Climate change is pushing fish toward the planet’s North and South poles, robbing traditionally poorer countries closer to the Equator of crucial natural resources, US biologists said.
Key species of fish are migrating away from temperate zones and toward the poles as global temperatures rise, Thomson Reuters Foundation reports, citing a study published on Wednesday by a team from Rutgers University, Princeton University, Yale University and Arizona State University.
The migration patterns of fish, a critical food source for millions of people, are likely to exacerbate inequality between the world’s poor and rich, the study said.
The world’s wealthier areas tend to be in cooler regions closer to the poles.
“Natural resources like fish are being pushed around by climate change, and that changes who gets access to them,” Malin Pinsky, one of the study’s authors and a marine biologist, said in a statement.
The study, published in the journal Nature Climate Change, used data on fish migration patterns along with a mathematical formula that tracked the movement of natural resources and shifts in wealth.
