Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Harvard T.H. Chan School of Public Health found that overfishing has caused some fish to switch their prey to species with higher mercury levels. They also found that rising ocean temperatures have led to fish becoming more active and needing more food—and thus ingesting more mercury.
Mercury has been linked with impaired brain development and cognitive abilities and is especially dangerous for fetuses.
Climate change “is not just about what the weather is like in 10 years,” said Amina Schartup, who led the study while a researcher at SEAS and Harvard Chan School, in an August 7, 2019 article in The Atlantic. “It’s also about what’s on your plate in the next five.”
