Our moon is on the move. Each year, it drifts an estimated 1.5 inches further away from Earth. And in the process, Earth’s rotation is actually slowing down. What if one night, the moon simply disappeared? Would we miss it?
A full moon is on average 14,000 times brighter than the next brightest night-sky object, Venus. So without it, every night would be as dark as a new moon. And star gazing would be spectacular.
But by the next morning, you’d begin to realize just how important the moon is for life on Earth. To start, between the sun, Earth’s rotation, and the moon, the moon has the largest influence on Earth’s tides.
Without it, high and low tides would shrink by an estimated 75%. This would jeopardize the lives of many types of crabs, mussels, and sea snails that live in tidal zones and disrupt the diets of larger animals who rely on them for food, threatening entire coastal ecosystems in the process. Within a few decades, we would start to see mass population declines
