The Environmental and Human Cost of Making a Pair of Jeans
Americans do love their denim, so much so that the average consumer buys four pairs of jeans a year. In China's Xintang province, a hub for denim, 300 million pairs are made annually. Just as staggering is the brew of toxic chemicals and hundreds of gallons of water it takes to dye and finish one pair of jeans. The resulting environmental damage to rivers, ecosystems and communities in China, Bangladesh and India is the subject of a new documentary called The RiverBlue: Can Fashion Save the Planet?.
It is estimated that 70 percent of Asia's rivers and lakes are contaminated by the 2.5 billion gallons of wastewater produced by that continent's textile industry. In scene after scene in the film, the dark frothy spill off can be seen rushing out of dye facilities while a cadre of scientists and environmental experts detail the public health crisis that has resulted from the largely unregulated manufacturing process.
Co-directed by award-winning documentarians David McIlvride and Roger Williams and produced by Lisa Mazzotta, RiverBlue has won 13 awards globally including Best Documentary at Raindance in London and will be receiving the Green Drop Award from Filmambiente at the World Water council on World Water day, March 22. Three years in the making, the film follows internationally celebrated river conservationist, Mark Angelo, as he paddles the rivers devastated by the chemical waste and the local communities who rely on these rivers for drinking and bathing. These communities suffer from a high incidence of cancers, gastric, skin and related issues afflicting both their residents and factory laborers.

The Chemicals in Your Jeans
What makes the process of making jeans so poisonous to people and planet? Consider just one of the most popular types of jeans today—distressed. To get that "lived in" look, denim is subjected to several chemical-intensive washes. Campaigners from the environmental group Greenpeace, who tested the outflows near dyeing and finishing facilities in the top denim producing towns in Asia, found five heavy metals (cadmium, chromium, mercury, lead and copper) in 17 out of 21 water and sediment samples taken from throughout Xintang one of the locales featured in the project. Toxic campaigners in China also discovered heavy metals like manganese, which can be associated with brain damage, in the rivers.
These chemicals don't stay put. They can also be transported to our North American oceans, atmosphere and food chains and accumulates in places far away from their original source.
Where Should the Change Be?
The question the film poses to viewers: Are brand-name clothing corporations disregarding the environment in their zeal to make their clothes faster and cheaper for the consumer? "Low cost clothing has a high cost attached to it, one to the environment and public health," explains Angelo.
The solution the film's producers unveil is two-fold: through innovation and consumer education there can be change.
Director David McIlvride was determined to find brands making jeans which didn't do damage to the environment. He found the father of distressed jeans: Francois Girbaud who introduced the eponymous stone washed jean decades ago. "It took 40 yrs. before we realized what we made and what we did was wrong," says Girbaud of using permanganate in the 1970s. "If people knew that the spraying of permanganate on your jeans to give you that acid- wash look was killing the guy doing the spraying, would you still want that look? I don't think the customer is aware of what is happening abroad. We have to change the process of making jeans and brands have to be willing to invest because we are destroying the planet," says Girbaud.
A Better Jean Through Technology
In California now, the designer was trying to re-establish himself as manufacturer of good jeans when McIlvride found him. "He led us to the Spanish company, Jeanologia where they distress jeans by engraving images on the fabrics with lasers (light and air) and eliminating water without increasing the cost," says McIlvride. They are now considered a leading industry innovator.

It was a trip to China in the mid 90s that made Alex Penadés and the other execs at Jeanologia want to change the way they did business. At the time the company was a jeans washing consultancy for finishers researching and investigating industry solutions.
"Once we saw the pollution in the rivers and the workers exposed to the chemicals we knew we had to innovate." Jeanologia now creates technology to treat and finish jeans (giving them a certain feel or aesthetic). "We started searching for ways to make garments in a more sustainable way. We have been dyeing clothes with water since the beginning of time and we faced the reality that even though it had been done this way in the mass consumer world, it was not sustainable," explains Penadés.
Jeanologia began working with Girbaud in 2003 and still does. They developed several technologies using light and air to finish jeans using little water and no chemicals. "It wasn't pretty at first and for designers the look is the most important thing," he says referring to their first prototypes back in 1996. "It took us a while to get better to convince industrial finishers to make that shift," says Penadés who works with brands like Levi Strauss, V.F. Corp (makers of Lee and Wrangler)., PVH Corp. (Calvin Klein, Tommy Hilfiger), Inditex (Zara), H&M, Uniqlo and Marks & Spencer among others. Today, laser technology can give a pair of jeans a worn look instead of sandblasting or hand sanding which can be lethal or detrimental to workers and the environment. Their G2 ozone treatments introduced in 2005, fade down the color of a jean instead of using chemicals like bleach or hypochloryte. In 2011, they unveiled eflow technology that uses air (nanobubbles) instead of water to dye jeans and give them properties like softness and wrinkle repelling. The company is also expanding, working on the technology for knits, wool, cottons and blends.
Using these innovations, an average pair of jeans requires just a glass of water to finish when it used to require 300 liters. "It requires a big capital investment," says Penadés of the technology. Depending on the business model the capital investment is made by the dyeing and finishing facilities or brands. "In the beginning it was like preaching in the desert," he says. "Everyone was comfortable doing things in the same way as always. Why should anyone change their methods of production if they are doing well?"
Jeanologia has Environmental Impact software to measure the footprint of every style and brands know where they are and how they can improve. Penadés has seen the tide started to change. Three years ago, about 16 percent of the jeans in the world were made in a sustainable way he says. Now 35 percent of the jeans are made more sustainably. "About 6 billion pairs of jeans are made a year so that means 2 billion pairs are now being made in a more sustainable way."
Innovation Through Science
While filming the movie, most denim manufacturers barred the filmmakers from shooting inside their facilities. Italdenim, one of three denim manufacturers in Italy, invited them to film at their facility. President Luigi Caccia had been making denim for more than 40 years when he too realized rivers were dying and workers were becoming sick from the chemicals they were exposed to. In 2014, he sought to create a cleaner dyeing process. First his company invested in a machine, the only one of its kind in the world, that takes indigo dye and uses electrochemicals (Co2 and O2) and no water to make the colors for their denim.
They then found a company using chitosan, which comes from the waste of the food industry (it is the natural derivative of chitin which is the exoskeleton of shrimp and crab) and applied it to the yarn after dyeing it. "It creates a shell to protect the color so dyes will not rub off and less dye is needed overall to color the denim. This new process saves chemistry, water and energy and is biodegradable. Because there are no chemicals, the process doesn't create skin problems. "Your skin absorbs 65% of what you put on it, good or bad. We introduce chemicals to our skin with the food we eat, the environment we live in and our clothes. You can choose if you want to smoke or not but no one tells you that your denim may be harmful to your body," says Caccia.
The Cost to Make a More Sustainable Jean
Italdenim sells their denim to 30-40 brands around the world including Joe's Jeans and Mother Jeans in the U.S. "It was important to find solutions that did not increase the cost of the fabric so it would be available to all. If a brand wants to buy a sustainable denim it should cost the same as the alternative. We should be able to produce that or we should find ourselves a new job."
Penadés says brands have a choice to manufacture in a traditional way or a sustainable way. "The water and energy of traditional production is costly and so is pollution. Today, including the capital investment, you can produce the same product at the same price. Brands can do it. If the consumer is aware they have to request these kinds of products today. Consumers must also know what their impact on the environment is because of their acts of consumption. It's all about co-responsibility."
Girbaud agrees. He now hears customers asking where things come from and how clothes are made. "Brands are finally talking about this, too. I just hope I live to see the changes."

The conclusion to decades of work to remove a dam on the Middle Fork Nooksack River east of Bellingham, Washington began with a bang yesterday as crews breached the dam with a carefully planned detonation. This explosive denouement is also a beginning.
The History<p>The Middle Fork Nooksack drains glacier-fed headwater streams that run off the icy summit of 10,778-foot Mt. Baker. The Middle Fork joins the North Fork and then the mainstem of the Nooksack River, which travels to Bellingham Bay and Puget Sound. The entire Nooksack watershed stretches 830 square miles across Washington and into British Columbia.</p>
A Plan Comes Together<p>The Middle Fork dam is not a pool dam built for water storage. Much of the time, water flows over the top until dam operators drop a floodgate to divert water to new locations. That water travels about 14 miles through tunnel and pipeline to Mirror Lake, then Anderson Creek, and to Lake Whatcom before finally being delivered to residents' taps.</p><p>Before removing the dam, engineers had to move the water intake 700 feet upstream and situate it at an elevation that still enabled city water withdrawals throughout the year, regardless of flow conditions.</p><p>They also needed to make sure that the rushing water didn't sweep up fish and accidentally send them through the water-supply system.</p><p>"The solution required a fairly complex design in the intake structure, including a fish exit pipe out of that structure to put fish back into the river in a way that meets current environmental permit standards," explains LaCroix.</p>
Project layout for the removal of the Middle Fork Nooksack diversion dam and rebuilding of water intake. City of Bellingham<p>Despite the cost and the work, she says, being able to continue to meet their municipal water obligations while opening up habitat for threatened species has been a win-win.</p><p>"I think there's a lot of benefits to having a dam removal versus fish passage — the main one being that you get a free-flowing river that can be a dynamic ecosystem and change over time," she says. "A static fish ladder just can't provide that same level of ecosystem benefit."</p>
Restoration Success<p>Despite local authorities' championing dam removal on the Middle Fork, the project has largely flown under the radar, overshadowed in the Pacific Northwest by heated discussions about a much larger potential project — removing <a href="https://www.seattletimes.com/seattle-news/feds-reject-removal-of-4-snake-river-dams-in-key-report/" target="_blank">four federal hydroelectric dams on the lower Snake River</a>, a major tributary of the Columbia River.</p><p>Proponents of dam removal there see it as the best chance for recovering threatened salmon populations, including Chinook, which could help starving Southern Resident killer whales. Those dams also provide irrigation water, barge navigation and hydropower, so there's been more pushback against removal efforts.</p><p>Previous dam removals around the country, however, have proved successful at aiding fish recovery and river restoration.</p><p>Most notably the 1999 demolition of <a href="https://therevelator.org/edwards-dam-removal/" target="_blank">Edwards Dam on Maine's Kennebec River</a> restored the annual run of alewives, a type of herring essential to the food web. The fish run has gone from zero to 5 million in the two decades since dam removal. Blueback herring, striped bass, sturgeon and shad have also extended their reach. And the resurgence has brought back osprey, bald eagles and other wildlife, too.</p><p>The overwhelming success of river restoration on the Kennebec helped to spur a nationwide dam removal movement that's now seen 1,200 dams come down since 1999. Last year a record <a href="https://www.americanrivers.org/conservation-resource/a-record-26-states-removed-dams-in-2019/" target="_blank">90 dams</a> were removed in 26 states, including <a href="https://therevelator.org/cleveland-forest-dam-removal/" target="_blank">20 dams in California's Cleveland National Forest</a>.</p>
Spider excavators remove on dam on San Juan Creek in California's Cleveland National Forest. Julie Donnell, USFS<p>The results have been seen in the Pacific Northwest, as well, which boasts the largest dam removal thus far in the country. In 2011 and 2014, the demolition of <a href="https://therevelator.org/elwha-dam-removal/" target="_blank">two dams</a> on Elwha River, which runs through Washington's Olympic National Park, opened up 70 miles of habitat that had been blocked for a century. Scientists have started seeing all five species of salmon native to the river coming back, particularly Chinook and coho. Bull trout, they've observed, have increased in size since the dams were removal.</p>
Benefits on the Middle Fork Nooksack<p>McEwan hopes to see a similar outcome on the Middle Fork.</p><p>Like the Elwha the Middle Fork Nooksack is a relatively pristine river with little development, and dam removal is expected to provide a big boost to fish. The additional miles of spawning habitat are important, but so is the temperature of that water.</p><p>The dam removal will open access to cold upstream waters, which are ideal for salmon and getting harder to come by as climate change warms waters and reduces mountain runoff.</p><p>"This is really great for the climate change resiliency for these species," says McEwan.</p><p>Steelhead will get back 45% of their historic habitat in the river, and scientists expect Chinook populations to increase in abundance by 31%.</p><p>That <em>could</em> help Southern Resident killer whales.</p><p>"When you get to the ocean, it's a little bit of a black box in terms of what you can model and say definitively is going to help, but more fish is better for orcas," McEwan says.</p><p>Upstream habitat will see benefits, too.</p><p>Oceangoing fish like salmon enrich their bodies with carbon and nitrogen while at sea. When they return to their natal rivers to spawn and die, the marine-derived nutrients they carry back upriver become important food and fertilizer for both riverine and terrestrial ecosystems — aiding everything from trees to birds to bears.</p><p>"Once the fish start making their way back, it will start changing the whole ecological system," says Delgado.</p><p><span></span>But any ecological benefit from salmon restoration, either in the ocean or the upper watershed, won't be immediate.<br></p><p>"The population of salmon on the Middle Fork is so low that we expect it's going to take quite a while to rebound," she says. "But the big picture is that what's good for salmon is good for the region — our history and our destiny are intricately intertwined."</p><p>After decades of work, that process of restoration has finally begun.</p>

It can grow to a maximum of six inches (16 centimeters), change color depending on mood and habitat, and, like all seahorses, the White's seahorse male gestates its young. But this tiny snouted fish is under threat.
Building an Ocean Seahorse Destination<p>Seahorses are found in tropical and temperate coastal water worldwide, but are most abundant around Australia, China and the Philippines. </p><p>Trade in the tiny creatures is strictly regulated because of their use in traditional medicine, aquariums and their sale as dried curios. But because they are poor swimmers and cannot easily move elsewhere, habitat loss is a particular threat for these curious animals. </p><p>Seahorses wrap their tails around seagrass and corals to avoid being carried away on currents. They use the habitat to spawn and hide from predators such as crabs, while also feeding on riches of plankton and small crustaceans living in the reef.</p><p><span></span>Where corals aren't available, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/aqc.1217" target="_blank">scientists</a> found seahorses taking up residence in fishing nets and old crab traps abandoned at the bottom of the ocean. </p>
Mixing With the Locals<p>Baby seahorse mortality is high in the wild because they are easily caught, so those bred in the protected environment of the aquarium weren't ready to be released into the wild until early May.</p><p>The team released 90 new arrivals into Sydney Harbor, placing some directly into the purpose-built hotels, and others onto a net that wild seahorses had already settled on.</p><p>Before setting them free, the researchers marked each young seahorse with a fluorescent tag with unique IDs inserted just beneath the skin to track how they get on in the different environments. </p><p>"The most exciting part was being able to put these animals into the wild and then go back a month later and still see them surviving and growing," said McCracken. </p><p>The seahorses will be old enough to mate and reproduce around October or November 2020. And researchers hope that by then, they will be able to breed with the wild population. </p>
Building a Global Seahorse Hotel Chain<p>With seahorses everywhere facing the loss of their coral reef homes, similar projects have sprung up in places like Greece and South Africa, home to the world's most endangered seahorse, the Knysna seahorse. </p><p>"The endangered South African seahorse is benefiting from something quite similar, even though it wasn't intentional," said Peter Teske, professor at the Department of Zoology, University of Johannesburg.</p><p>In the South African <a href="https://www.researchgate.net/publication/322649251_An_endangered_seahorse_selectively_chooses_an_artificial_structure" target="_blank">case</a>, seahorses have bedded down in "Reno mattresses" — wire cages filled with rocks — that were used to build a new marina. Researchers from NGO Knysna Basin Project found the structures acted as a refuge for the animals.<span></span></p><p><span></span>While Teske describes the seahorse hotels as "a positive news story" and a great way to create public awareness of conservation, he added that establishing artificial habitats in some areas will only prevent the extinction of local populations.</p><p>"For a complete recovery, it is necessary to give the natural habitat a chance to regenerate," said the seahorse expert. </p>
Underwater Mascot<p>In Australia, the researchers hope the project could provide an opportunity to raise awareness not only of the plight of the Sydney seahorses but the other animals with which it shares its ocean habitat.</p><p>The waters around Sydney and the east coast are rich in biodiversity and include several threatened species like the weedy seadragon — a relative of the seahorse — and the grey nurse shark. Like the seahorse, they're also under pressure from pollution, ocean traffic and habitat loss through storms and coastal construction. </p><p>"It's a good thing to get people's support and interest. The seahorses are a useful vehicle to get people concerned if the harbor is in trouble," said David Booth, professor of marine ecology at the University of Technology Sydney who is also working on the project. </p><p>The hotels have become an attraction for divers hoping to catch a glimpse of these small but near mythical creatures. </p><p>"Everyone loves seahorses," added Booth, "they are so popular." </p>
