Ocean Sustainability

Balancing Prosperity and Protection

Approaching the topic of “ocean sustainability” can be a rather sensitive endeavor. One reason for this is that there doesn’t seem to be a single accepted definition of the term “sustainability.”  So, depending on your scientific, political, or environmental leaning, the meaning of sustainability in general, and ocean sustainability, in particular, can vary depending on who is using the term and in what context it is being used. Another reason is that the very idea of using the ocean’s resources for our benefit –  no matter how well managed – is neither universally accepted nor supported. But with over three billion people’s livelihoods directly dependent on coastal and marine ecosystems[1], it would be unrealistic to think we could ever completely step away from our dependence on the ocean.

While there is no universal definition of sustainability, an often quoted definition comes from the UN World Commission on Environment and Development: “sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”[2] Ocean sustainability, then, is all about approaching ocean management in a way that protects the ocean and the services it provides.[3] It is, in short, a balancing act between what is good for the health and well-being of the ocean and what is good for the economic well-being of those who are dependent on the ocean. Ocean sustainability requires the “use of ocean resources in ways that preserve the health and resilience of marine ecosystems and improves livelihoods and jobs, balancing protection and prosperity.”[4]

Life Under Water

In 2015, the United Nations adopted the Sustainable Development Goals. The adoption of the 17 Sustainable Development Goals was a universal call to action to end poverty, protect the planet, and ensure that by 2030 all people enjoy peace and prosperity. Sustainable Development Goal 14 is “Conserve and sustainably use the oceans, seas and marine resources” or, more colloquially, “Life Under Water.” Goal 14 sets forth ten specific targets to be reached:

14.1 Reduce Marine Pollution. By 2025, prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution

14.2 Protect and Restore Ecosystems. By 2020, sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans

14.3 Reduce ocean acidification. Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels

14.4 Fish stocks within sustainable levels. By 2020, effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics

14.5 Protected Marine Areas. By 2020, conserve at least 10 per cent of coastal and marine areas, consistent with national and international law and based on the best available scientific information

14.6 Combat Illegal, Unreported and Unregulated Fishing. By 2020, prohibit certain forms of fisheries subsidies which contribute to overcapacity and overfishing, eliminate subsidies that contribute to illegal, unreported and unregulated fishing and refrain from introducing new such subsidies, recognizing that appropriate and effective special and differential treatment for developing and least developed countries should be an integral part of the World Trade Organization fisheries subsidies negotiation

14.7 Income from Sustainable Fisheries. By 2030, increase the economic benefits to Small Island developing States and least developed countries from the sustainable use of marine resources, including through sustainable management of fisheries, aquaculture and tourism

14.A Research Resources for Marine Technology. Increase scientific knowledge, develop research capacity and transfer marine technology, taking into account the Intergovernmental Oceanographic Commission Criteria and Guidelines on the Transfer of Marine Technology, in order to improve ocean health and to enhance the contribution of marine biodiversity to the development of developing countries, in particular small island developing States and least developed countries

14.B Support Small Scale Fishers. Provide access for small-scale artisanal fishers to marine resources and markets

14.C Implementing International Sea Law. Enhance the conservation and sustainable use of oceans and their resources by implementing international law as reflected in UNCLOS, which provides the legal framework for the conservation and sustainable use of oceans and their resources, as recalled in paragraph 158 of The Future We Want [5]

Why It Matters

Health and Well-Being

A healthy ocean is essential to our existence. Whether we live near the coast or far from the ocean’s shores, the ocean impacts the health and well-being of every one of us. Consider these facts:

  • The ocean generates over half the oxygen we breathe.[6]
  • The ocean is the largest biosphere on Earth.[7]
  • The ocean contains 97% of Earth’s water.[8]
  • The ocean is home to 50 – 80% of all life on Earth.[9]
  • The ocean plays a crucial role in regulating our climate and weather.[10]
  • The ocean provides nearly 3 billion people with their primary source of protein.[11]

Economic Impact

The ocean also has an enormous impact on both the U.S. domestic and global economies. While the value of the ocean and its resources is incalculable, snapshots of different areas of the ocean economy show that:

  • Over 3 billion people’s livelihoods depend directly on coastal and marine ecosystems.[12]
  • The market value of ocean resources and industries is estimated at $3 trillion per year or about 5 percent of global GDP.[13]
  • Marine fisheries directly or indirectly employ over 200 million people.[14]
  • About 80% of all tourism takes place in coastal areas.[15]
  • 90% of international freight involves marine transporta[16]

An Ocean at Risk

But with less than 3% of the ocean protected, the ocean is at grave risk. Specifically:

  • By 2050 there will be more plastic than fish in the ocean.[17]
  • The ocean has absorbed over 90% of the excess heat trapped by man-made greenhouse gases.[18]
  • Ocean heat is now at record levels, causing widespread marine heatwaves.[19]
  • The sea level has risen over 8 inches since 1880 (with about 3 of those inches gained in the last 25 years).[20]
  • Every year, an estimated 5 to 12 million metric tons of plastic enter the ocean.[21]
  • The ocean has become more acidic due to the absorption of increased levels of atmospheric carbon dioxide. [22]
  • Global fish stocks are being depleted, and marine life is decimated by overfishing. [23]

Ocean Sustainability and Marine Conservation

While these two very important concepts certainly overlap, they should not be considered the same thing. And depending on where you fall on the conservation-sustainability spectrum, the amount of overlap is going to vary greatly. As mentioned above, there are certain marine conservationists that are completely against using the resources of the ocean, sustainable or not. And there are others that see ocean sustainability as an integral part of the marine conservation landscape. One way of looking at how these two areas fit together is to consider marine conservation as one-half of the ocean sustainability equation. Conservation traditionally involves “the preservation, protection, or restoration of the natural environment or natural ecosystem.”[24] Those that advocate for ocean sustainability would wholeheartedly agree with this goal, but not at the expense of the economic well-being of the billions of people who are dependent on the resources the ocean has to offer.

Life Under Water (Revisited)

Returning to Life Under Water (Sustainable Development Goal 14), the preamble to the list of goals sums up the ocean sustainability issue quite nicely:

“The ocean drives global systems that make the Earth habitable for humankind. Our rainwater, drinking water, weather, climate, coastlines, much of our food, and even the oxygen in the air we breathe, are all ultimately provided and regulated by the sea.  Careful management of this essential global resource is a key feature of a sustainable future. However, at the current time, there is a continuous deterioration of coastal waters owing to pollution, and ocean acidification is having an adversarial effect on the functioning of ecosystems and biodiversity. This is also negatively impacting small scale fisheries. Saving our ocean must remain a priority. Marine biodiversity is critical to the health of people and our planet. Marine protected areas need to be effectively managed and well-resourced and regulations need to be put in place to reduce overfishing, marine pollution and ocean acidification.”[25]

Undergraduate Degree

While a college degree is not required for engaging in ocean sustainability activities, obtaining your bachelor’s degree will give you a greater chance of securing paid employment. You can go the science route or the law/policy route or perhaps even pursue both.  But even if you opt for a non-scientific career path, familiarity with the science of marine conservation, sustainable development, marine biology, oceanography, or any climate change science is advisable.

Graduate Degree

If you are pursuing the scientific aspects of ocean sustainability, a master’s degree will open up more employment opportunities. A doctoral degree is required for a career in academia as well as for senior positions in both the government and private sectors. Graduating from law school or obtaining a graduate degree in sustainability or conservation studies is essential for advancement in the non-scientific areas of ocean sustainability.

Tip 1

We could not find one school with a specific ocean sustainability major. Find a school with a sustainable development or sustainable studies program and combine it with a marine science to develop your own area of expertise.

Tip 2

Even if you decide to go the business, environmental law, or public policy route in school instead of the pure science route, you should still develop a strong background in sustainability, conservation, or one of the areas of marine science.

Tip 3

You need to learn how to network. Internships and volunteering are both excellent ways to create connections with potential employers, evidence your unique set of skills, and show off your commitment to sustainability.
