You’re voting for a zoo that has facilitated the loss of many pangolins through irresponsible importation and cooperation with a rather shady (to say the least) animal dealer in order to do so.
This helpful post by DDCorvus explains the situation:
Several US zoos receive pangolins
Brookfield’s current pangolins are from two 2016 imports. They received several individuals, but about 1/4 imported individuals died. They had participated in earlier imports as well: all of which had 100% mortality rate.
Brookfield’s animals are “rescued” from Togo, ie they unfortunately wandered onto a farm and were captured. The animals were taken from the wild simply for moving about as they normally do. In turn, a horribly high percentage died, and there are now multiple farms in Togo which equate the capture of pangolins with money. In addition, this all filtered through Justin Miller, head of Pangolin Conservation. While their intents are honorable, his methods are disappointing: he has written off all Asian pangolins as too late to save, and rather than cooperating with zoos that already have established pangolin diets, he made his own. If one were to search around on the internet, has background isn’t exactly one of someone who is conscious of animal needs. And after he sees this, he’ll probably write me another email threatening me like he did the last time I posted something about him on this site.
