What future design approaches might ensure watercraft resiliency against the unpredictability of ocean plastic pollution and its impact on marine navigation?

ANSWER: Future watercraft could incorporate resilient designs with reinforced hull materials resistant to abrasion from ocean plastics and integrated waste collection systems for capturing debris. Antifouling coatings might be further developed to shed trapped plastics, and advanced sensors could help in detecting and navigating around high-concentration pollution zones. Propulsion systems could be adapted to handle plastic ingestion, and collaborative initiatives could establish removal efforts in critical areas, reducing risks to navigation and the marine ecosystem.
