Why Aren’t We Talking About Ocean Fertilization?

Every so often, an idea comes along that is so simple and effective it feels like a no-brainer—until you realize just how much resistance it faces. That’s exactly what’s happening with ocean fertilization, a method of removing carbon from the atmosphere that should be at the center of climate discussions but instead has been pushed to the fringes.

Quico Toro’s recent article, “The Reason You’ve Never Heard of Ocean Fertilization”, dives into why this promising solution remains so obscure. The short answer? Environmental groups have done a fantastic job of shutting it down before it ever had a chance.

The science behind ocean fertilization is solid. It’s based on the research of oceanographer John Martin, who showed that adding small amounts of iron to iron-deficient parts of the ocean could trigger massive phytoplankton blooms. These blooms not only support marine life but also pull carbon dioxide from the atmosphere and sink it to the ocean floor. In theory, it’s an incredibly efficient and natural way to sequester CO₂.

But here’s where things get complicated. Instead of embracing the potential of this method, organizations like Greenpeace and WWF led the charge against it, warning of possible ecological side effects and claiming it was a dangerous form of geoengineering. Their concerns weren’t entirely baseless—any large-scale intervention in nature has risks—but their opposition effectively stalled progress. The LOHAFEX experiment, a major international attempt to study iron fertilization, was nearly canceled due to these pressures.

This brings up a bigger issue: Why do we allow fear to dictate our response to climate change? The argument that geoengineering solutions like ocean fertilization create a “moral hazard” (because they might distract from emissions reductions) is deeply flawed. We need to throw every viable solution at the climate crisis, and yet, we keep rejecting the ones that don’t fit neatly into the established narrative.

Toro’s piece is a must-read because it challenges the assumption that environmental activism always leads us toward the best solutions. Sometimes, it shuts them down. If we truly care about restoring the climate, we need to question who gets to decide what ideas are worth exploring—and whether we can afford to keep ignoring options like ocean fertilization.

Can Ocean Iron Fertilization (OIF) Drive Economic Development?

From Climate Restoration to Economic Growth

While Ocean Iron Fertilization (OIF) is primarily seen as a climate restoration tool, its economic potential is just as compelling. By stimulating marine productivity, OIF can unlock new revenue streams, create jobs, and revitalize coastal economies.

This article explores how large-scale OIF deployment can:

  • Create thousands of jobs per deployment site across marine industries.
  • Boost global fisheries, increasing seafood supply and income for fishing communities.
  • Develop new industries, from carbon markets to ocean-based biotechnology.
  • Strengthen coastal economies, providing sustainable livelihoods.

How OIF Can Boost the Global Economy

1. Job Creation: Thousands of New Jobs Per OIF Site

At full-scale operation, 60 Gt of CO₂ removal per year would be distributed across 30-50 OIF deployment sites worldwide. Each site would need a dedicated workforce across research, vessel operations, fisheries, and carbon credit management.

A single OIF deployment site is estimated to create:

  • Marine Research & Science: Each site would require oceanographers, climate scientists, and engineers, employing 300-500 people per site.
  • Vessel Operations & Logistics: With multiple vessels per site conducting iron dispersal, monitoring, and maintenance, each site would employ 1,500-2,500 maritime workers.
  • Fisheries & Seafood Industry: Increased fish biomass from OIF would expand local fisheries. Each site could support 20,000-40,000 new jobs in fishing, processing, and distribution.
  • Carbon Credit & MRV (Measurement, Reporting, and Verification): Managing and verifying climate credits would require 500-1,000 financial and regulatory professionals per site.
  • Marine Biotechnology & Innovation: Growth in bio-based industries like algae-derived products and pharmaceuticals would create 200-500 jobs per site.

Across 30-50 sites, global job creation from OIF would be 900,000 to 2.2 million jobs worldwide, depending on the scale of deployment.


2. Enhancing Fisheries and Aquaculture

  • By stimulating phytoplankton blooms, OIF increases fish populations, supporting commercial fisheries.
  • A single OIF site could generate millions of tons of additional fish biomass, supporting thousands of local jobs.
  • Seafood is a $400 billion global industry—enhancing fish stocks means increased profitability for businesses and food security for communities.

3. Creating a Carbon Credit Market

  • OIF removes gigatons of CO₂ from the atmosphere, making it eligible for climate credits.
  • With the carbon market projected to reach $2.4 trillion by 2027, OIF-based credits could become a major revenue stream.
  • Each site could generate millions of carbon credits annually, attracting funding from corporations, governments, and ESG investors.

4. Fueling Marine Biotechnology & Innovation

  • OIF-driven plankton blooms can support new bio-based industries, such as algae-based biofuels, pharmaceuticals, and sustainable fish feed.
  • Each OIF site could serve as a hub for marine innovation, creating spin-off industries in biotechnology.

A Blueprint for Sustainable Economic Growth

OIF is not just an environmental solution—it’s an economic strategy. By scaling up this approach, we can:

Create thousands of jobs per site in ocean-based industries.
Boost global food supply with sustainable fisheries.
Develop new financial opportunities through carbon credits.
Drive innovation in marine-based industries.

Can Climate Restoration Solve Hunger?

The Connection Between Climate and Food Security

Hunger remains one of the most pressing global challenges, and organizations like The Hunger Project and RESULTS have been at the forefront of efforts to eradicate it. The Hunger Project focuses on empowering communities to develop sustainable food systems through grassroots leadership, education, and self-reliance programs¹. RESULTS is a global advocacy organization dedicated to ending poverty by influencing policy changes related to food security, healthcare, and economic opportunity².

Some of our team members are proud graduates of these organizations, and their experience in tackling food insecurity informs our work in climate restoration.

But what if one of the most powerful tools for addressing global hunger isn’t just in agriculture—but in the ocean? And what if restoring the ocean’s natural productivity could help secure nutritious food for billions?

This is the intriguing possibility offered by Ocean Iron Fertilization (OIF).


How OIF Might Boost Fish Populations

OIF works by adding small amounts of iron to nutrient-poor regions of the ocean, stimulating phytoplankton blooms. These microscopic plants capture CO₂ from the atmosphere through photosynthesis, converting it into organic biomass that forms the base of the marine food chain—ultimately feeding zooplankton, small fish, and larger fish species.

So, what could happen if we scaled OIF to its full theoretical potential?

Let’s explore a “what if” scenario to understand the magnitude of the opportunity.


A Hypothetical Calculation: From CO₂ to Fish

1. CO₂ Conversion to Biomass

  • Phytoplankton convert CO₂ into organic matter at roughly 1 ton CO₂ → 2 tons phytoplankton biomass³.
  • Not all of this biomass reaches the upper levels of the food web—some is consumed or recycled at lower levels.

2. Trophic Efficiency and Fish Yield

  • Energy transfer through the marine food chain follows a general 10% rule⁴:
    • 10% of phytoplankton becomes zooplankton
    • 10% of zooplankton becomes small fish
    • 10% of small fish becomes large fish

3. Scaling the Hypothetical Impact of Full OIF Deployment

If OIF were deployed globally to remove 60 Gt of CO₂ annually, we might see:

  • 120 Gt of phytoplankton biomass (at a 2:1 ratio)³
  • 12 Gt of zooplankton biomass
  • 1.2 Gt of small fish biomass
  • 0.12 Gt (120 million tons) of large fish biomass

4. What Could That Mean for Food Security?

The global average fish consumption per person is around 20 kg (44 lbs) per year⁵.

  • In this scenario, 120 million tons of extra large fish could theoretically feed 6 billion people annually.

A Possibility Worth Exploring

Of course, this scenario is based on ideal conditions and simplified assumptions. In the real world, many factors—ecological limits, ocean currents, nutrient cycling, biodiversity impacts, and policy considerations—would influence the actual outcomes of large-scale OIF.

But even if a fraction of this potential is realized, it could transform global food systems. A 10% increase in ocean productivity, for example, could support hundreds of millions of people with additional seafood protein, bolster coastal economies, and provide critical support to regions facing hunger.


The Role of CRA: Restoring the Climate, Regenerating Life

The Climate Restoration Alliance (CRA) is not only advancing Ocean Iron Fertilization (OIF) as a climate solution but also as a bold strategy to support global food security. By coordinating large-scale OIF deployment, CRA works with scientists, policymakers, investors, entrepreneurs, and industry leaders to restore ocean ecosystems and revitalize fisheries.

Through strategic partnerships and funding, CRA ensures that OIF benefits coastal communities, small-scale fishers, and global seafood markets, making abundant, nutritious food more accessible to billions. With the potential to significantly increase the global fish supply, CRA’s leadership in scaling OIF is a key step toward ending hunger while restoring the climate.


Call to Action: Join the Movement

Restoring the climate isn’t just about reducing carbon—it’s about regenerating life. Our Ocean Iron Fertilization (OIF) project has the potential to enhance marine ecosystems, increase fish populations, and help alleviate global hunger.

We’re looking for partners, funders, and advocates to help scale this promising solution. By supporting CRA’s OIF initiative, you’re investing in both climate restoration and food security for future generations.

How a Tiny Amount of Iron Could Reverse Climate Change

Can we restore the climate with a simple, cost-effective process? The math behind ocean iron fertilization (OIF) suggests we can.

In his postPeter Fiekowsky breaks down the astonishing efficiency of OIF—how adding a small amount of iron to specific parts of the ocean can trigger massive phytoplankton blooms that pull CO₂ from the atmosphere. The numbers are staggering:

Key Takeaways:

  1. 1 ton of iron can capture up to 200,000 tons of CO₂.
  2. OIF could scale up to remove 60 gigatons of CO₂ per year, enough to restore pre-industrial levels.
  3. The 1991 eruption of Mt. Pinatubo unintentionally demonstrated OIF’s potential when volcanic ash triggered a phytoplankton bloom, leading to a measurable cooling effect.

At the Climate Restoration Alliance (CRA), we focus on science-backed, scalable solutions that don’t just slow climate change but reverse it. OIF is one of the most promising tools we have to achieve that goal.

Climate Restoration: California OIF/Buoy Test Update

Thank you to those who donated and helped!

Thanks to you we have raised 46% of our $70,000 budget, and purchased the first buoy!

The buoy was picked up last week from San Francisco by Alan, our lead engineer.

In parallel, design work has been happening. Here is Alan inspecting a PTFE membrane after it had been exposed to 18-ft of depth – This is the first time a large membrane (1.5″ pipe with O-ring seal, so about 1.65″ diam circle of exchange area) has survived our 18-ft depth test!

What’s Next:

We plan to finalize a design by late December and then create and install fixturing to mount the detectors on the buoys and integrate them with the satellite communication system.

We will then test this first buoy in January in nearby bodies of water while acquiring the 2nd and 3rd buoys (we need your help for that!).  When those are received, they will be fitted with detectors in preparation for the offshore test sometime in late February.

Climate Restoration Brief #2: Ocean Restoration

Ocean iron fertilization (OIF) appears to be the fastest, safest and most effective climate restoration solution although it was controversial for a time. OIF restores fisheries and other marine life while also reducing CO2 levels at the scale needed to restore the climate. It requires little or no public funding: instead, the process produces revenue and taxes from revived fisheries.
