Today, in our environmental science lecture, we will discuss the impact of plastic pollution on marine life. Recent studies have shown that over 700 species of marine animals are affected by plastic debris, either through ingestion or entanglement. For example, sea turtles often mistake plastic bags for jellyfish, which can lead to fatal blockages in their digestive systems. Additionally, microplastics, which are pieces smaller than five millimeters, have been found in the stomachs of fish that we consume. This not only harms the animals but also poses a potential risk to human health through the food chain. However, there is hope: many countries have implemented bans on single-use plastics, and innovative cleanup technologies are being developed to remove waste from the oceans.
