A policy expert explains why the budget reconciliation bill will harm the ocean and attempts to protect and understand it.
U.S. President Donald Trump is not a fan of sharks or the ocean. From gutting the National Oceanic and Atmospheric Administration, or NOAA, to seeking the expansion of offshore oil drilling and deep-sea mining while attacking wind energy, his view of our public seas is that they'll make a good gas station and garbage dump. And, this view is reflected in his major legacy bill recently passed into law by the MAGA majority in Congress.
But there's been little discussion about how this bill will impact our public seas. So, we (Vicki Nichols Goldman and myself) spoke with George Leonard, former chief scientist with the Ocean Conservancy and an ocean policy consultant about what's going on:
George Leonard (GL): I am a marine scientist by training. I got a master's in marine science and then a PhD in ecology and evolutionary biology and have for 25 years worked on the interface between science and policy. I think many of the moves made by the Trump administration are counter to good public policy and put the ocean at great risk.
David Helvarg (DH): George, during the first Trump administration, his focus seemed to be on opening it up for offshore drilling.
GL: Yeah, I think that's right. Now, on the one hand, it (the Trump administration's new ocean policy) feels disjointed, unorganized, and without a broader strategy. And yet if you then actually try to focus in on what's happening, it seems to be quite deliberate. The attacks on science and knowledge seem to be comprehensive and unrelenting. And that's really troubling, right? It's troubling for a whole generation of upcoming scientists, undergraduates, graduate students, you know, postdocs, people who are just getting started and having the legs cut out from underneath them. And then you combine that with a real disdain for anything related to renewable energy. Obviously, the ocean has a huge role to play in renewable energy.
Vicki Nichols Goldstein (VNG): I'm looking at the bill, and it's astounding that he is proposing a $2.2 billion reduction in NOAA's overall funding.
GL: By one account that I've seen there's 18 different line items, program areas that NOAA focuses on, and 11 of the 18 aren't just cut, they're terminated, like 100% reduction. The remaining (programs) experience a cut of between 20-60%. I mean, there's a lot of narrative around efficiency and (cutting) fraud and waste. But I have yet to see anything that supports these levels of cuts, certainly not in the NOAA space.
DH: And now they're doing major changes to the Magnuson-Stevens Fishery Conservation and Management Act, which has gotten America close to sustainable commercial fishing in federal waters. Fishermen can't be happy with that. Also, abolishing the Coastal Zone Management Act? That's every coastal state working in coordination with the feds to do good planning. What are some of the other really egregious things you saw coming out of this quote "Big Beautiful Bill"?
GL: I kept calling it the reconciliation bill because I refuse to call it the "big beautiful bill." Some I've heard call it the "big ugly bill." But look, the first thing that I think is really troubling is (getting rid of) the Ocean Observatories Initiative, right? That's a bunch of basic research and scientists working on a whole range of ocean-related science. Climate obviously is a big part of that, but also understanding the role of habitats and the importance of biodiversity and fisheries. That's entirely slated to be cut. I don't know how you pursue any kind of science-based work if you're going to reduce that to zero.
DH: That includes 10 laboratories working on climate and weather.
GL: That's right: 10 individual facilities that are to be closed. But the other big science-related piece for NOAA that many folks probably don't know they have is a big ocean observing system where there are literally high-tech buoys and devices deployed both in coastal waters and in offshore waters. They take the temperature, the pulse if you will, of the ocean and by my latest look, this is also slated for termination.
DH: And one of those ocean observing impacts is that it warns people when there are harmful algal blooms, when red tides are coming into Florida for example, when the beaches are going to be shut down. That warning system is gone. The public's being told, "Go swim at your own risk."
VNG: Or eat shellfish without knowing…
GL: Yes, harmful algal blooms can make water unfit to swim in. But they also have big impacts on the shellfish that we eat. And I know shellfish poisoning is nothing to laugh at. It can be extremely dangerous.
DH: I once interviewed a fisheries enforcement agent who demonstrated the effects of paralytic shellfish poisoning. He grabbed his throat and swelled up his tongue in his mouth and started gagging and flopping around on his desk very realistically. That guy's probably been laid off under this plan.
GL: Probably. You know there are other specific aspects of NOAA that are likewise being hobbled here. One is their ocean acidification program. You know burning fossil fuels is doing two things to the ocean. It's making the ocean hotter, and it's making the ocean more acidic. About 90% of the heat generated by climate change from burning fossil fuels ends up in the ocean and along with warming, it's also making the ocean more acidic. And that's simply because CO2 dissolves in water, and NOAA has spearheaded that work and done a lot of work with coastal shellfish farmers and others to address this issue, and that work (with the aquaculture industry) is being cut as well.
VNG: You think about acidification, what's so important is that you need those calcium carbonate ions, and with acidification, they're being reduced. And so, when you think about oysters and muscles and crabs and clams needing that material as basic building blocks, we're looking at enormous hits to the ocean's productivity.
DH: And people's livelihoods. The shellfish industry has become the indicator species for ocean acidification.
GL: And some of the biggest champions to address the broader issue of climate change and how it relates to ocean acidification have been shellfish farmers, particularly shellfish farmers on the West Coast and in the Pacific Northwest.
DH: Now Trump's pushing deep-sea mining, and yet they've terminated NOAA's Ocean Exploration and Research division, which is all about exploring the deep ocean and understanding the places where they want to go and exploit it.
GL: There's all kinds of things like that that don't make sense. There was an executive order (from Trump) a while back about promoting U.S. aquaculture, and yet there's a cut to the (NOAA) aquaculture program in the reconciliation bill. So, what is that? Do we want to support aquaculture or do we want to undermine it? There doesn't seem to be a lot of consistency there.
VNG: It just seems so challenging to follow the logic with this budget.
DH: It's almost vindictive, without logic, taking a chainsaw to places that may need scalpels or may in fact need to be expanded. Most people hearing about the bill are only hearing about it in terms of, "It'll add $3 or $4 trillion to the budget deficit" or "It will take Medicaid away from 12 million people and give tax benefits to the rich." But there's much more there. Like it will also impact our public seas in these many different ways that we're talking about. The Ocean used to be a bipartisan issue.
GL: Yeah, and there've been great examples of bipartisan work in the U.S. on oceans and fisheries and other issues. But when you look at the voting on this bill, it's pretty astounding. I mean, it's hard to ignore the fact that all the Democrats voted against it, and pretty much all the Republicans with a handful of exceptions, voted for it (passing it into law).
VNG: Well, I think we really need to engage with people who care about these issues. When people start linking up national, federal decisions with their own livelihoods, I think that's when people will start realizing, "Hmm, maybe there's an opportunity in the next election cycle to change what's happening."
GL: And of course, the great irony here is that NOAA had an Office of Education, which also is fully terminated. So whatever education and outreach and conversation is going to happen (around the ocean), it doesn't look like it's going to be led by NOAA, at least in the short term.
DH: No, and look at what we're seeing in other frontline agencies. I mean, the Environmental Protection Agency under Trump, they're pushing to shift the market away from a clean energy transition and back to fossil fuels. They are promoting keeping coal-fired power plants open, which is a major source of mercury in tuna. Mercury out of the smoke stacks that precipitates onto the ocean and into the food web. It's crazy. We're literally at a point where market forces favor a transition to cleaner, cheaper energy, including offshore wind, and they're trying to use their political power to shift that balance back to offshore oil and the burning of coal while denying climate science.
If climate change and pollution and biodiversity loss are the big things that we as a society need to be worried about, both here in the U.S. and around the world, the question is, does this bill make any of those better or worse?
I mean democracies don't guarantee environmental improvement, but that never happens under dictatorships. You need to have democracy in order to have good environmental policy. And so, there's this larger issue: Are we moving away from democracy and is that why we're seeing these irrational power- and vengeance-driven attacks on our public seas?
GL: That's the $64,000 question, David. I don't have a great answer for that one. I'm really just a lowly marine scientist by training, but I do think those are important questions for us to ask and it certainly seems like the evidence, at least now, is pointing in that direction. You know, you were talking about renewable energy versus fossil fuels. Maybe we should acknowledge one very small win in the legislative process here. There was part of the bill that was going to put additional taxes on offshore wind and other renewable technologies that was stripped out of the final version of the bill. And what remains is the tax incentives that are the remainder of the Inflation reduction Act from the Biden administration that will not expire until 2027.
It's a minor win, but one I think that was hard fought for and all of these minor improvements that made the big bad bill less bad is because of advocates and public leaders in Congress and folks like yourselves who are bringing these issues to everybody's attention.
VNG: I want to go back to our national marine sanctuaries program, something that's vital for protecting critical habitats and species and yet they're cutting this program by 60%. And that also includes our national monuments (in the ocean). And you are living adjacent to the Monterey Bay National Marine Sanctuary, so how do you feel these impacts are going to affect recovery?
GL: It's super disheartening. It's the underwater equivalent of our national park system, right? America's greatest idea, but underwater. You know, I grew up in Massachusetts and I remember seeing little sea urchins and teeny little plants and a couple of small fish, and I just thought this was the coolest thing. Then I came to California and flopped into a kelp forest out here, and it just blew my mind away. And I was spellbound, right? And, I realized pretty quickly that that kelp forest was just an example of what was in the Monterey Bay National Marine Sanctuary, which was a testament to just the incredible biodiversity and the amazing habitats that we have here.
So, it's really tough to think about what might be the future of that with a sanctuary office that's going to lose its superintendent and employees and people that I went to graduate school with who have made this their life, protecting the coastal ocean here. I've heard, you know, that they're only going to maintain the buoys in the sanctuaries through this bill and cease all on-water operations, which I'm still not sure what that means. I assume that means any kind of research, and they've also made a statement that they're no longer going to consider any new sanctuaries.
Now the National Marine Sanctuaries Act (the law) has a whole process by which new sanctuaries can be nominated and debated. And they're going to shut the door on any future sanctuaries? I think that's a real disservice to the legislation and to the public's ability to identify places that they want to see protected.
DH: So, George, in terms of looking at what the administration is doing with this new bill, what are the two or three ocean impacts that you think the marine conservation community should be focusing on and educating the public around?
GL: If we kind of step way back for a second, why is this a problem for the ocean? It's important to recognize what are the three big threats right now to ocean health.
In very simplistic terms, what's happening is that we're putting too much stuff into the ocean and we're taking too much stuff out of the ocean. So, we're putting in too much carbon, we're putting in too much plastic, we're putting in too many other pollutants, and we're basically taking out too many fish because there is still a global overfishing crisis.
And so, the United Nations has framed this up as sort of a triple planetary crisis where we have climate change, pollution, and biodiversity loss as three separate but connected problems. And they need to be individually addressed, but they also need to be addressed in an integrative way because the ocean is one big connected system.
If climate change and pollution and biodiversity loss are the big things that we as a society need to be worried about, both here in the U.S. and around the world, the question is, does this bill make any of those better or worse? And I think it's not hard to make the argument that for all three of those problems, this bill makes them worse.
DH: And I'd just add that if you love the ocean, you have to love democracy too. And you have to fight like hell to turn the tide here.
GL: Absolutely. This is not a time to give up. I just saw a headline this morning that some of the Republicans have already started to push back a bit on some of the NOAA impacts largely because of advocacy from members of the public. So, you know, while the bill passed and was signed on July 4, we are still, I think, in the early days of what this is actually going to mean on the water. And we need to keep focused on that.
VNG: Looking for more opportunities for the public to get our voices out there and to make sure that we go out and vote and keep the ocean as a priority.
George Leonard (GL): I am a marine scientist by training. I got a master's in marine science and then a PhD in ecology and evolutionary biology and have for 25 years worked on the interface between science and policy.

"We're gambling with both biodiversity and billions in economic value every day that action is delayed," said one expert.
As this year's United Nations Ocean Conference began in France on Monday, scientists published a study showing that another "planetary boundary," or barriers that ensure the Earth is a "safe operating space for humanity," has been crossed.
Researchers said in 2023 that 6 of the 9 boundaries—biogeochemical flows, biosphere integrity, the climate, freshwater, land use, and novel entities—had been crossed. Last year, they issued a "red alert" about ocean acidification, the topic of the new study, Ocean Acidification: Another Planetary Boundary Crossed.
As the U.S. National Oceanic and Atmospheric Administration (NOAA) explains, humanity's burning of fossil fuels and land use changes have caused the concentration of carbon dioxide in the atmosphere to soar, and the ocean absorbs some of it. The resulting chemical interactions make seawater more acidic.
In the new study, scientists from NOAA, Oregon State University, and the United Kingdom's Plymouth Marine Laboratory (PML) wrote that "we improve upon the ocean acidification planetary boundary assessment and demonstrate that by 2020, the average global ocean conditions had already crossed into the uncertainty range of the ocean acidification boundary."
"This analysis was further extended to the subsurface ocean, revealing that up to 60% of the global subsurface ocean (down to 200 m) had crossed that boundary, compared to over 40% of the global surface ocean," they continued. "These changes result in significant declines in suitable habitats for important calcifying species, including 43% reduction in habitat for tropical and subtropical coral reefs, up to 61% for polar pteropods, and 13% for coastal bivalves."
"As our seas increase in acidity, we're witnessing the loss of critical habitats that countless marine species depend on, and this, in turn, has major societal and economic implications."
The study's lead author, North-East Atlantic Ocean Acidification Hub chair and PML professor Helen Findlay, said in a Monday statement that "looking across different areas of the world, the polar regions show the biggest changes in ocean acidification at the surface. Meanwhile, in deeper waters, the largest changes are happening in areas just outside the poles and in the upwelling regions along the west coast of North America and near the equator."
"Most ocean life doesn't just live at the surface—the waters below are home to many more different types of plants and animals. Since these deeper waters are changing so much, the impacts of ocean acidification could be far worse than we thought," Findlay noted. "This has huge implications for important underwater ecosystems like tropical and even deep-sea coral reefs that provide essential habitats and nursing refuge for many species, in addition to the impacts being felt on bottom-dwelling creatures like crabs, sea stars, and other shellfish such as mussels and oysters."
Fellow PML professor and Global Ocean Acidification Observing Network co-chair Steve Widdicombe, who provided the study authors with comments on a draft, said Monday that "ocean acidification isn't just an environmental crisis—it's a ticking time bomb for marine ecosystems and coastal economies."
"As our seas increase in acidity, we're witnessing the loss of critical habitats that countless marine species depend on, and this, in turn, has major societal and economic implications," he warned. "From the coral reefs that support tourism to the shellfish industries that sustain coastal communities, we're gambling with both biodiversity and billions in economic value every day that action is delayed."
The 2024 Planetary Boundaries report showed 6/9 boundaries breached with the 7th, Ocean Acidification, in danger. A new study shows that this too has now been crossed. The implications are huge!onlinelibrary.wiley.com/doi/10.1111/...#climatechange #oceanacidification #planetaryboundaries #oceans

Costa Rica and France are co-hosting the U.N. summit in the French coastal city of Nice this week. The theme is "accelerating action and mobilizing all actors to conserve and sustainably use the ocean."
Greenpeace USA oceans campaign director John Hocevar, who will be attending the meeting, said Monday that "this conference couldn't come at a more critical time. The ocean is reeling from the combined impacts of industrial fishing, plastic pollution, and climate change. And just when bold leadership is most needed, the U.S. has walked away from the global stage, opening the floodgates to destruction through a barrage of Trump administration executive orders that threaten both domestic and international waters."
"We can't afford any more delay," he stressed. "The decisions made in Nice will set the tone for key global efforts to stem the ocean crisis in the coming months, including the plastics treaty, the global ocean treaty, and deep-sea mining talks at the International Seabed Authority. Whether this conference marks a turning point or takes our oceans further down the road to ruin will depend on the strength and ambition of the commitments made by the international community to stand up for science, uphold international law, and advance environmental justice."
"Our updated diagnosis shows that vital organs of the Earth system are weakening, leading to... rising risks of crossing tipping points."
Six of nine planetary boundaries have already been transgressed, and a seventh, for ocean acidification, is on the verge of being breached, according to a major report released Monday.
The 96-page report, produced by the Potsdam Institute for Climate Impact Research (PIK), is the first in a planned series of annual "planetary health checks."
The authors found that safe planetary boundaries had already been crossed for the climate, freshwater, land use, biogeochemical flows, novel entities, and biosphere integrity—in keeping with a study in Science Advances last year. They found a "clear trend towards further transgression"—moving deeper into the danger zone, where irreversible tipping points are more likely to be triggered—in each of the six categories.
"Our updated diagnosis shows that vital organs of the Earth system are weakening, leading to a loss of resilience and rising risks of crossing tipping points," Levke Caesar, a PIK climate physicist lead author of the report, said in a statement that announced a "red alert."
The health check also showed that ocean acidification, a seventh category, has reached a dangerous precipice, putting the foundations of the marine food web at risk. Ocean acidification, which can threaten coral reefs and phytoplankton populations, is caused by the buildup of carbon dioxide from burning fossil fuels and other human activities.
Caesar said a "safe operating space" threshold for acidification could be crossed in the next few years.
"Looking at the current evolution, I'd say it’s really, really difficult to prevent that [boundary] crossing," she told Mongabay.

PIK director Johan Rockström, a co-author of the new report, helped develop planetary boundary research in the late 2000s. In a seminal 2009 paper in Nature, he and his co-authors found that three of the nine boundaries had already been crossed. That number has gradually gone up based on a series of studies over the last decade.
The planet boundary framework, which is often connected to the degrowth movement, emphasizes that the categories are interconnected.
"The interconnectedness of [planetary boundary] processes means that addressing one issue, such as limiting global warming to 1.5°C, requires tackling all of them collectively," the new report says.
Boris Sakschewski, a climate scientist who, along with Caesar, is a lead author of the report said that, "We know that all planetary boundary processes act together and each one needs protection to protect the whole system."
The consequences of continued ocean acidification, which is primarily measured by aragonite saturation, would be severe, the report warns.
Ocean acidification is approaching a critical threshold, with significant declines in surface aragonite saturation, particularly in high-latitude regions like the Arctic and Southern Ocean. These areas are vital for the marine carbon pump and global nutrient cycles, which support marine productivity, biodiversity, and global fisheries. The growing acidification poses an increasing threat to marine ecosystems, especially those reliant on calcium carbonate for shell formation.
Some researchers believe that the ocean acidification threshold has already been crossed, especially given regional variability, with cooler polar waters absorbing more carbon dioxide, causing a faster drop in pH levels.
The report was written with a general audience in mind and is not peer-reviewed, though it's based on peer-reviewed studies, the authors said.
The final pages of the report present solutions, especially agricultural. A radical overhaul of the global food system, heavily dependent on fertilizer and other harmful inputs, will be necessary to reverse the disturbing trends documented in the report, the authors wrote.
"Sometimes overlooked compared to the impacts of energy production and consumption—particularly the use of fossil fuels—the food systems we depend on are among the largest drivers of environmental degradation. The global food system is the single largest driver behind the transgression of multiple planetary boundaries," the report says.
