Ocean Pollution and Food Security
This quiz aims to assess your understanding of the relationship between ocean pollution and food security.
Questions
Which of the following is NOT a major source of ocean pollution?
- Plastic waste
- Oil spills
- Fertilizers from agriculture
- Natural weathering of rocks
How does plastic pollution in the ocean affect marine life?
- It can be ingested by marine animals, causing health problems.
- It can entangle marine animals, leading to injury or death.
- It can block sunlight from reaching underwater plants, affecting the food chain.
- All of the above
What is the primary source of nutrient pollution in coastal waters?
- Industrial wastewater
- Agricultural runoff
- Sewage discharge
- Atmospheric deposition
How does nutrient pollution in coastal waters lead to harmful algal blooms?
- It provides excessive nutrients for algae growth.
- It increases water temperature, promoting algal growth.
- It reduces oxygen levels in the water, favoring algal growth.
- All of the above
What is the term used to describe the decline in fish populations due to overfishing?
- Bycatch
- Overexploitation
- Depletion
- Stock collapse
Which of the following is NOT a consequence of overfishing?
- Reduced biodiversity in marine ecosystems
- Increased food insecurity in coastal communities
- Economic losses for fishing industries
- Improved water quality in coastal areas
What is the term used to describe the practice of discarding unwanted fish catch back into the ocean?
- Bycatch
- Ghost fishing
- Illegal fishing
- Overfishing
How does bycatch contribute to ocean pollution?
- It releases dead fish into the water, increasing nutrient levels.
- It entangles marine animals, leading to injury or death.
- It damages marine habitats, reducing biodiversity.
- All of the above
What is the term used to describe the practice of using fishing gear that is not selective and catches a wide range of marine life, including non-target species?
- Bycatch
- Ghost fishing
- Illegal fishing
- Non-selective fishing
How does non-selective fishing contribute to ocean pollution?
- It increases bycatch, leading to the release of dead fish into the water.
- It damages marine habitats, reducing biodiversity.
- It increases the risk of entanglement for marine animals.
- All of the above
What is the term used to describe the practice of fishing in areas where fishing is prohibited or restricted?
- Bycatch
- Ghost fishing
- Illegal fishing
- Overfishing
How does illegal fishing contribute to ocean pollution?
- It increases bycatch, leading to the release of dead fish into the water.
- It damages marine habitats, reducing biodiversity.
- It undermines efforts to manage and conserve marine resources.
- All of the above
What is the term used to describe the practice of using fishing gear that is designed to catch fish in a non-lethal manner?
- Bycatch
- Ghost fishing
- Selective fishing
- Sustainable fishing
How does selective fishing contribute to ocean pollution?
- It reduces bycatch, minimizing the release of dead fish into the water.
- It protects marine habitats, preserving biodiversity.
- It promotes sustainable fishing practices, reducing pressure on marine resources.
- All of the above
What is the term used to describe the practice of fishing in a manner that ensures the long-term sustainability of marine resources?
- Bycatch
- Ghost fishing
- Sustainable fishing
- Selective fishing
