A Spanish court ruling on pollution from industrial pig farming could have far-reaching implications for how animals are kept across Europe.
In the northwestern Spanish region of Galicia, locals have been contending with foul smells, dangerous drinking water and a deteriorating natural environment for years. The alleged culprit: industrial pig farming.
"This used to be a paradise," said local environmental activist Manuel Garcia, standing near a pile of waste from nearby pig and chicken farms. "People here, when they had bad harvests, fed themselves with what nature provided. Hunting, fish, frogs."
But as pig and chicken farms have expanded over the decades, Garcia has seen his home district of A Limia deteriorate. Pigs produce a staggering 2 tons of urine and feces annually. By comparison, an average dog excretes around 270 pounds (122 kilograms) of waste a year.
The waste is rich in nitrates, which can be useful as fertilizer but is harmful in excess. Garcia said nitrate runoff has killed fish and frogs, polluted wells and transformed what he remembers as the lush Lima River into something resembling "a sewage treatment plant."
A farmer by profession, Garcia has spent much of his time in recent years raising awareness of the problem. He said much of the pig waste has been dumped without proper precautions.
But in July 2025, a group of residents, backed by scientists and lawyers, won a case against regional authorities over unchecked livestock pollution that they say harmed the environment and violated their human rights. The first ruling of its kind in Europe, it could set a blueprint for other communities and may even reach the European Court of Human Rights in Strasbourg, where a decision could force change at the national level.
"While the Spanish court granted regional remedies, a Strasbourg ruling could go further by recognizing structural failings," Malgorzata Kwiedacz-Palosz, senior fundamental rights lawyer with ClientEarth, told DW. "[It could require] Spain to implement systemic reforms, including improved nitrate monitoring, farm regulation and water quality protections."

Impacts of nitrogen pollution and the legacy of nitrogen pollution (highly detailed and highly recommended)
Notes:
Most of this post was focused on nitrogen pollution and its effects on aquatic ecosystems and the industries and humans that rely on them. However, nitrogen pollution can take many other forms, and it’s a rather large issue to tackle precisely because of its broad range of effects that range from air pollution and greenhouse gas emissions to soil pollution to water pollution.
In the U.S., most nitrogen pollution that affects aquatic ecosystems is from agriculture and the overuse of fertilizer, and more efficient methods of growing crops are needed to overcome this issue.
However, nitrogen pollution via the air is from burning fossil fuels, which boils down to transportation/driving vehicles, and manufacturing industries.
Edit: someone noted in the comments that nitrogen makes up 78% of our atmosphere and that the pollution is coming from nitrogen compounds like ammonia, nitrates, and nitrous oxides. That is correct and a good clarification to make.

Nitrogen pollution is one of the lesser known yet equally problematic forms of pollution.
In nature, nitrogen is an essential nutrient for life. Plants take in nitrogen from the soil. It is then passed up the food chain and distributed to all organisms.
However, when humans let too much nitrogen escape into the environment, it can have disastrous consequences.
Over applying fertilizer, which is very nitrogen-rich, or improperly disposing of manure (feces and urine from either farm animals or pets) deposits excess nitrogen into the environment.
The excess nitrogen eventually flows into streams, rivers, lakes, and even the ocean via rain or runoff. There it promotes the rapid growth of algae and algal blooms.
However, the algae die quickly too, and as the dead algae decay, they use up all the oxygen in the water. Other aquatic life gets choked out, and a dead zone is created.
Two images of algae blooms: one image shows a body of water covered in a bright green-yellow algae bloom; the bloom covers the whole image and not one spot of clear water can be seen. Two ducks are swimming in the middle of the algae bloom.
The second image shows several dead fish lying belly up in a dark green algae bloom. The images are captioned “Examples of algae blooms”
Nitrogen pollution leads to:
Loss of biodiversity in ecosystems because of creation of dead zones
Money lost decontaminating drinking water
Tourism losses from algae blooms (not a pretty sight)
Fishing industry losses from dead fish and shellfish
Health problems and disease from toxic algae
Another image of an algae bloom follows. The image is a zoomed out picture of an ocean or sea, and over most of the image is a red algae bloom. The image is captioned: “Famous red tides like the annual algae bloom in. the Gulf Coast kill many fish, shellfish, mammals, and seabirds, and make a lot of seafood.. dangerous to eat.”
Other types of nitrogen pollution contribute to:
acid rain. Nitrous oxide from burning fossil fuels mixes with water and increases precipitation acidity
greenhouse gas emissions. Nitrous oxide has 300 times the effect on atmospheric warming as the same amount of CO2.
soil acidification, which can lead to crop failures. Ammonia fertilizers (which contain nitrogen and hydrogen) are the main cause of soil acidification. groundwater and drinking water contamination.
Nitrate, another fertilizer compound, can find its way into groundwater and well water.
How to reduce nitrogen pollution:
If you walk a pet, pick up after them (for the sake of the envi- ronment and your neighbors)
Use public transportation when possible, and increase your car’s fuel efficiency
If you have a yard, DO NOT OVERUSE FERTILIZER!
Most of all, use only the necessary amount of anything. Don’t overuse household or lawn chemicals.
As with reducing carbon emissions, much of the change will have to come from industries, companies, and government legislation.
Lastly, spread the word and educate others! As more people become aware of this issue, greater change can happen.
NASA just released new images focusing on air pollution in the northeastern United States along I-95 from Washington, D.C. to Boston. As you might expect the air quality has improved dramatically. The images show average concentrations of atmospheric nitrogen dioxide (NO2), which primarily comes from human activities such as transportation...
The Keystone State has failed to meet its pollution reduction benchmarks for years, with little response from the EPA.
Excerpt from this Grist story:
In early January, members of the Chesapeake Bay Commission sat in a gray conference room in Annapolis, Maryland, for a routine meeting. The 21-member legislative body, with representatives from Pennsylvania, Virginia, and Maryland, convenes regularly to coordinate interstate efforts to restore and protect the Chesapeake Bay. But as the meeting drew to a close, EPA Chesapeake Bay Program director Dana Aunkst got up and delivered a demoralizing message to the group.
“The TMDL itself is not enforceable,” he said. He was referring to the Total Maximum Daily Load, a set of science-based limits for three pollutants — nitrogen, phosphorous, and sediment — flowing into the bay. The states in the Chesapeake Bay Watershed have agreed to achieve the TMDL by 2025, and the EPA committed to enforcing it under the terms of a 2010 settlement. But Aunkst went on to describe the TMDL as merely “an informational document” that was “aspirational.”
Aunkst’s comments were jarring to some in the room, but they weren’t entirely out of left field. Pennsylvania, by far the largest source of pollution entering the Chesapeake Bay Watershed, has failed to meet its pollution reduction benchmarks for years, with little response from the EPA. This single state’s negligence threatens the success of the entire regional program.
The Chesapeake is the largest estuary in the United States, a nationally significant economic resource, and a crucial habitat for thousands of species. But the influx of pollution from upstream sources has led to fishery declines, recurring “dead zones” where pollutants starve aquatic animals of oxygen, and regular algae blooms that suffocate underwater plant life. Even after nearly 10 years of strategic planning and implementation of these pollution reduction plans by neighboring states, its overall health is still poor.
And Pennsylvania seems increasingly to blame. In August of last year, the state’s Department of Environmental Protection released its third and final Watershed Implementation Plan, or WIP. The plan admitted that PA was only about 30 percent closer to achieving its target for nitrogen pollution than it had been in the 1980s. Not only was the Keystone State entering the final phase of the cleanup far behind where it should have been, but the state’s plan for phase three still had it falling 25 percent short of the 2025 target. That underwhelming plan also had a funding deficit of about $324 million per year. In December, the EPA signed off on the plan with no indication of imposing consequences.
Authorities have closed two official swimming sites in the Netherlands and issued dozens of health warnings as summer temperatures draw more
Authorities have closed two official swimming sites in the Netherlands and issued dozens of health warnings as summer temperatures draw more people to natural waters, NOS reports. A swimming ban has been imposed at De Betteld holiday park in Zelhem, Gelderland, where tests revealed “extremely high levels” of PFAS. At It Nannewiid near Oudehaske in Friesland, swimming has been declared unsafe because of nearby construction work.
Across the country, forty sites have tested positive for blue-green algae, also known as cyanobacteria, which can cause nausea, diarrhea and skin irritation. Swimmers can also develop swimmer’s itch, a rash triggered by parasites present in the water.
While swimming is not automatically forbidden at locations where blue-green algae are detected, experts strongly recommend caution. “Use common sense,” officials advise. Swimmers are urged to check the water’s appearance before entering. A visible scum layer or an intense green color should be treated as a clear warning to stay out.

Judges have ordered the Dutch state to take action to reduce nitrogen-based pollution in the country’s most vulnerable habitats or face a fine of €10 million in 2030.
This year’s targets do not have to be met but the aim to reach a 50% reduction in five years time must be a reality, the court said, adding that the state had been negligent in not making reducing nitrogen-based pollution a priority.
The case was brought by Greenpeace, which argues the Netherlands is not doing enough to protect the natural environment from the impact of excessive nitrogen.
The case is a “last chance to save the most vulnerable habitats because if nitrogen emissions don’t go down, we risk losing unique plants and animals,” Greenpeace said at the court hearing last November.
The campaign group wants to force the government to cut nitrogen emissions drastically and the courts to check the government’s approach to dealing with the problem against the European bird and habitat directives.

I've no doubt the government will have the ruling overturned in a higher court, much like Shell did after it was told to slash its carbon footprint.

Cabinet sources have told broadcaster NOS that the current programme to tackle nitrogen-based pollution is being torn up, and that the 12 Dutch provinces can call a halt on their efforts to comply.
The plan, known by the acronym NPLG, passed responsibility for tackling excess nitrogen to the provinces, which would all draw up their own programmes to meet environmental targets. If one province managed to improve, that would allow it to issue new permits for housing, for example.
The provinces have been working on the plans for two years and have called for the policy to continue, with more cash.
But new farm minister Femke Wiersma, who represents the farmers’ party BBB, is highly critical of the current strategy and the new government has scrapped the €20 billion budget for the programme.

So the provinces, largely controlled by the BBB, wanted the program to continue, but the BBB agriculture minister, cancelled it. The BBB has a total of 7/150 seats in parliament. Makes perfect sense.
