EU: Human rights-centred Digital Services Act must include global voices

Ivan Marc/Shutterstock

ARTICLE 19 joined partner organisations in the Digital Services Act Human Rights Alliance (DSA HR Alliance) in signing an open letter calling on the European Union regulators to adopt a human rights-based approach when implementing and enforcing the DSA and to include insights from international civil society groups in non-EU countries.  

DSA Human Rights Alliance

The Digital Services Act Human Rights Alliance is a group of human rights organisations representing diverse communities across the globe. The Alliance came together around the central tenet that the Digital Services Act must adopt a human rights-based approach to platform governance and that EU policy makers should consider the global impacts of EU legislation. Many members of the Alliance know firsthand why this is necessary. As grassroots organisations operating in non-EU countries, they have monitored human rights abuses stemming from shortsighted legislation tailored to prosecute human rights defenders and to suppress dissent.

DSA negotiations and recommendations

During the DSA negotiations, the DSA HR Alliance issued a number of recommendations for EU policymakers to make sure that future EU internet rules follow a human rights-based approach to content governance and platform accountability. Among others, we supported the following recommendations:

  • to preserve the conditional model of intermediary liability for user-generated content hosted by online platforms;
  • to avoid disproportionate demands on smaller service providers that would put users’ access to information in jeopardy;
  • to reject unduly short time frames for platforms to remove problematic content due to their detrimental impact on the right to freedom of expression online and other fundamental rights;
  • to not mandate the use of intrusive automated content moderation and content curation tools on platforms, but to focus on safeguarding people’s fundamental rights;
  • to protect user privacy and personal data protection rights when it comes to cooperating with law enforcement authorities and to refrain from awarding such authorities the status of trusted flaggers;
  • to strengthen due diligence obligations of large platforms, with specific focus on mandatory ex ante fundamental rights impact assessments and to make sure that risk assessment and mitigation measures respect necessity and proportionality requirements.

Human rights-centred enforcement

We welcome the fact that many of our suggestions were taken into account by the drafters of the final DSA text. However, the DSA still features problematic aspects that can have negative consequences for vulnerable and historically oppressed groups. There is ambiguity in the text of several provisions, and the practical consequences they may have once implemented are unknown. For example, as the DSA gives considerable power to government agencies and other actors with partisan interests to flag and remove potentially illegal content, these actors may take advantage of the vagueness of the concept to undermine fundamental rights protection. Moreover, it is not clear how very large online platforms will mitigate risks in practice. The role of civil society groups, researchers, and overall stakeholder engagement in the due diligence process is still shrouded in mystery.

The co-regulatory model of the DSA is an opportunity to ensure that civil society organisations and digital rights defenders worldwide have a voice in, and are allowed to make a difference, during the implementation and enforcement of the Act. However, if implemented incorrectly, it could also invite shadow negotiations suspected of corporate capture, and to exclude fundamental rights voices. Such worrisome developments will ultimately deepen the existing adverse fundamental rights impacts of the platforms’ practices and policies, particularly on vulnerable communities. Thus, for the DSA to constitute a positive framework aimed at protecting digital rights also beyond the EU, there must be human rights-centred implementation and enforcement of the text over the next few years, accompanied with proactive and meaningful engagement of international civil society voices. The DSA HR Alliance has a critical role to play in this process.

We are already witnessing the spread of platform regulatory bills in regions outside the EU, many of which are inspired by or directly copy the principles of the DSA. We also have started assessing the undeniable impact that the DSA has throughout the Global Majority.

Call on EU regulators to value insights of non-EU voices

The DSA HR Alliance calls on EU regulators to establish transparent international regulatory dialogues, and for an inclusive implementation and enforcement approach that includes meaningful and formalised stakeholder engagement.

We urge them to value the insights that non-EU organisations can bring to the implementation process of the DSA. This is the case especially for grassroots organisations operating in the Global Majority and civil rights groups fighting for the protections of historically oppressed and vulnerable groups. These groups frequently find themselves on the receiving end of badly designed legislation and can contribute substantially to minimising the damage throughout the platforms’ value chains.

The good advice that could lift people out of poverty

Peer-Reviewed Publication

UNIVERSITY OF EAST ANGLIA

Providing access to housing, debt, and benefit advice within food banks could help lift people out of poverty - according to a University of East Anglia study.

Researchers worked with Norwich Foodbank centres, part of the Trussell Trust, on a pilot project that saw representatives from Citizens Advice and Shelter posted within the service.

The ‘Making a Difference’ initiative meant that people forced to use a food bank were also able to access advice on a range of issues - from housing and debt to benefits.

It is now hoped that this scheme will be rolled out to foodbanks nationally.

Lead researcher Dr Sarah Hanson, from UEA’s School of Health Sciences, said: “As the cost-of-living crisis continues, more and more people are turning to food banks because they simply can’t afford to eat.

“This might be because they have had an acute change in circumstances, are on a low income, in debt, or because their benefits have either changed or been delayed.

“We wanted to see whether making more support available to people at food banks would help - so that they would no longer need to rely on emergency food.

“We know that signposting, for example giving information about other local organisations, is not enough. This is because people’s issues are complex and need a more holistic approach.”

The Norwich Foodbank has supported 11,797 people in the last year. This has shot up from 8,905 people in 2015.

The ‘Making a Difference’ project is a pilot advisory scheme in the region with staff from Shelter and Citizen’s Advice posted within some of its food banks.

The UEA team interviewed food bank volunteers and advice workers, to provide lived experience feedback on the scheme.

Dr Hanson said: “One of the main things that emerged was that having a person-centred, holistic, and compassionate approach is essential for clients with complex needs that cut across many different services.

“It can be very difficult for people to navigate the benefit system, the housing system, social services – you need a joined-up approach with advisers that can help on a number of levels.

“A lot of people are missing out on benefits such as Healthy Start vouchers and pension credit - because they don’t realise that they are entitled to them.

“Many people visiting food banks have poor mental or physical health, as well as personal trauma. Having advisers available at the point of need means that people don’t have to tell their stories multiple times to different organisations.

“We found that the service is reaching very vulnerable people who fall through the gaps, in the heart of really deprived communities. These people may have previously found advice services inaccessible, and they are too often socially excluded from opportunities and services that could support them.

“Importantly, the initiative is empowering clients by treating them with dignity and sensitivity in often distressing circumstances,” she added.

But while the scheme is helping food bank clients, the researchers found that frontline staff may need some help themselves.

Dr Hanson said: “We heard that being on the frontline can impact mental health. It is therefore important that anyone who is listening to and supporting people in crisis in a very challenging landscape, should have access to support themselves.”

Rhiannon Barrow​, Trussell Trust financial inclusion manager for the East of England, said: “The partnership between UEA and Norwich Foodbank was one of the first collaborations between a university and a Trussell Trust Foodbank.

“The evaluation of the ‘Making a Difference’ project demonstrates the effectiveness of working in partnership with organisations so individuals are supported holistically and don’t have to be retraumatised by repeating their stories.

“The evaluation also enabled reflection and a space to discuss continuous improvement to enable Norwich Foodbank to better serve their community and support staff and volunteers, which they always strive to do.”

Hannah Worsley, Norwich Foodbank project manager, said: “We were delighted to work with the UEA research team to independently evaluate and understand our project, in terms of what we expected the outcomes to be and what some actual outcomes were.

“The interviews with our volunteers, and Citizen's Advice and Shelter advisors’ insights, along with the research provided by UEA, gave us a thorough and better understanding of what this work is currently achieving for those we serve and, most importantly, how we can improve the service for our clients.”

Nidhi Mittal, pathfinder lead at the Trussell Trust, said: “The UEA study, funded via the Trussell Trust Pathfinder programme, is an innovative piece of work that provides valuable insights into the impact that financial inclusion services embedded within a holistic model of support can have on reducing the need for emergency food parcels.

“The Pathfinder programme at Trussell Trust aims to support innovation and learning on how we can address underlying causes of poverty in the UK, and this study led by UEA offers some excellent testimony for the work of Norwich foodbank and a base of valuable learning and knowledge for our wider foodbank network and partners.”

Birmingham start-up awarded funding for technology that generates water out of air


Grant and Award Announcement

UNIVERSITY OF BIRMINGHAM



NovNat Tech Ltd, a visionary new company based in the Unit 9 incubator at the Birmingham Research Park, has secured funding from Innovate UK to develop a novel technology that can generate water out of air. 

NovNat Tech is offering solutions to one of the most critical problems of today and the future, the global water scarcity crisis, and is developing a first of its kind ‘atmospheric water harvester’ to help address the global water shortage. 

The harvest uses a proprietary material that has already been vigorously tested for its water sorption characteristics, and has displayed breakthrough performance, capturing and releasing water from air at a faster rate and with less energy required than any existing material.

The Innovate UK funding will support the development of an on-board vehicle atmospheric water generator, that can produce clean water while on the go, and the five-month project will allow the company to further expand on the core technologies and IP developed so far.

Founders Abdulbari Belouafi and Ibrahim Albaik first met as graduate researchers at the University of Birmingham, after which they worked on developing the breakthrough technology, which has broad-based patent protection. 

They then attended UoB Elevate, an incubator and business growth programme for University of Birmingham students and graduates, before founding NovNat Tech, an engineering design company to develop water harvesting systems enabled by advanced materials.

While the innovators saw a broad range of applications for their technology, the University’s Entrepreneur in Residence helped them focus their thinking and shaped their business proposition.  

The innovators applied for, and won, grant funding from the Climate Innovation Platform, and entered Unit 9 to build a prototype that can collect water from air, utilizing the waste heat emitted from various processes within buildings to produce potable water, with a net zero carbon footprint.

Abdulbari said: “As first-time innovators we were unaware of the range of support that is available.  The monthly tenant meetings allow us to discuss our current challenges with fellow innovators and business support advisors from University of Birmingham Enterprise, and the information share and signposting is truly valuable.”

Unit 9, University of Birmingham Enterprise’s incubator, provides flexible, low-cost facilities to meet the needs of aspiring companies who want space for medical research, proof-of-concept, or prototyping activities.  For information about space or facilities, contact Angie Reynolds, Head of Birmingham Research Park

Belief in animal​​s’ capacity for emotion linked to better health and welfare


New research finds equids whose owners believe animals feel emotions or who have an emotional bond with them were in significantly better health

Peer-Reviewed Publication

UNIVERSITY OF PORTSMOUTH



Working equids whose owners believe in their capacity to feel emotion have significantly better health and welfare outcomes than those whose owners do not, according to new research by the University of Portsmouth and international animal welfare charity, The Donkey Sanctuary. 

The study is the first to show a link between the welfare of working equids - including donkeys, horses, and mules - and the attitudes and beliefs of their owners, in different countries and contexts around the world.  

Researchers visited equid-owning communities in Egypt, Mexico, Pakistan, Senegal, Spain and Portugal, where they carried out ​​​​welfare assessments. This included a questionnaire for owners about their beliefs, values and attitudes toward their ​animals​; and a ​detailed assessment​ of the equids’ ​welfare. 

The study, published in the Journal of Applied Animal Welfare Science, found animals whose owners believed they felt emotions or who had an emotional bond with them, were in significantly better health and had higher body condition scores than those whose owners did not​,​ or who focused on ​how profitable or useful they were​.

Similarly, animals whose owners believed they could feel pain were much less likely to be lame. These relationships were evident ​across multiple​ countries​, with varying economic incomes.​     ​​​     ​ 

Lead author, Dr Emily Haddy, Postdoctoral Research Fellow at the University of Portsmouth’s ​Centre for Comparative and Evolutionary Psychology​, said: “We know people’s feelings toward their animals can impact their welfare, but we wanted to know if this differs across cultures. Our research involved equid-owning communities in six countries, whose animals worked in a diverse range of contexts including agriculture, tourism and construction. 

“​This​​ ​is the first study to link owner attitudes to the welfare of their working equids across multiple countries and contexts. Our findings highlight the importance of the relationship between owners and their animals, and its significant impact on animal health and welfare.” 

Co-author and Executive Director of Equine Operations at The Donkey Sanctuary, ​​​Dr ​Faith Burden, said: “We have long understood that donkeys and mules are sensitive and sentient beings, who fare best when they are treated​ as individuals and​ with the kindness and respect they deserve. This study provides further peer-reviewed, scientific evidence​ to support our work across the world​.  

“What’s really exciting is these findings could inform and increase the efficacy of future welfare initiatives. For example, promoting emotional connection and awareness of animal sentience among owners of working equids could potentially influence attitudes and lead to improvements in the welfare of working equids around the world.” 

Co-author, ​Dr Leanne Proops​, Associate Professor in Animal Behaviour at the​ University of Portsmouth’s Department of Psychology​, ​added​​​: “This is a fascinating study that highlights the link between attitudes to animal sentience and welfare. However, it’s important to avoid assumptions about the owners of animals who had poorer health and welfare indicators. 

​​“​It’s possible these owners simply don’t have the resources to look after their animals as well, and because they don’t like to think of them suffering, they adjust their beliefs to think that their animals don’t feel pain. This is a well-documented psychological technique that people use to minimise psychological distress when their behaviour and beliefs don’t align. 

“This is a very important study that paves the way for further research to establish causality, and a greater understanding of compassion and animal welfare.” 

Understanding the intersection of Alzheimer’s Disease caregiving and the LGBT experience


Insight into disparities can help meet needs of LGBT people with dementia and their caregivers

Peer-Reviewed Publication

REGENSTRIEF INSTITUTE




INDIANAPOLIS – A new study of caregivers of LGBT older adults living with Alzheimer’s disease provides rare insight into the intersection of caregiving and the LGBT experience. 

Researchers from Regenstrief Institute and the medical schools of Indiana University and University of Colorado report that many common caregiver experiences -- such as feelings of social isolation and of being overwhelmed -- are similar for caregivers, whether an individual with Alzheimer’s disease is LGBT or not. However, because LGBT older adults often do not have adult children who can serve as caregivers or may be estranged from their families of origin, provision of the care they need, frequently provided by spouses or partners, is especially challenging.

Health disparities experienced by LGBT individuals have been well documented. Risk factors -- such as higher rates of smoking and alcohol consumption in the LGBT population -- often lead to poor health outcomes and increase the likelihood of Alzheimer’s disease in older LGBT adults and amplify the challenges faced by their caregivers. 

“We wanted to explore how health disparities affect LGBT persons with dementia and their caregivers. It is not surprising that many of the experiences of caregivers of LGBT older adults with Alzheimer’s disease are very similar to those of any caregiver. But we found that in many cases those providing care for LGBT individuals with dementia felt they had to come up with their own solutions to challenges because the ones that have been created were not inclusive in some way,” said study senior author Alexia Torke, M.D., M.S., of Regenstrief Institute and Indiana University School of Medicine. “We found that caretakers of LGBT older adults often wrestled with whether or not support groups would be supportive and they had mixed experiences. One caregiver reported not knowing where to go to find a lesbian support group, while another joined a general support group in her partner's assisted living community and found it to be very welcoming.”

“Our phenomenological study of the experiences of caregivers for LGBT older adults with AD found themes similar to the concerns of all caregivers, including the importance of social support, financial security and grief and bereavement support. But it also showed that LGBT status could affect the experience of healthcare in various ways, including raising concerns about discrimination and acceptance in care settings,” said study lead author Carey Candrian, PhD, of the University of Colorado School of Medicine. “The importance of doing qualitative research is that we acquired a lot of depth in terms of the information discovered. The LGBT caregiving experience is something where there isn't a lot of research, and this qualitative work can help us determine the most important questions we need to be asking.”

"Caregivers of LGBT individuals with Alzheimer’s disease may feel that they're shouldering a heavier burden by themselves given a limited support network due to not having children and lack of family of origin support,” said Dr. Torke. “And there's another dimension to this, for future study, which is that issues that all caregivers experience might actually be more challenging for LGBT caregivers. For example, until recently, marriage was not a possibility, and some of the couples did not necessarily get married, which might affect insurance benefits and caregiver access.” 

The 19 caregivers participating in the study ranged in age from 44 to 77 years old; 74 percent were lesbian, 16 percent were gay, 5 percent were straight, and 5 percent were unknown. They were from California, Colorado, Georgia, Maryland, Connecticut, New Mexico, Minnesota and Missouri, providing a demographically diverse perspective.

Slightly more than half of the caregivers were spouses of the person with dementia and a quarter were identified as a spouse equivalent or unmarried partner. Approximately two-thirds of the caregivers had been in a relationship for 15 years or more with the person living with dementia.

Conducting and analyzing in-depth interviews with these caregivers, the researchers identified five themes:

  • Caregiver tension and isolation,
  • Financial stress and security, 
  • Lack of social support and connection,
  • Engineering grief support,
  • Entrapment of past and present stigma and discrimination

One of the most interesting findings of the study was that the LGBT experience is very diverse, with some individuals feeling they had a close, tight knit social circle that was incredibly supportive and others feeling like their LGBT status made their social circle smaller and their stress much, much higher,” said Dr. Torke. “It's important to recognize that being LGBT can affect people in diverse ways, but in some ways can be thought of as a strength where a person might have close friendships or what people often refer to as a chosen family if they have bad relationships with their family of origin.”

Noting that LGBT individuals become caregivers at a higher rate than the general population, the authors write: “Discrimination related to LGBT status was an important theme over the participants’ lives and occurred for several during dementia care. While other themes were similar to prior AD studies, LGBT status affected these other aspects of the caregiving experience. Findings can inform future programs that better meet needs of LGBT people and those who care for them.”

Decoding the secrets of human health: scientists worldwide collaborate on developing a holographic digital mannequin


Peer-Reviewed Publication

ENGINEERING




A groundbreaking research project aimed at revolutionizing the field of life sciences and providing unprecedented insights into the human body had been announced. The significant research program, titled "digital life and holographic human body" brought together leading scientists, researchers, and experts from all around the world to develop a pioneering digital model that represents the physiological and pathological processes of human life system activities in real time.

 

The concept of a “holographic digital mannequin” involves reconstructing the micro-, meso-, and macro-networked dynamic life information dataset of the human body using advanced technologies such as digital twin and computer simulation. By categorizing, integrating, and digitizing existing theoretical models, the research aims to decode the complex life activity processes and uncover the exact causes of accurate and effective intervention and rehabilitation measures for improved initiative for this research program, which was ignited during the 696th Xiangshan Science Conference on the theme of Revealing Three Major Scientific Problems in the Field of Life and Analyzing the Mechanism of Human Information and Energy Network.” Organized by Academician Cong Bin, the conference attendees unanimously agreed to spearhead this significant effort in developing the field of “digital life and holographic human body.”

 

The global implications of this research project span multiple disciplines, including life sciences, medicine, and information technology. It aims to establish an international hub for cutting-edge scientific research and technological advancements while attracting exceptional talent from around the world. Cooperation among scientists worldwide are crucial to establish a unified framework and research and development standards.

 

The creation of a holographic digital mannequin represents a remarkable convergence of medicine, life science, information science, chemistry, physics, and mathematics for collaborative innovation and development. Drawing inspiration from the ontological and holistic theories of traditional Chinese medicine (TCM), this major research undertaking seeks to analyze the evolution of living matter in the body’s four-dimensional spatial operation law. The project will construct a cross-fusion platform, incorporating information science, brain science, physics, modern medicine, life science, and TCM to bring the holographic digital mannequin to life.

 

The ultimate goal of this ambitious endeavor is to decipher the code of human life and health by unraveling the mutual regulation mechanisms among multiple life systems. As this code is decoded, it will drive further scientific and technological progress and open up new opportunities for comprehensive development across various fields. The layered decryption of the human holographic life system promises to inspire fresh perspectives and advancements, paving way for the future of science and technology.

Plastic pollution on coral reefs increases with depth and mostly comes from fishing activities, Nature study finds


In the most comprehensive survey of plastic pollution on coral reefs to date, researchers find troubling signs of human impact and promising strategies to ramp up protections

SAN FRANCISCO, CA (July 12, 2023) — In a paper published today in Nature, researchers from the California Academy of Sciences, University of São Paulo, University of Oxford, University of Exeter, and other collaborators reveal the extent of plastic pollution on coral reefs, finding that debris increases with depth, largely stems from fishing activities, and is correlated with proximity to marine protected areas. 

Through underwater visual surveys spanning more than two dozen locations across the Indian, Pacific, and Atlantic oceans, the researchers expose the abundance, distribution, and drivers of plastic pollution at various depths, which in turn enables them to identify what conservation efforts could be prioritized—and where—to protect our planet’s vulnerable coral reefs.

“Plastic pollution is one of the most pressing problems plaguing ocean ecosystems, and coral reefs are no exception,” says Hudson Pinheiro, PhD, the study’s lead author, a biologist at the Center for Marine Biology of the University of São Paulo, and an Academy research fellow. “From macroplastics that spread coral diseases to fishing lines that entangle and damage the structural complexity of the reef, decreasing both fish abundance and diversity, pollution negatively impacts the entire coral reef ecosystem.”

Surveying reefs from shallow to never-before-seen
For the study, the researchers conducted more than 1,200 visual surveys across 84 shallow and mesophotic reef ecosystems located in 14 countries. To survey hard-to-reach mesophotic—or ‘twilight zone’—coral reefs that exist between 100 and 500 feet (30 and 150 meters) deep, researchers relied on specialized diving gear that few other scientific dive teams are trained to safely use.

According to the study, coral reefs appear to be more contaminated by plastics and other human-derived debris than other marine ecosystems that have been evaluated, but are much less polluted than shoreline ecosystems like beaches and wetlands. 

However, contrary to studies of near-shore environments, the researchers found that the amount of plastic increased with depth—peaking in the mesophotic zone—and was mostly derived from fishing activities. 

“It was surprising to find that debris increased with depth since deeper reefs in general are farther from sources of plastic pollution,” says Luiz Rocha, PhD, Academy curator of ichthyology and co-director of the Academy’s Hope for Reefs initiative, who was the senior author on the study. “We are almost always the first humans to set eyes on these deeper reefs, and yet we see human-produced trash on every dive. It really puts the effect we have had on the planet into perspective.”

Of the total debris, 88% was macroplastics larger than about two inches (five centimeters). The researchers posit that the potential causes of pollution reaching such depths include increased wave action and turbulence near the surface dislodging trash and carrying it away, recreational divers removing debris from more accessible shallow reefs, and shallow corals with higher growth rates overgrowing the trash hiding it from their surveys.

The lowest and highest densities of pollution
Over the course of the study, the researchers found human-derived debris in nearly all locations, including some of the planet’s most remote and pristine coral reefs, such as those adjacent to uninhabited islands in the central Pacific. The lowest densities of pollution—around 580 items per square kilometer—were observed in locations such as the Marshall Islands. Comoros, an island chain off the southeast coast of Africa, had the highest density of pollution with nearly 84,500 items per square kilometer—the equivalent of around 520 pieces of debris on one football field.

Troublingly, the researchers say that because these plastic-laden deeper reefs are more difficult to study, they are rarely included in conservation efforts, management targets, and discussions despite harboring unique biodiversity that’s often not found on shallow reefs

“Our findings provide more evidence that the mesophotic is not a refuge for shallow reef species in a changing climate as we once thought,” says co-author Bart Shepherd, director of the Academy’s Steinhart Aquarium and co-director of Hope for Reefs. “These reefs face many of the same pressures from human society as shallow reefs, and have a unique and poorly-studied fauna. We need to protect deeper reefs and make sure that they are included in the conservation conversation.”

Fishing gear foremost source of pollution
Although the researchers found much consumer debris, such as water bottles and food wrappers, which are often the main source of plastic pollution in other ecosystems, nearly three-quarters of all plastic items documented on the surveyed reefs were related to fishing like ropes, nets, and fishing lines.

“Fishing gear, which even as debris continues to catch marine life through what we call ghost fishing, appears to contribute a large proportion of the plastic seen on mesophotic reefs,” says co-author Lucy Woodall, PhD, principal scientist of Nekton and associate professor in marine conservation biology and policy at University of Exeter. “Unfortunately, fishing gear debris is often not reduced by general waste management interventions; therefore specific solutions related to the needs of fishers should be considered, such as no-charge disposing of damaged gear in ports or individually labelling gear to ensure fishers take responsibility for misplaced equipment.”

To uncover the drivers of coral reef pollution, the researchers analyzed how the abundance of human-derived debris correlated with a number of geographic and socioeconomic factors. In general, they found pollution on reefs increases with depth and proximity to densely populated cities, local markets, and, counterintuitively, marine protected areas. Since most marine protected areas allow some fishing within or near their borders and are typically more productive than other locations due to their protected status, they are often heavily frequented by fishers, according to the researchers.

“Our findings reveal some of the complex collective challenges we face when dealing with plastic pollution,” Pinheiro says. “As marine resources around the world dwindle, humans that rely on those resources are turning to deeper habitats and those closer to marine protected areas where fish remain abundant.”

Science-based solutions to fight reef pollution
Ultimately, the researchers hope that by teasing out the major drivers of pollution, as well as demonstrating that plastic pollution increases with depth, conservation efforts can be redirected to better protect and ensure a thriving future for Earth’s coral reefs.

“The results of our global study shine a light on one of the many threats that deep reefs face today,” says study author and University of Oxford marine biologist Paris Stefanoudis. “Because these ecosystems are ecologically and biologically unique, much like their shallow-water cousins, they need to be conserved and explicitly considered in management plans.” 

In particular, they stress the need to expand the depth of marine protected areas to include mesophotic reefs, update international agreements on combating plastic pollution at their source—such as those discussed at the recent Intergovernmental Negotiating Committee on Plastic Pollution—to include fishing gear, and develop low-cost biodegradable alternatives to fishing gear that will not adversely impact the well-being of coastal communities that rely on sustainable fishing for their livelihoods. 

“Despite the disturbing overall trend, there were some places where we found relatively little debris, which shows us that there are effective strategies for preventing plastic pollution,” Shepherd says. “If we act fast and employ science-based solutions, there absolutely is hope for coral reefs.”
