• Biomagnification
  Biomagnification: Toxic chemicals and heavy metals flow into the ocean when industrial, agricultural, and human wastes runs off or is deliberately discharged into rivers that then empty into the sea. These pollutants cause disease, genetic mutations, birth defects, reproductive difficulties, behavioral changes, and death in many marine organisms. But the severity of the damage varies greatly between species. In many cases, animals near the top of the food chain are most affected because of a process called biomagnification.
