Natural weathering of rocks is a natural process that does not contribute to ocean pollution.

Plastic pollution in the ocean can have a range of negative impacts on marine life, including ingestion, entanglement, and blocking of sunlight.

Agricultural runoff is the primary source of nutrient pollution in coastal waters, due to the excessive use of fertilizers and manure in farming practices.

Nutrient pollution in coastal waters can lead to harmful algal blooms by providing excessive nutrients for algae growth, increasing water temperature, and reducing oxygen levels in the water.

Stock collapse is the term used to describe the decline in fish populations to a point where they are no longer able to sustain themselves.

Overfishing can lead to reduced biodiversity, increased food insecurity, and economic losses, but it does not improve water quality in coastal areas.

Bycatch is the term used to describe the practice of discarding unwanted fish catch back into the ocean.

Bycatch can contribute to ocean pollution by releasing dead fish into the water, entangling marine animals, and damaging marine habitats.

Non-selective fishing is the practice of using fishing gear that is not selective and catches a wide range of marine life, including non-target species.

Non-selective fishing can contribute to ocean pollution by increasing bycatch, damaging marine habitats, and increasing the risk of entanglement for marine animals.

Illegal fishing is the practice of fishing in areas where fishing is prohibited or restricted.

Illegal fishing can contribute to ocean pollution by increasing bycatch, damaging marine habitats, and undermining efforts to manage and conserve marine resources.

Selective fishing is the practice of using fishing gear that is designed to catch fish in a non-lethal manner.

Selective fishing can contribute to ocean pollution by reducing bycatch, protecting marine habitats, and promoting sustainable fishing practices.

Sustainable fishing is the practice of fishing in a manner that ensures the long-term sustainability of marine resources.
