If raining chunks of Moon didn't slam into Earth, there would still be long-term consquences for our planet if the Moon no longer existed. The Moon helps stabilize Earth's tilt on its axis so that it doesn't wobble out of control. Without it, Earth might wobble much more as it spins, causing seasons and climates to change.<br /><br />Who knows, it's possible that the hot and dry lands of the Sahara Desert would become snow-covered and icy, similar to the Arctic. Just one possibility of how it could change.<br /><br />So, if raining chunks of rock didn't cause a massive extinction, the absence of the Moon very well could.<br /><br />Many major extinctions have already happened in Earth's past. The KT boundry (the extinction of the dinosaurs) isn't even believed to be the largest by many scientists. <br /><br />Another one is coming, it's just a matter of when. A thousand years from now, a million years from now, a hundred million years from now.
