Are you afraid of sharks? What about snakes or spiders? Put those fears aside: because in the U.S. you're far more likely to be killed or injured by a deer skipping across the road.
Deer cause more than 200 humans deaths each year, plus some 29, 000 injuries, all because of 1.2 million collisions between vehicles and deer. Most incidents occur in the eastern U.S., where deer prosper without natural predators like wolves and mountain lions.
"That's the region in the U.S. where deer-vehicle collisions are such a problem, and where it seems like an effective large carnivore reintroduction could make a really big difference." says wildlife biologist Laura Prugh from University of Washington. She thinks it would help to reintroduce predators like mountain lions, also known as cougars, pumas or panthers, to parts of their historic range from which they've been driven out.
The researchers say that bringing the predators back to the eastern U.S. would mean 22 percent fewer collisions between cars and deer over three decades. Each year would see five fewer human deaths, 680 fewer injuries and a savings of some 550 million. Sophie L. Gilbert thinks there are great socioeconomic benefits of large predator restoration through reduced wildlife-vehicle collisions and she says, says, "Cougars have shown that they can coexist in short distance with people, with very few conflicts, in a lot of areas out west."
Still, some folks might be understandably nervous about this kind of plan. After all, reintroducing predators doesn't come without risks to pets and to livestock, and very occasionally to people.
"Our fear of large predators is so natural and intense that I don't think it's possible to just completely clear it with statistics… What I hope is that knowing that there actually can be some measurable benefits might make people a little more supportive and maybe balance that fear a little bit." says Laura.
Indeed, the statistics show that cougars would prevent five times as many human deaths from deer-related accidents as they would cause by attacks. But it'll be a tough sell: the press will cover cougar attacks, but a statistically prevented death does not make the news. Nevertheless, "If people in the west can put up with having mountain lions around, I would hope that New Yorkers would be up for the challenge as well."
