Plastic pollution in the oceans is a big problem, harming animals and the environment. In Portugal, scientists have been studying plastic debris on beaches since 2008. They found that plastics can absorb harmful chemicals, which can hurt marine life and animals that live near the coast. The researchers also discovered tiny pieces of plastic, called microplastics, in plankton samples. It's important to keep studying this issue to understand how plastic pollution is affecting Portugal's coast.
