Jay Sawyer from Chicago illustrates how plastic affects the marine mammals in waters. He found almost 1,800 cases of plastic entanglement or ingestion affecting 40 species since 2009. He went through various studies and revealed that 98% of chicks samples contained plastics and that the quantity of plastic being ingested was increasing over time. Over 90% of seabirds have pieces of plastic in their stomachs. He points that Ingesting plastic may have simply weakened the animal or played no role in its death. Overall, in 82% of the cases, the animals died.
