I’m not proposing this as an actual solution, it’s just a dumb idea. But if we dug a huge, wide hole at the bottom of the ocean, or maybe widened the Mariana Trench or something, could that extra space make the sea levels drop enough to keep the land from flooding?
Next time I go to the beach I’m bringing a shovel, and will dig a hole just past where my feet get wet.
I’m doing my part.
