The Earth is the gravitational vacuum cleaner in its orbit around the sun. The reason that we have such a large planet is due to the accumulation of debris as we travel around the sun. Each day as we orbit the sun, we sweep up enough dust to equal the weight of 100 elephants. Sometimes, the dust is large enough to glow brightly as it burns up in the atmosphere. Other bits are large enough to survive the high-speed trek through the atmosphere and land as tiny pebbles. Larger debris, or asteroids, will collide with Earth and create impact craters on the surface of the Earth, leaving a scar that withstands centuries of erosion to hint at just how vulnerable we are to climate-changing collisions from space.

What would be your response to the news that an asteroid, 1-km wide, will hit the Earth in three years?

Should this news go public?

Would you keep your job or seek employment?

Would you volunteer to be part of a select few to survive in a bunker until the skies cleared if it meant that most of humanity wouldn't survive the impact?
