost eight times the size of the National Zoo -- would be necessary to meet an elephant's physical and social needs. Since this is not feasible, the zoo should send its pachyderms to a sanctuary. One such facility, the Elephant Sanctuary in Tennessee, offers 2,700 acres of natural habitat over which elephants can roam and heal from the damage caused by zoo life. The sanctuary's soft soil, varied terrain, freedom of choice and freedom of movement have restored life to elephants that were suffering foot and joint diseases after decades in zoos and circuses.
The National Zoo has the opportunity to overcome its troubled animal-care history by joining progressive zoos in reevaluating its elephant program. The zoo should do right by its elephants, and the public should demand nothing less.
