The hypothesis proposed that a greater abundance of land-based marine debris would be observed along the shorelines of sandy beaches.
Is there a significant difference between the abundance of land-based as compared to sea-based sources of marine debris accumulating on beaches along fresh and saltwater shorelines?

Commit more global resources to the protection and restoration of marine ecosystems
Increase research and assessments on the abundance, accumulation rates and impact of marine debris on land and in water
Develop universal action plan to manage human impact Educate and create community awareness on sources of
debris Promote global responsibility Change the culture and encourage citizens to reduce,
reuse, recycle Be proactive and become a part of the solution
