“People don’t come to zoos to see anything unhappy. They come to see animals playing. They come to see healthy animals. So that kind of developed for us into saying, ‘Oh, let’s not talk about the darker parts,’ ” said Mike McClure, general curator of The Maryland Zoo. “With the culture shift today, there’s a huge level of transparency. We now see there’s nobody perfect in the world. Zoos need to come out, too.”
