5.3.1 Marine Resources

• Living marine resources include plants, animals, and other organisms
• What roles do marine resources play in human society?

  Food, economy, energy
• What are non-living marine resources essential for?

  Energy and construction
• What are the two main types of marine resources?

  Living and non-living
• Non-living marine resources such as oil and gas are essential for energy generation.


  True
• In fisheries, sustainable management includes implementing quotas, limiting bycatch, and promoting aquaculture
• Threats to marine resources include pollution, overfishing, and climate change.


  True
• Overfishing leads to the depletion of fish stocks and disrupts marine food webs.
• Rising sea temperatures and ocean acidification impact marine species and habitats
• What are the three main threats to marine resources mentioned in the introduction?

  Pollution, overfishing, climate change
• Pollution has no significant effect on marine life and habitats.

  False
• Climate change leads to rising sea temperatures and ocean acidification
• What is the importance of addressing the threats to marine resources?

  Sustainable management and conservation
• What role do marine resources play in food security, economy, and energy production?

  Critical
• Responsible management of marine resources is crucial for ensuring long-term sustainability
• Pollution, overfishing, and climate change harm marine ecosystems and impact coastal communities
• What are marine resources categorized as?

  Living and non-living
• Non-living marine resources include oil, gas, and sand.

  True
• Living marine resources contribute to food security and ecosystems
• Order the following steps to extract marine resources sustainably:

  1️⃣ Employ sustainable fishing practices

  2️⃣ Develop renewable energy sources

  3️⃣ Minimize environmental impact
• Marine resources are critically important for food security, economic development, and energy production
• What are the two key aspects of sustainable management of marine resources?

  Conservation and extraction
• Match the marine sector with its sustainable approach:

  Fisheries ↔️ Implementing quotas

  Energy ↔️ Harnessing offshore wind

  Construction ↔️ Recycling sand and minerals
• What are two examples of pollutants affecting marine resources?

  Oil spills and plastic waste
• What are the effects of rising sea temperatures and ocean acidification on marine ecosystems?

  Habitat destruction, species migration
• Climate change is one of the primary threats to marine resources.


  True
• Pollution can take many forms, including oil spills and plastic waste
• What is the primary cause of the depletion of fish stocks?

  Overfishing
• Ocean acidification reduces the ability of marine organisms to form shells and skeletons.


  True
• Threats to marine resources harm marine ecosystems and impact communities relying on the sea for livelihoods
• Non-living resources like oil and gas are essential for energy generation worldwide.


  True
• What are the key strategies for sustainable management of marine resources?

  Conservation and responsible extraction
• What are the consequences of overfishing on marine ecosystems?

  Depletion of fish stocks
