Ocean Resources

What are some examples of renewable ocean resources?

• Wind energy, wave energy, and tidal energy

• Solar energy, geothermal energy, and hydroelectric power

• Coal, oil, and natural gas

• Plastic waste, sewage, and industrial runoff

Explain the concept of aquaculture and its significance in ocean resource management.

• Aquaculture is the farming of aquatic organisms in controlled environments and is significant in providing a sustainable source of seafood and reducing pressure on wild fish stocks.

• Aquaculture is the study of ocean currents and is significant in predicting weather patterns.

• Aquaculture is the process of harvesting seaweed and is significant in reducing pollution in the ocean.

• Aquaculture is the practice of hunting marine mammals and is significant in controlling their population.

What are the potential environmental impacts of offshore oil drilling?

• Oil spills, habitat destruction, air and water pollution, and disturbance to marine life.

• Enhanced marine ecosystems

• Increased biodiversity

• Improved water quality

How do ocean currents contribute to the generation of renewable energy?

• By increasing the salinity of the water, which can be used to generate power

• By driving turbines to generate electricity

• By causing erosion of the ocean floor

• By creating waves that can be harnessed for energy

Discuss the importance of marine biodiversity in sustaining ocean resources.

• Marine biodiversity has no impact on ocean resources

• Marine biodiversity supports ecosystem functions and provides food and habitat for marine species.

• Ocean resources are not affected by the variety of marine species

• Marine biodiversity only affects land resources, not ocean resources

What are the main challenges in sustainable fishing practices?

• Legal fishing practices have no impact

• Impact of overfishing, bycatch, habitat destruction, and illegal, unreported, and unregulated fishing.

• Habitat preservation is not important

• Impact of underfishing

Explain the concept of desalination and its role in addressing water scarcity.

• Desalination only works in areas with abundant freshwater resources

• Desalination is a process of removing salt from ocean water to make it undrinkable

• Desalination helps address water scarcity by providing a source of fresh water in regions with limited access to freshwater resources.

• Desalination has no role in addressing water scarcity

What are the economic benefits of ocean tourism and recreation?

• Decreased employment, reduced income, and limited business growth

• Job creation, revenue generation, and increased local business opportunities

• Negative impact on local culture, increased crime rate, and higher taxes

• Environmental degradation, loss of biodiversity, and pollution

Discuss the impact of plastic pollution on ocean resources.

• Plastic pollution has no impact on ocean resources

• Plastic pollution can lead to entanglement, ingestion, and habitat destruction for marine animals, as well as economic losses for fisheries.

• Plastic pollution helps to improve the ecosystem in the ocean

• Marine animals benefit from plastic pollution

How can sustainable ocean resource management contribute to global food security?

• By ignoring the impact of climate change on ocean resources and food security

• By ensuring the long-term availability of fish and other marine resources for human consumption.

• By depleting the ocean resources to meet the immediate demand for food

• By increasing the use of harmful fishing practices that damage marine ecosystems
