The article discusses the challenges in studying marine pollution and its effects on the environment. Researchers are working on ways to monitor and assess the health of aquatic ecosystems to better understand and address pollution. They are looking at different levels of organisms and factors like geography and seasonality to get a comprehensive view. One key finding is that pollutants can build up in organisms through the food chain, leading to potential harm to animals and humans. This includes new chemicals that can disrupt hormone systems and impact growth and reproduction.
