Although considered the most biologically diverse ecosystem in the world, coral reefs（珊瑚礁）are declining rapidly due to overuse, pollution, and warming temperatures. In recent years, the negative impacts of sunscreen （防晒霜）on coral reefs have also raised alarm. While slathering up（涂上厚厚一层）is important if you’re going to be at the beach all day, many people don’t realize that thousands of tons of sunscreen wash off our bodies and into the ocean every year. Once in the water, certain chemicals in sunscreen negatively interact with the surrounding environment. These chemicals have been shown to inhibit coral growth, disrupt coral reproduction, and promote coral viruses.
