Put those fears aside, because in the U.S., you're far more likely to be killed or injured by a deer bounding across the road.

Bambi and his kind cause more than 200 human 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 thrive 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 restoration could make a really big

difference.

University of Washington wildlife biologist Laura Peru.

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. Crunching the numbers, the researchers say that bringing the big cats back to the

eastern U.S. would mean 22% fewer collisions between cars and deer over three decades. Each

year would see five fewer human deaths,
