Should We Explore the Ocean or Space First? Why the Future Lies Beneath the Waves

Before we race toward the stars, it’s time to look beneath the surface of our own planet. Discover why ocean exploration is vital and full of opportunities.

In April this year, pop star Katy Perry took a trip to space as part of Blue Origin's all-female crew aboard the New Shepard rocket. The 11-minute flight sent them soaring more than 60 miles above Earth, offering a brief experience of weightlessness and a front-row seat to the edge of the cosmos. [1]

Like her, many other celebrities and public figures are joining the 21st-century space race: launching rockets, building private space stations, and even planning future lunar getaways. It’s flashy and futuristic, yet completely unsustainable – and it distracts us from something vital beneath our feet.

Because right here on Earth lies a vast, largely uncharted realm covering over 70% of our planet: the ocean. And although it's crucial to our survival, over 80% of it remains unexplored. [2] So, as Katy Perry said after her trip to space, to truly feel “super connected to life” and “so connected to love,” [3] we need to start uncovering and protecting the wonders right here on our own planet.

4 Key Benefits of Ocean Exploration

Thanks to advances in underwater drones, mapping technology, and remote sensors, studying the ocean is easier than ever… without leaving our planet. Through it, we can achieve different benefits, including:

1. Fighting Climate Change
Oceans produce over 50% of the Earth’s oxygen and absorb massive amounts of heat and carbon dioxide. [4] By exploring and understanding ocean currents, temperatures, and ecosystems, we can develop better strategies to combat climate change, protect coastlines, and improve weather prediction. [5]

2. Unlocking Medical Breakthroughs
Many of today’s medicines come from nature (like aspirin!), and the ocean is the next frontier. Marine animals like sponges, tunicates, and bryozoans produce powerful compounds with antibiotic, anti-inflammatory, and anti-cancer properties. Chemicals like Ecteinascidin and Bryostatin, which may help treat breast cancer and leukemia, were discovered in deep-sea species. [6] With so much marine life still unexplored, the ocean could hold the key to tomorrow’s life-saving treatments.

3. Supporting Global Food and Economic Security
Oceans are a key source of protein for over 3 billion people and provide jobs for millions through fishing, aquaculture, and tourism. [7] By exploring and managing marine resources sustainably, we can protect both biodiversity and livelihoods.

4. Powering Innovation
Challenges in ocean exploration often lead to innovative technologies and engineering solutions, many of which can be used to tackle real-world ocean crises, such as oil spills. Additionally, the ocean holds vast potential as a clean energy source. With further research and development, this energy could supply around 10% of the EU’s power demand by 2050. [9]

Ocean Exploration and Conservation Go Hand in Hand

Exploring the ocean isn’t just about discovery; it’s about safeguarding our future. As Sir David Attenborough says in his latest documentary, “If we save the ocean, we save our world.” [10] The more we understand marine ecosystems, the better we can defend them (and us) against threats.

Volunteers involved in a beach clean-up.

That’s why growing the community of ocean advocates and experts is so important.

Want to Help? Ocean Conservation Jobs Are on the Rise

If you’re passionate about the sea, opportunities go beyond volunteering. Ocean conservation is an expanding field with diverse career paths, including:

Marine Ecologist
Policy and Advocacy Officer
Community Outreach Officer
Geographic Information System (GIS) Spatial Modeller
Marine National Park Ranger
Environmental Educator

You can find more here. From developing apps that track ocean health to leading clean-up initiatives, people are turning their passion for the ocean into meaningful, full-time careers.
