By transforming ocean food webs, warmer temperatures can change the amount of minerals and fats that fish get through their diet, and potentially affect their metabolism and their ability to excrete toxic substances.

Though the research is still at an early stage, studies suggest some potentially worrying trends, including a widespread decline in omega-3 fats and higher toxin levels in certain fish species and other kinds of seafood. If such trends hold up with further research, this could mean major effects for human health.
