What did the ocean look like before plastic pollutants?
At the Ocean Memory Lab, part of California’s Monterey Bay Aquarium, scientists are undertaking a study of the world’s oceans and marine life before plastic and chemical pollutants were introduced to the water. By studying the feeding habits of seabirds over the course of almost 130 years, they hope to learn how the ocean has changed during that time. Ivette Feliciano reports.
