It’s not enough that we need to worry about climate change making the Earth inhospitable to human life. Apparently, now, scientists are starting to worry about the moon shrinking.

The moon’s shrinking has been measurable, but small. It has contracted about 150 feet in diameter over the last few hundred million years.

It’s impressive that we could know that, but it doesn’t seem like very much. What’s the problem?

There’s no reason Earthlings would need to be concerned with a shrinking moon — unless we move there.

Ah. OK, I guess astronauts should pay attention to this. As for me, I’m going to go back to ignoring it forever, so I can focus my energy on being terrified about existential threats on the celestial body where I currently reside.
