It’s time to strike an environmental grand bargain between businesses, governments and conservationists – and stop doing things the hard way

It shouldn’t take sustained public outrage to stop environmentally destructive projects. Nature positive offers us a way forward.

April has been a bad month for the Australian environment. The Great Barrier Reef was hit, yet again, by intense coral bleaching. And Environment Minister Tanya Plibersek delayed most of her Nature Positive Plan reforms.

True, Plibersek did reject the controversial Toondah Harbour proposal, but only after a near decade-long grassroots campaign to save the wetland from an apartment and retail development deemed clearly unacceptable by her own department.

Rather than fall back into old patterns of developers versus conservationists, we have a rare chance to find a compromise. Labor’s embrace of “Nature Positive” – a promising new environmental restoration approach – opens up the possibility of a grand bargain, whereby developers and business get much faster approvals (or rejections) in exchange for ensuring nature as a whole is better off as a result of our activities.

Meanwhile, our ecosystems have continued to go downhill. And in a 2020 review of the laws, Graeme Samuel pronounced the EPBC Act a failure.

Nature, positive?

When Labor was elected in 2022, it promised a new goal: “Nature Positive”.

This idea is no mere slogan. Nature positive is a serious policy idea. Think of it as the biodiversity counterpart to net zero emissions.

The goal is ambitious: stop the decline by 2030 and set about restoring what has been lost for a full recovery of nature by 2050. Rather than ticking boxes on whether principles had been considered, regulators would answer a much more basic question: will this development deliver a net positive outcome for nature?

Measuring progress is core to nature positive. We would take an environmental snapshot at the outset and track the gains and losses from there.

Like sustainable development before it, nature positive has been adopted with gusto by the Australian government, internationally and domestically.

In 2022, Plibersek committed to “stop the slide” and to “bake [the Nature Positive reforms] into law”.

Now, suddenly, we have lost momentum. The crucial part of the reforms – embedding nature positive in stronger environment laws – has been kicked down the road.

Plibersek has blamed complexity, extensive consultation and the need to get it right. Others see political concerns.

Could we strike a grand environmental bargain?

By pushing these laws back, Plibersek has effectively turned the already extended consultation process into an open-ended negotiation. Given consultation will keep running indefinitely, we’re now in the realm of regulatory co-design, previously only on offer to First Nations representatives for new cultural heritage protection laws.

Co-design implies proceeding by consensus. It would be politically embarrassing to run a consultation over years only to bring down the policy guillotine.

Consensus in turn raises the possibility of a grand environmental bargain, built around nature positive. Could this work? Might environment groups settle for a limited form of nature positive? Might business, in return for much faster approvals or rejections, support much stronger legal protection, especially for particularly vulnerable or important ecosystems?

Samuel certainly thinks so. At a recent Senate Inquiry, he recounted telling a meeting during his review:

What might an 80% agreement look like?

If we are to turn decline into recovery, we need to ensure each natural system is intact. That is, it retains the minimum level of environmental stocks (such as animals, plants and insects) and flows (such as water, nutrients) needed to sustain ecological health.

Colorado mandates ambitious emissions cuts for its gas utilities

Colorado just set a major new climate goal for the companies that supply homes and businesses with fossil gas. By 2035, investor-owned gas utilities must cut carbon pollution by 41% from 2015 levels, the Colorado Public Utilities Commission decided in a 2–1 vote in mid-November.

Colorado just set a major new climate goal for the companies that supply homes and businesses with fossil gas. By 2035, investor-owned gas utilities must cut carbon pollution by 41% from 2015 levels, the Colorado Public Utilities Commission decided in a 2–1 vote in mid-November. The target — which builds on goals already set for 2025 and 2030 — is far more consistent with the state’s aim to decarbonize by 2050 than the other proposals considered. Commissioners rejected the tepid 22% to 30% cut that utilities asked for and the 31% target that state agencies recommended. Climate advocates hailed the decision as a victory for managing a transition away from burning fossil gas in Colorado buildings. “It’s a really huge deal,” said Jim Dennison, staff attorney at the Sierra Club, one of more than 20 environmental groups that advocated for an ambitious target. ​“It’s one of the strongest commitments to tangible progress that’s been made anywhere in the country.” In 2021, Colorado passed a first-in-the-nation law requiring gas utilities to find ways to deliver heat sans the emissions. That could entail swapping gas for alternative fuels, like methane from manure or hydrogen made with renewable power. But last year the utilities commission found that the most cost-effective approaches are weatherizing buildings and outfitting them with all-electric, ultraefficient appliances such as heat pumps. These double-duty devices keep homes toasty in winter and cool in summer. The clean-heat law pushes utilities to cut emissions by 4% from 2015 levels by 2025 and then 22% by 2030. But Colorado leaves exact targets for future years up to the Public Utilities Commission. Last month’s decision on the 2035 standard marks the first time that regulators have taken up that task. Gas is still a fixture in the Centennial State. About seven out of 10 Colorado households burn the fossil fuel as their primary source for heating, which accounts for about 31% of the state’s gas use. If gas utilities hit the new 2035 mandate, they’ll avoid an estimated 45.5 million metric tons of greenhouse gases over the next decade, according to an analysis by the Colorado Energy Office and the Colorado Department of Public Health and Environment. They’d also prevent the release of hundreds more tons of nitrogen oxides and ultrafine particulates that cause respiratory and cardiovascular problems, from asthma to heart attacks. State officials predicted this would mean 58 averted premature deaths between now and 2035, nearly $1 billion in economic benefits, and $5.1 billion in avoided costs of climate change. “I think in the next five to 10 years, people will be thinking about burning fossil fuels in their home the way they now think about lead paint,” said former state Rep. Tracey Bernett, a Democrat who was the prime sponsor of the clean-heat law. Competing clean-heat targets Back in August, during proceedings to decide the 2035 target, gas utilities encouraged regulators to aim low. Citing concerns about market uptake of heat pumps and potential costs to customers, they asked for a goal as modest as 22% by 2035 — a target that wouldn’t require any progress at all in the five years after 2030. Climate advocates argued that such a weak goal would cause the state to fall short on its climate commitments. Nonprofits the Sierra Club, the Southwest Energy Efficiency Project, and the Western Resource Advocates submitted a technical analysis that determined the emissions reductions the gas utilities would need to hit to align with the state’s 2050 net-zero goal: 55% by 2035, 74% by 2040, 93% by 2045, and, finally, 100% by 2050. History suggests these reductions are feasible, advocates asserted.

The rewriting of Australia’s nature laws come as a relief, yet I can’t help feel a sense of foreboding | Georgina Woods

The minister says quick approvals can happen while protecting the environment, but my experience tells me that haste brings unintended consequencesGet our breaking news email, free app or daily news podcastI got a text from a biodiversity advocate around midday on Thursday asking me: are you glad, or sad?I wasn’t sure how to reply. Continue reading...

I got a text from a biodiversity advocate around midday on Thursday asking me: are you glad, or sad?I wasn’t sure how to reply.The Australian parliament is amending the country’s environment laws. Thanks to negotiating by the Greens, the amended laws will not enable the fast-tracking of coal and gas mining, which the government had proposed. Decisions about coal and gas mines that harm water resources will be retained by the commonwealth and not given over wholly to state governments as the government had proposed. That is an enormous relief.And yet, I am filled with foreboding.The bill introduced into parliament only a few weeks ago proposed to take the country backwards in environmental protection. It sought to strip communities of participation in environmental decisions, hand decision-making about environmental harm to the states and territories and give the environment minister sweeping power to tailor environmental regulations for certain developments, companies or industries.The government made it clear from the outset that the convenience of business, the desire for “quick yesses” that could harm the natural environment, was its chief priority. It has been made clear that the government intends to grant fast-tracked approval to renewable energy developments and minerals mines. There is excited talk about “abundance” – which is code for sweeping forests, wetlands, woodlands and local communities out of the path of business, mining and development.The minister is adamant this can be done while protecting the environment, but my 25 years of experience with environmental regulation tell me that haste brings unintended consequences. It makes communities angry. It leads to losses of our beautiful natural heritage that are mourned for generations. It impoverishes us by eroding the natural ecosystems that actually create the “abundance” that makes our society.Sign up: AU Breaking News emailThere is no abundance without reciprocity and we will learn this, to our sorrow, in the years to come if we continue treating the natural world as a magic pudding that can be cut and cut and cut and will come again.Coal and gas mining will not be fast-tracked and for that I am very glad. But the government ruled out embedding any formal consideration of the impacts of greenhouse gas pollution, the effect of climate change on Australia’s natural heritage, into decision-making. Only a few months ago, Australia’s first national climate risk assessment itemised a devastating prognosis for Australia’s marine, freshwater and terrestrial ecosystems across the continent if global warming exceeds the limits set down in the Paris climate agreement. It spoke of ecosystems collapsing and whole species dying out. The only way to prevent that warming is to stop the pollution that comes from burning coal, gas and oil for energy, and quickly. Indeed, an International Court of Justice advisory opinion has affirmed that all countries have a legal obligation to prevent climate harm and protect the climate system. For Australia, that means preventing the pollution from our energy exports.The greenhouse gas emissions from Australia’s energy exports, and the impact that this pollution is having on Australians, is not going to go away because the minister refuses to think about it, or because the prime minister is too squeamish to talk about it. The consequences will plague our descendents for generations to come, long after this generation of politicians are gone, but there will be more immediate demands from communities suffering the effects of climate change that will become increasingly impossible to ignore.

Mind, hand, and harvest

A volunteer-driven pilot program brings low-cost organic produce to the MIT community.

On a sunny, warm Sunday MIT students, staff, and faculty spread out across the fields of Hannan Healthy Foods in Lincoln, Massachusetts. Some of these volunteers pluck tomatoes from their vines in a patch a few hundred feet from the cars whizzing by on Route 117. Others squat in the shade cast by the greenhouse to snip chives. Still others slice heads of Napa cabbage from their roots in a bed nearer the woods. Everything being harvested today will wind up in Harvest Boxes, which will be sold at a pop-up farm stand the next day in the lobby of the Stata Center back on the MIT campus.This initiative — a pilot collaboration between MIT’s Office of Sustainability (MITOS), the MIT Anthropology Section, Hannan Healthy Foods, and the nascent MIT Farm student organization — sold six-pound boxes of fresh, organic produce to the MIT community for $10 per box — half off the typical wholesale price. The weekly farm stands ran from Sept. 15 through Oct. 27.“There is a documented need for accessible, affordable, fresh food on college campuses,” says Heather Paxson, William R. Kenan, Jr. Professor of Anthropology and one of the organizers of the program. “The problems for a small farmer in finding a sufficient market … are connected to the challenges of food insecurity in even wealthy areas. And so, it really is about connecting those dots.”Through the six weeks of the project, farm stand shoppers purchased more than 2,000 pounds of fresh produce that they wouldn’t otherwise have had access to. Hannan, Paxson, and the team hope that this year’s pilot was successful enough to continue into future growing seasons, either in this farm stand form or as something else that can equally serve the campus community.“This year we decided to pour our heart, soul, and resources into this vision and prove what’s possible,” says Susy Jones, senior sustainability project manager at MITOS. “How can we do it in a way that is robust and goes through the official MIT channels, and yet pushes the boundaries of what’s possible at MIT?”A growing ideaMohammed Hannan, founder of Hannan Healthy Foods, first met Paxson and Jones in 2022. Jones was looking for someone local who grew vegetables common in Asian cuisine in response to a student request. Paxson wanted a small farm to host a field trip for her subject 21A.155 (Food, Culture and Politics). In July, Paxson and Jones learned about an article in the Boston Globe featuring Hannan as an example of a small farmer hit hard by federal budget cuts.They knew right away they wanted to help. They pulled in Zachary Rapaport and Aleks Banas, architecture master’s students and the co-founders of MIT Farm, an organization dedicated to getting the MIT community off campus and onto local farms. This MIT contingent connected with Hannan to come up with a plan.“These projects — when they flow, they flow,” says Jones. “There was so much common ground and excitement that we were all willing to jump on calls at 7 p.m. many nights to figure it out.”After a series of rapid-fire brainstorming sessions, the group decided to host weekly volunteer sessions at Hannan’s farm during the autumn growing season and sell the harvest at a farm stand on campus.“It fits in seamlessly with the MIT motto, ‘mind and hand,’ ‘mens et manus,’ learning by doing, as well as the heart, which has been added unofficially — mind, hand, heart,” says Paxson.Jones tapped into the MITOS network for financial, operational, student, and city partners. Rapaport and Banas put out calls for volunteers. Paxson incorporated a volunteer trip into her syllabus and allocated discretionary project funding to subsidize the cost of the produce, allowing the food to be sold at 50 percent of the wholesale price that Hannan was paid for it.“The fact that MIT students, faculty, and staff could come out to the farm, and that our harvest would circulate back to campus and into the broader community — there’s an energy around it that’s very different from academics. It feels essential to be part of something so tangible,” says Rapaport.The volunteer sessions proved to be popular. Throughout the pilot, about 75 students and half a dozen faculty and staff trekked out to Lincoln from MIT’s Cambridge, Massachusetts, campus at least once to clear fields and harvest vegetables. Hannan hopes the experience will change the way they think about their food.“Harvesting the produce, knowing the operation, knowing how hard it is, it’ll stick in their brain,” he says.On that September Sunday, second-year electrical engineering and computer science major Abrianna Zhang had come out with a friend after seeing a notification on the dormspam email lists. Zhang grew up in a California suburb big on supporting local farmers, but volunteering showed her a different side of the job.“There’s a lot of work that goes into raising all these crops and then getting all this manual labor,” says Zhang. “It makes me think about the economy of things. How is this even possible … for us to gain access to organic fruits or produce at a reasonable price?”Setting up shopSince mid-September, Monday has been Farm Stand day at MIT. Tables covered in green gingham tablecloths strike through the Stata Center lobby, holding stacks of cardboard boxes filled with produce. Customers wait in line to claim their piece of the fresh harvest — carrots, potatoes, onions, tomatoes, herbs, and various greens.Many of these students typically head to off-campus grocery stores to get their fresh produce. Katie Stabb, a sophomore civil and environmental engineering major and self-proclaimed “crazy plant lady,” grows her own food in the summer, but travels far from campus to shop for her vegetables during the school year. Having this stand right at MIT gives her time back, and she’s been spreading the news to her East Campus dorm mates — even picking boxes up for them when they can’t make it themselves and helping them figure out what to do with their excess ingredients.“I have encountered having way too many chives before, but that’s new for some folks,” she says. “Last week we pooled all of our chives and I made chive pancakes, kind of like scallion pancakes.”Stabb is not alone. In a multi-question customer survey conducted at the close of the Farm Stand season, 62 percent of respondents said the Harvest Box gave them the chance to try new foods and 49 percent experimented with new recipes. Seventy percent said this project helped them increase their vegetable intake.Nearly 60 percent of the survey respondents were graduate students living off campus. Banas, one of the MIT Farm co-leads, is one of those grad students enjoying the benefits.“I was cooking and making food that I bought from the farm stand and thought, ‘Oh, this is very literally influencing my life in a positive way.’ And I’m hoping that this has a similar impact for other people,” she says.The impact goes beyond the ability of students to nourish themselves with fresh vegetables. New communities have grown from this collaboration. Jones, for example, expanded her network at MITOS by tapping into expertise and resources from MIT Dining, the Vice President for Finance Merchant Services, and the MIT Federal Credit Union.“There were just these pockets of people in every corner of MIT who know how to do these very specific things that might seem not very glamorous, but make something like this possible,” says Jones. “It’s such a positive, affirming moment when you’re starting from scratch and someone’s like, ‘This is such a cool idea, how can I help?’”Strengthening communityInviting people from MIT to connect across campus and explore beyond Cambridge has helped students and employees alike feel like they’re part of something bigger.“The community that’s grown around this work is what keeps me so engaged,” says Rapaport. “MIT can have a bit of a siloing effect. It’s easy to become so focused on your classes and academics that your world revolves around them. Farm club grew out of wanting to build connections across the student body and to see ourselves and MIT as part of a larger network of people, communities, and relationships.”This particular connection will continue to grow, as Rapaport and Banas will use their architectural expertise to lead a design-build team in developing a climate-adaptive and bio-based root cellar at Hannan Healthy Foods, to improve the farm’s winter vegetable storage conditions. Community engagement is an ethos Hannan has embraced since the start of his farming journey in 2018, motivated by a desire to provision first his family and then others with healthy food.“One thing I have done over the years, I was not trying to do farming by myself,” he says. “I always reached out to as many people as I could. The idea is, if community is not involved, they just see it as an individual business.”It’s why he gifts his volunteers huge bags of tomatoes at the end of a shift, or donates some of his harvest to food banks, or engages an advisory committee of local residents to ensure he’s filling the right needs.“There’s a reciprocal dimension to gifting that needs to continue,” says Paxson. “That is what builds and maintains community — it’s classic anthropology."And much of what’s exchanged in this type of reciprocity can’t be charted or graded or marked on a spreadsheet. It’s cooking pancakes with dorm mates. It’s meeting and appreciating new colleagues. It’s grabbing a friend to harvest cabbage on a beautiful autumn Sunday.“Seeing a student who volunteered over the weekend harvesting chives come to the market on Monday and then want to take a selfie with those chives,” says Jones. “To me, that’s a cool moment.”

Have we found a greener way to do deep-sea mining?

There are widespread concerns that deep-sea mining for metals will damage fragile ecosystems. But if mining ever goes ahead, hydrogen plasma could shrink the carbon footprint of smelting the metal ores

Seafloor covered with manganese nodulesScience History Images/Alamy A process to extract metals from their ore with hydrogen could make deep-sea mining for valuable materials more sustainable than mining on land, a new study claims. Swathes of the ocean floor are littered with nodules the size of tennis balls. These polymetallic nodules are comprised largely of manganese, with smaller amounts of nickel, copper and cobalt, as well as other elements. As the construction of solar power and electric vehicles booms, demand for these metals is increasing because they are vital components of batteries and wiring. But plans to mine for the polymetallic nodules are highly controversial because operations to collect them would potentially harm the deep-sea floor – one of the last pristine ecosystems on Earth. Even so, some researchers suspect that deep-sea extraction will eventually take place. “I think there is a good chance that someday people… will mine the nodules,” says Ubaid Manzoor at the Max Planck Institute for Sustainable Materials in Germany. “So better to have a good process [for extracting metals] after mining than to have one more dirty process.” The Metals Company, a Canadian deep-sea mining company that has applied for a deep-sea mining permit from the Trump administration, plans to extract metals using a fossil fuel-based approach involving coke and methane. Its process involves placing the nodules first in a kiln and then an electric arc furnace – a greener alternative to a traditional blast furnace. Even so, the company says its approach will produce 4.9 kilograms of carbon dioxide emissions for every 1 kilogram of valuable metals. Manzoor and his colleagues have found a way to lower these extraction-related emissions. Their system doesn’t involve a kiln. Instead, the nodules would be ground into smaller pellets and placed straight into an arc furnace that also contains hydrogen and argon gas. High-energy electrons flowing from an electrode in the furnace to the pellets would knock electrons off the molecules of hydrogen gas, forming a plasma that can be heated up to temperatures exceeding 1700°C. The hydrogen ions in the plasma then react with the oxygen in the pellets, stripping the oxides away from the alloy and leaving pure metal behind. Besides water, the only by-products are manganese oxide and manganese ligates, which can be used for making batteries and steel. If the hydrogen gas used in the furnace is “green” – meaning it is produced by splitting water with electricity from renewable sources – and the electricity to run the furnace is generated from renewable sources, the process should emit no CO2, according to the researchers. Today, the vast majority of hydrogen is produced using fossil fuels. Metals like manganese are found on land as well as on the seafloor, but at concentrations about 10 times lower. Mining them on land involves moving large amounts of earth, and extracting the metal from the ore often relies on sulphuric acid. The process can result in razed rainforests and polluted rivers. However, land-based mining could be better regulated to prevent environmental destruction, and the smelting of the metals could be done with green hydrogen and renewable electricity rather than fossil fuels, argues Mario Schmidt at Pforzheim University in Germany. At that point, vacuuming up nodules from the seabed wouldn’t necessarily be more sustainable. “We do not see any fundamental advantage for deep-sea mining in terms of carbon footprint,” he says. “The sustainability of deep-sea mining fails because of the threat it poses to the biodiversity of deep-sea flora and fauna.” But the process that Manzoor and his colleagues have developed could help deep-sea mining become more economically viable, according to David Dye at Imperial College London. “In addressing how you would do the extraction metallurgy downstream of actually picking it up off the seabed, you may be able to then open up the business case and the environmental case to make that attractive,” he says. Manzoor stresses that the research isn’t meant to advocate for deep-sea mining, and the environmental impacts should be fully investigated.

Can an International Treaty Save the American Eel?

Overfishing and other threats have depleted populations of this iconic species. A new proposal to restrict international trade under CITES could offer them a lifeline. The post Can an International Treaty Save the American Eel? appeared first on The Revelator.

The sign in front of the van parked just off Route 1 in Lincoln County, Maine, displayed a simple message in big, hand-written letters: “Eels. $2,000/lb.” The man in the van wasn’t selling. He was buying. I pulled my car over, hoping to interview anyone involved in Maine’s lucrative trade in “glass eels” or “elvers” — two of the earliest life stages of the American eel (Anguilla rostrata). The man got out of the van and pulled back his jacket to reveal a holstered gun on his hip. I left without the interview. The gun didn’t surprise me. It was 2012, and Maine media that year carried frequent reports of the danger wrapped up around the eel trade. While catching and selling baby eels remains legal in the state, illegal activity that year ran rampant as eel prices soared. Some people poached the eels rather than follow state harvest regulations. Others tried to burglarize fishermen’s properties to take their catches or rob cash-heavy dealers. Reports of violence were frequent. All for a transparent baby eel, just a couple of inches long.   View this post on Instagram   A post shared by FishGuyPhotos (@fishguyphotos) But little eels are big business. In 2012 in Maine, an estimated 21,611 pounds of glass eels were harvested, valued at over $43 million. (Individual glass eels weigh less than a third of a gram.) The real money isn’t in Maine, though. Once collected, the baby eels are shipped to Asia —  primarily China — where they’re raised in grow ponds until they reach adulthood and full size. After that they’re shipped to Japan, where they’re a culturally important delicacy. Japan’s own eel species, A. japonica, was declared endangered in 2014, a few years after the European eel, A. anguilla, was declared critically endangered. That’s one of the reasons why the market has turned to Maine — one of the few places in the United States where one-common American eels can still be found — as well as Canada and the Caribbean. No one knows how many American eels remain. The IUCN Red List classifies the species as endangered, although attempts to protect them under the U.S. Endangered Species Act have, to date, failed. One thing is certain, though: There aren’t as many as there once were. In 2023 the Atlantic States Marine Fisheries Commission concluded the species was “depleted” from a fisheries perspective, “meaning it is at or near historically low levels due to a combination of historical overfishing, habitat loss, food web alterations, predation, turbine mortality, environmental changes, toxins and contaminants, and disease.” The problems start in the eels’ spawning grounds in the Sargasso Sea and persist throughout their complex life cycles and migrations. That assessment plays a key role this month in attempts to put some controls on the eel trade through the Convention on International Trade in Endangered Species, better known as CITES. A proposal submitted by the European Union would, if passed, place American and Japanese eels (along with all other “lookalike” species)  on CITES Appendix II, which would require any international imports or exports of the species to carry permits showing it was legal, sustainable, and traceable. Japan has historically lobbied against controls on the trade, arguing that it’s important to the country’s culture. But Dr. Susan Lieberman, vice president of international policy for Wildlife Conservation Society, offers a counterargument: Trade restrictions will protect both the eels and their cultural values (for Japan as well as many Native American Tribes and First Nations). “If you don’t protect the eel, you will one day turn around and Japanese people will talk about when they used to eat eel,” she says. A CITES listing won’t “magically solve all the problems for eels,” Lieberman adds. But as with efforts to protect sharks and other species from overconsumption, it could give them more of a chance to recover from their collective pressures. And that’s worked for hundreds of species currently regulated by CITES. “If we didn’t have the treaty, a lot of species would be gone,” Lieberman says. The CITES vote will take place in the next few days. If it passes, trade restrictions would go into effect in June 2027. Either way there’s still a lot we need to do for and learn about the American eel — and the other species in its family — if we hope to protect them. “We need the science to know what level [of trade] is sustainable,” says Lieberman. “We need the science to be supported to assess their populations in the wild. And we need enforcement to make sure that Illegal stuff isn’t leaving the U.S. and Canada and isn’t arriving in Japan and China.” That’s a big set of tasks to help a group of species most people have never seen — let alone studied — in the wild. But embracing eel conservation might pay off. Some researcher suggest American eels’ cultural values, unique natural history, vulnerability to pollutants, and other characteristics could make them good “flagship” species for freshwater conservation. That, in turn, could help motivate people to protect habitat, reduce pollution, restore connectivity (especially by removing dams), and help all manner of aquatic species and the terrestrial species that depend on freshwater systems — including humans. Will this CITES vote be the first step toward that goal? One thing is certain: If we don’t act, we could soon find an eel-shaped hole in cultures around the world and in the American ecosystem.
