This small shellfish has a superpower. Not only can oysters make pearls out of grains of sand… and taste incredible on the half shell… they can also completely transform their environment.

One oyster can filter up to 50 gallons of water in a single day, leaving it cleaner and healthier. These amazing shellfish are like the natural cleaning crew of the ocean.

But ocean acidification and other climate-related changes are threatening oyster populations, which could be problematic for their entire ocean ecosystem.

Find out exactly why ocean acidification is so damaging to oysters in this ReWild.
