Sustainable Development Goal 14 – Life Below Water

Sustainable Development Goal 14 (SDG 14), part of the 17 Sustainable Development Goals established by the United Nations, focuses on conserving and sustainably using the oceans, seas, and marine resources for sustainable development. This goal, vital for our planet’s health, directly impacts every individual, from high school and homeschooling students to parents and beyond. Our oceans cover over 70% of the Earth’s surface, and they are key to our climate, livelihoods, and biodiversity.

Top 10 Current Issues Facing Sea Life and Undersea Ecosystems:

  1. Plastic Pollution: Millions of tons of plastic end up in the oceans yearly, posing serious threats to marine life.
  2. Overfishing: Unsustainable fishing practices deplete fish stocks faster than they can replenish.
  3. Climate Change: Rising temperatures and ocean acidification affect coral reefs and marine species.
  4. Habitat Destruction: Coastal development and destructive fishing methods damage crucial marine habitats.
  5. Chemical Pollution: Runoff from agriculture and industries introduces harmful substances into marine ecosystems.
  6. Oil Spills: These disasters cause immediate and long-term damage to marine life and habitats.
  7. Noise Pollution: Underwater noise from human activities disrupts the behavior of marine animals.
  8. Invasive Species: Non-native species can outcompete native marine life, altering ecosystems.
  9. Marine Debris: Besides plastics, other forms of waste also harm marine life and habitats.
  10. Lack of Effective Management: Insufficient policies and enforcement measures fail to protect marine environments.


Preventing and Reducing Marine Pollution:

Effective strategies include:

  1. Land-Based Actions: Implementing stricter waste management policies and promoting recycling to reduce land-based sources of marine pollution.
  2. Education and Awareness: Raising public awareness about the impacts of pollution on marine life.
  3. Policy Implementation: Strengthening and enforcing environmental regulations.
  4. Innovative Technologies: Developing and using technologies to clean up existing pollutants and prevent future pollution.


Sustainable Management of Marine and Coastal Ecosystems:

To avoid adverse impacts, we must:

  1. Protect Marine Habitats: Establishing marine protected areas and restoring damaged ecosystems.
  2. Sustainable Practices: Promoting sustainable fishing and tourism.
  3. Research and Monitoring: Conducting ongoing research to understand ecosystem changes and impacts.
  4. Community Engagement: Involving local communities in conservation and management efforts.


Artisanal Fishers Access to Resources and Markets:

Providing access helps in:

  1. Enhancing Livelihoods: Supporting the economic stability of coastal communities.
  2. Sustainable Practices: Encouraging sustainable fishing practices.
  3. Cultural Preservation: Maintaining traditional fishing methods and cultures.
  4. Food Security: Contributing to local and global food supplies.


Implementing International Law for Ocean Conservation:

World governments and organizations can enhance conservation by:

  1. Adhering to UNCLOS: Fully implementing the United Nations Convention on the Law of the Sea.
  2. International Cooperation: Collaborating on global and regional ocean governance.
  3. Enforcement Mechanisms: Establishing effective enforcement of international laws and agreements.
  4. Supporting Small States: Assisting small island developing states in conservation efforts.


School or Homeschool Learning Ideas


  1. Ocean Pollution Simulation – Conduct a simulation activity where students experience the impact of ocean pollution on marine life. Use real-world examples like plastic pollution in the Great Pacific Garbage Patch or oil spills like the Deepwater Horizon disaster to illustrate the consequences of human activities on marine ecosystems. Through this simulation, students will gain awareness of the importance of protecting life below water and explore solutions for mitigating ocean pollution.
  2. Marine Species Conservation Project – Challenge students to research and develop conservation projects focused on protecting marine species and habitats. Use real-world examples like coral reef restoration efforts or sea turtle conservation programs to inspire students in taking action to safeguard biodiversity in oceans. Students will learn about the importance of preserving marine ecosystems and the role of conservation initiatives in achieving sustainable development goals.
  3. Ocean Acidification Experiment – Conduct an experiment to demonstrate the effects of ocean acidification on marine organisms like corals or shellfish. Use real-world examples like the acidification of oceans due to increased carbon dioxide emissions to illustrate the impact on marine ecosystems. Through this hands-on activity, students will explore the science behind ocean acidification and its implications for marine biodiversity and food security.
  4. Fisheries Management Simulation – Engage students in a fisheries management simulation where they role-play as fishers, scientists, and policymakers tasked with managing marine resources sustainably. Use real-world examples like overfishing in the Atlantic cod fishery or the success of sustainable fisheries management practices in countries like Iceland to inform the simulation. Students will learn about the complexities of balancing economic interests with environmental conservation in fisheries management.
  5. Plastic Waste Recycling Campaign – Empower students to launch a plastic waste recycling campaign in their school or community to raise awareness about the impact of plastic pollution on marine life. Use real-world examples like plastic recycling initiatives and beach clean-up efforts to inspire students to take action in reducing plastic waste and protecting life below water. Through this advocacy project, students will promote sustainable behaviors and contribute to ocean conservation efforts.


What Our Children Need to Know:

  1. The Role of Oceans in Our Climate: How oceans regulate our climate and what happens if this balance is disturbed.
  2. Marine Biodiversity: The variety of life in the oceans and why it matters.
  3. Human Impacts on Oceans: How our actions on land affect marine life.
  4. Conservation Efforts: What is being done and what can young people do to help.
  5. Future of the Oceans: How the health of the oceans affects future generations.


The Big Questions:

  1. How does the health of the oceans affect our daily lives?
  2. What are the biggest threats to marine life today?
  3. How can each individual contribute to ocean conservation?
  4. What role do governments play in protecting the oceans?
  5. Can technology help save our oceans, and if so, how?



Protecting and sustainably using our oceans is not just an environmental issue; it is crucial for our survival and well-being. We need collective action from individuals, communities, and governments worldwide to achieve SDG 14 and ensure a healthy future for our oceans.
