But the truth is in the middle. Progress is made in the the coronavirus currently ravaging china is also taking a heavy toll on one of that countrys most endangered animals, the pangolin. Chinese scientists floated the idea that these scaly mammals kicked off the epidemic. Tom hanson has more. Reporter at the Brookfield Zoo just outside chicago, scientists are working around the clock to save some of the most vulnerable creatures on the planet. Meet biggie, one of 11 whitebellied three pangolins living here. The pangolin has spent most of its existence in obscurity. But after a group of chinese scientists recently labeled them as the potential transmitter of the novel coronavirus, now its at the center of a pr nightmare. What they found was a coronavirus that was very, very similar to what theyre seeing now coming out of wuhan. And so there is that possibility. Its still that Research Still needs to be vetted or have peer review before anyone can say with any certainty at all that thats where it comes from. Reporter scientists across the globe, including bill ziegler at brookfield have questioned the findings of the research. Still, the potential backlash against these endangered animals is worrisome. My concern is if we dont word it right and people become afraid of pangolins, they may go out and if they find a pangolin in the wild in which case there is no real issue there, its not a danger to you as far as transferring a disease, they would kill it anyway, because theyre afraid of it. Reporter even though its illegal worldwide, these oddlooking animals are heavily poached for their prized meat and their scales which are believed to have medicinal value, earning them a title as the most trafficked mammals on the planet, and causing some populations around the globe to drop to critical levels, something zieglers team is trying to change. The Brookfield Zoo is one of seven groups in the u. S. Working to breed pangolins, and theyre one of the most successful, with nine births over the past four years. But heres what scientists are up against. Its estimated up to half a million of these animals are poached every year. Its a daunting challege and a critical time, but ziegler and the consortium of scientists Hope Education will save these gentle animals from disappearing. Youre going to see an increase in the breeding and the successful birth of these animals as we build the Science Behind the reproductive physiology of these animals. And thats our goal, not only to help provide the science to erve the species, but we want to establish a sustainable population here in north me. Reporter tom hanson, brookfield, illinois.
