Acidity on the half shell

This article explores the alarming effects of ocean acidification caused by CO2 emissions on marine ecosystems, particularly oysters. It explains the chemical processes involved, such as the formation of carbonic acid, and discusses the negative impacts on oyster larvae and hatcheries, notably the failure of the Whiskey Creek Hatchery in Oregon. The piece highlights the importance of maintaining a healthy ocean, the role of upwelling in nutrient distribution, and the ongoing efforts to monitor and address ocean acidity through various programs and research.
