Visitors to London Zoo last autumn stood enthralled, watching the family dynamics of the critically endangered Sumatran tiger playing out before them. The two newborn cubs, instinctively mischievous, repeatedly pounced and climbed up their 280-pound father, claws unsheathed. Crowds admired this tiger, built for predatory power, turning his obvious annoyance into gentle reprimands. The scene is reminiscent of Aslan the lion, whom C. S. Lewis used to capture some of the attributes of God—tender but also powerful and “not a tame lion.”
Today, these majestic cats are the focus of World Wildlife Day, along with the other big cats that are under threat on our watch—no, because of our watch. Habitat loss, conflict with people, and poaching are just some of the reasons for their drastic declines. There has been a 95 percent drop in tiger numbers over the last hundred years and a 40 percent drop in African lions over just 20 years.
