With global warming beginning to devastate human and animal life around the world, should we really be slowing or stopping solar development to save a single type of reptile? Moyle was ready with an answer: Tortoises are a keystone species. If they’re doing well, it’s a good sign of a healthy ecosystem in which other desert creatures — such as burrowing owls, kit foxes and American badgers — are positioned to thrive, too. And as the COVID-19 pandemic has demonstrated, human survival is inextricably linked with a healthy natural world. “We take one thing out, we don’t know what sort of disastrous effect it’s going to have on everything else,” Moyle said.
