Response Questions Week 4 IR


>> RESPONSE QUESTIONS 3     

1-  Sarah Long, a coordinator of breeding at Lincoln Park Zoo, argues in Date Night at the Zoo that “Noah got it all wrong.” What does she mean by this? What strategy are zoos taking to “get it right”? What are the pros and cons of this strategy on the part of zoos? Discuss them in the context of animals like cheetahs, black-and-white ruffed lemurs, and polar bears. Reference SSPs in your response.

In order to avoid in breeding, a large population of animals must be held and bred together in a manner designed to maintain genetic diversity. Two of each animal, Noah’s Arch, just won’t cut it for repopulating a species. If zoo’s want a chance to keep a healthy population of animals, one which could possibly rejuvenate a depleted population in the wild, then they need to plan who breeds with who very carefully.

Zoos are doing a lot to meet this goal. In 2000 the association opened the Population Management Control Center to analyze to genetics of zoo animals and determine the best breeding plan for genetic diversity. Many zoo’s are giving their animals contraceptives, to avoid unwanted pregnancies between animals that are too closely related. Zoo’s outside America even euthanize animals in order to avoid inbred offspring reproducing later down the road.

Because such a large population of one species is necessary, then zoo’s are needing to cut down on the amount of species they hold. Some species, sadly, are being phased out of zoos in favor of species that can be maintained in captivity and have a chance of returning to their natural habitat at a later date. Because of this, some species will probably go extinct, because their population does not supply enough genetic diversity, or their habitat is too far gone to return to.

2-  If conservation is a key goal, then what is the tension between funding resources and the how zoos go about conservation? What are the alternatives – what do some other people should be done with such funds if conservation is the primary motive?

Some people think that the funds need to go to animals that have a chance of being transplanted back into the wild if the wild population is driven to extremely low levels. Therefore some animals, like the polar bear, no longer has a place in the zoo. With melting ice caps polar bears are not likely to be able to survive if populations from zoos are released into the wild at a future date. Therefore, if conservation is the only motive, resources would be best spent breeding other animals, and polar bears should be phased out of zoos.

This is controversial, because animals like polar bears are the most popular residents at zoos. People come to see them. They achieve other zoo goals, such as inspiring people to care for the fate of animals, and they bring in zoo revenue. Zoo directors are likely to spend money on things like new exhibits for popular charismatic animals, such as polar bears, while conservationists urge zoos to spend their money on species who have a higher chance of benefiting from zoo breeding.

3-  Many zoos argue that the first hand experience with animals at zoos are crucial for helping people to form bonds, and thus develop a care and sense of conservation ethic, for endangered animals. The Wild Thing piece on the National Zoo especially makes this argument. What is your view?

I think it is completely true. Seeing an animal in real life can instill a sense of wonder that nothing else will do. It is argued that there is no way to support that zoos inspire people to spend money on conservation. I argue that there is no data because it cannot be measured. Not everyone who goes to a zoo will immediately be able to spend huge sums of money on animals, but it could affect society and individuals positively in less noticeable ways. Someone could be inspired to be a conservationist, a scientist, an artist. You never know what a child, in love with a polar bear at a zoo, will do as an adult. How has this experience changed him? For the better I’m sure, even if he doesn’t immediately start rallying to turn the entirety of Alaska into conservation land.

4-          What is a difference between American and European zoos in terms of their philosophy of captive animals breeding if room does not exist for the adult population to grow given the size of the zoo habitats? Which approach makes more sense to you and why? How does the European approach relate to the logic of conservation and the issues of genetic diversity that underlie them?

European zoos tend to euthanize their animals much more often than American Zoos. American zoos give their animal’s contraceptives in order to avoid unwanted breeding when males an females are housed in the same exhibits.  European zoos don’t believe in this, saying that keeping animals from reproducing is further alienating them from their nature. Instead, these zoos opt to allow animals to reproduce, rear their young to the age where they would naturally leave their parents, and then euthanize and offspring that is too inbred to contribute to a genetically diverse population in captivity. This view is actually more conservationist, because it allows for funds to only be spent on animals that can be used to replenish depleted groups in the wild. However, it also involves killing innocent baby animals, which tends to go against the gut reaction of most people trying to conserve animals.
