"According to astronomers, a NEO [Near Earth Object] of around 50 m in diameter collides with the Earth every 100 to 300 years and a NEO with a diameter of 1 km occurs every few hundred thousand years. Very large collisions, that could threaten the existence of all large land species, occur once every hundred million years. To date, astronomers have identified 600 NEOs bigger than 1 km but believe that there are possibly half as many again still waiting to be tracked."

DonDiego doesn't know if they can comprehend the idea of mountain-sized chunks of rock floating through outer space.
But they do know what a volcano is.
"The [Yellowstone Caldera] formed during the last of three supereruptions over the past 2.1 million years. First came the Huckleberry Ridge eruption 2.1 million years ago, which created the Island Park Caldera and the Huckleberry Ridge Tuff. Next came the Mesa Falls eruption 1.3 million years ago, which created the Henry's Fork Caldera and the Mesa Falls Tuff. Finally came the Lava Creek eruption 640,000 years ago, which created the Yellowstone Caldera and the Lava Creek Tuff."

So, DonDiego could suggest to them that a catastrophic eruption of Giant Volcano in Yellowstone National Park, where Yogi Bear hangs out, could bury everyone in the United States under several feet of deadly ash.
