Meteorite colliding with Earth. Illustration of an enormous meteorite colliding explosively with the Earth. Several other meteorites are shown flying through Space. Collisions like this are a statis- tical certainty in the Earth's future, and would be catastrophic for mankind. The "nuclear winter" that could follow the impact would profoundly dis- turb global ecology, leading to mass extinction. Collision of a comet or meteorite with Earth is thought by some scientists to account for the mass extinction of dinosaurs 65 million years ago. Fossil evidence, however, suggests the dinosaurs disappeared over millions of years.
