Harming the ocean impacts children in low- and middle-income countries

When discussing the socioeconomic effects of climate change, little attention has been given to the role of the ocean. This column presents new evidence of the effect of ocean acidification on early-childhood mortality in low- and middle-income countries. Small increases in exposure to water acidity while in utero have significant effects on neonatal mortality. A closer look at possible mechanisms highlight the role of the ocean for nutrition and how overfishing represents an additional threat.
