Take One and Pass It Down: Antacids for the Ocean

If you’ve ever found yourself reaching for an antacid after an indulgent round of feasting, you’re in good company—the ocean is taking antacids, too!

Our stomachs produce acid to digest all the food we eat. Sometimes, foods can cause acid to leak into the esophagus, creating the sensation we associate with heartburn. Antacids are chemically basic compounds, and taking one helps to neutralize stomach acid, reducing its ability to irritate our esophagus. Scientists looking to reduce the acidity of the ocean—and in tandem counteract climate change—are applying the same strategy!
