Currents could disrupt ocean food chain

A study by Oregon State University suggests that ocean currents could disrupt the marine food chain, leading to a decline in phytoplankton productivity. The Atlantic Conveyer current, which warms Europe, is a critical component of this process, and its disruption could have far-reaching consequences for global food security.
