Describe the sources of marine debris and explain why it is a problem with global origins.

Answer 1

The sources of marine debris can be both land-based and ocean-based. Land-based sources include littering, improper waste disposal, and runoff from land into rivers and oceans. Ocean-based sources include abandoned or lost fishing gear, cargo ships dumping their waste at sea, and oil spills.

Marine debris is a problem with global origins because it is not confined to one particular country or region. The ocean currents can transport debris across vast distances, and as a result, marine debris can affect marine ecosystems and wildlife all over the world. Additionally, marine debris can have economic impacts, such as damage to fishing industries and tourism, which can have ripple effects on communities and nations worldwide. Therefore, it is crucial that the issue of marine debris is addressed by all countries, and global solutions are put in place to mitigate and prevent it.
