Question

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

Explanation:

Marine debris sources include land - based activities like improper waste disposal, littering, and runoff carrying trash to the sea. Ocean - based sources are from ships, fishing vessels (lost or discarded gear). It's a global problem as ocean currents spread debris across vast distances. Debris can harm marine life, damage habitats, and impact human activities like fishing and tourism on a global scale.

Answer:

Sources of marine debris: Land - based (improper waste disposal, littering, runoff) and ocean - based (from ships, fishing vessels). It's a global problem because ocean currents spread debris widely and it impacts marine life, habitats, and human activities globally.
