Here we present a remarkable scenario in which government-supported incentives have driven the establishment of a commercial fishery targeting a destructive urchin, intentionally encouraging overfishing to protect kelp ecosystems. This ecosystem management strategy is paradoxical in the objective to overfish sustainably. Due to consistent and increasing larval influx, the eradication of urchins in their extended range is implausible. Management, therefore, focuses on maintaining urchin density below a critical threshold while ensuring a viable commercial fishery for long-term species control. Our model dissects the fishery’s impact, offering practical strategies for controlling a destructive range extender given economic and spatial dynamics. Beyond the implications of subsidizing a commercial fishery to counteract the impacts of climate change, our study explores the conflict between exploitation and conservation, challenging traditional views and presenting practical pathways to sustainability. The long-spined sea urchin has colonized areas along the Tasmanian coast owing to climate-induced changes in ocean currents, forming barrens that threaten marine species. This study shows how a government-supported strategy of overfishing this sea urchin could help conservation and fisheries outcomes.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 5","pages":"498-507"},"PeriodicalIF":27.1,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing chemically recyclable plastics is deemed a viable approach to address the ever-growing plastic crisis, but the synthesis of circular polyolefins remains challenging. Here we demonstrate a ring-strain matched concept for the tailored synthesis of circular polyolefins. By designing a well-defined 16-membered unsaturated lactone (Ester-16), a family of chemically recyclable, high-molecular-weight, high-density polyethylene (HDPE)-like materials is produced by the copolymerization of cyclooctene (COE) with Ester-16, followed by exhaustive hydrogenation. These HDPE-like materials have the desirable bulk properties of HDPE. They can be degraded into a well-defined and easily separable macromonomer, specifically AB-like telechelic PE. The molecular weight of the macromonomer can be precisely tailored as required and depends solely on the feed ratio of [COE]/[Ester-16]. The recycled macromonomer can be easily repolymerized into a high-molecular-weight HDPE-like material. This macromonomer–polymer–macromonomer lifecycle rather than monomer–polymer–monomer lifecycle can be repeated with quantitative yields using a facile isolation process. Overall, this work opens opportunities to improve the sustainability of plastics. Developing recyclable circular plastics is a viable approach to reshape the currently unsustainable plastics consumption pattern. Here the authors show a design to obtain recyclable polyolefin plastics with a tailored macromonomer–polymer–tailored macromonomer circular lifecycle.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 4","pages":"422-431"},"PeriodicalIF":27.1,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This contraction results in a secular reduction in atmospheric mass density where most satellites operate in low Earth orbit. Decreasing density reduces drag on debris objects and extends their lifetime in orbit, posing a persistent collision hazard to other satellites and risking the cascading generation of more debris. This work uses projected CO2 emissions from the shared socio-economic pathways to investigate the impact of greenhouse gas emissions on the satellite carrying capacity of low Earth orbit. The instantaneous Kessler capacity is introduced to compute the maximum number and optimal distribution of characteristic satellites that keep debris populations in stable equilibrium. Modelled CO2 emissions scenarios from years 2000–2100 indicate a potential 50–66% reduction in satellite carrying capacity between the altitudes of 200 and 1,000 km. Considering the recent, rapid expansion in the number of satellites in low Earth orbit, understanding environmental variability and its impact on sustainable operations is necessary to prevent over-exploitation of the region. Satellites have become integral to our everyday life, but space debris threatens the sustainability of low Earth orbital space. Greenhouse gases are complicating the problem, leading to longer orbital retention of defunct satellites and increasing the risk of collision.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 4","pages":"363-372"},"PeriodicalIF":27.1,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41893-025-01512-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To be credible, they need robust metrics to assess the practices of producers. We demonstrate an approach for evaluating practice, which is repeatable and explicitly representative of stakeholders. We apply it to nomadic pastoralism in Mongolia, where livestock overgrazing is of concern. Our approach uses judgements from stakeholders about the sustainability of hypothetical but realistic herding scenarios. From these, we create models to predict sustainability scores. These can be applied as tools to assess the actual practices of herders. We use two judgement datasets: one representing producers’ judgements, another a subset that also conforms to the environmental expectations of the certifier. The differences must be negotiated when we choose evaluation methods. The approach could be used for any production system, provided variables are devised that summarize practice and appropriate stakeholders are available to judge the sustainability of different practices. Credible sustainability certifications require robust evaluation to ensure trustworthiness; however, judgements of sustainable practices may differ between the practitioners and the certifiers. Stakeholder engagement can help bridge this gap to provide robust certification evaluation.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 3","pages":"245-255"},"PeriodicalIF":25.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polymeric flame retardants are emerging as a ‘safe’ alternative and so have a high production and consumption volume. However, the environmental fate and toxicity of their derivatives remain unknown, making it difficult to understand and adequately manage the associated risk. We take two tetrabromobisphenol A-based polymers (polyTBBPAs) that are widely used in electronics as model flame-retardant chemicals, and we study their behaviour when they break down in the environment and the toxicity of the derivative products. Our results show that polyTBBPAs break down into smaller products in the environment. Using a non-target screening strategy called BrMiner developed by us, we identified 76 breakdown products of polyTBBPAs with molecular weights in the range 400–2,000 Da. These were detected in environmental samples taken from electronic waste recycling facilities in South China. Toxicity tests with zebrafish embryos showed that when they break down in the environment, polyTBBPAs become more toxic, with mitochondrial dysfunction representing a key toxicity mechanism. This study reveals that there are environmental risks associated with polymeric flame retardants, and therefore, their use should be adequately assessed and regulated. As a ‘safe’ alternative to harmful monomeric halogenated flame retardants, the use of polymeric flame retardants has surged in recent years. The authors show that polymeric flame retardants break down in the environment into small toxic molecules that can pose environmental hazards.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 4","pages":"432-445"},"PeriodicalIF":27.1,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Urbanization not only leads to substantial vegetation loss (direct impact) but also fosters urban vegetation growth (indirect impact). However, the extent to which these direct and indirect impacts affect vegetation dynamics across cities worldwide and how urban greening will change in the future remain unclear. Using satellite-based greenness and impervious surface datasets, we show that positive indirect impacts mitigated 56.85% of the negative direct impacts across 4,718 cities worldwide from 2000 to 2019. Notably, the offsetting coefficient is much greater in Global North cities (79.13%) than in Global South cities (38.01%) partly due to their socioeconomic differences. This disparity in urban greening dynamics will continue in the future. Approximately 60% of Global North cities and 30% of Global South cities will become greener by 2040. Our results reveal the divergent trade-offs between vegetation loss and enhanced vegetation growth in cities of different socioeconomic levels and stages of urbanization. Such insights are crucial for a comprehensive understanding of urban greening dynamics and for devising strategies to attain sustainable development goals. Understanding the urbanization-driven vegetation dynamics is currently limited but would be important knowledge to guide sustainable urban development.

Here we develop a draw spinning/de-acetylation method to prepare cellulose fibres with highly ordered molecular packing that incorporates high strength in the obtained fibres. Specifically, a fibre draw spun from well-dispersed cellulose triacetate solution was de-acetylated to generate cellulose fibres, which were then twisted to spirally align the molecular chains. The resulting fibres exhibited mechanical strength of 3.08 GPa and toughness of 215.1 MJ m−3, much higher than existing fibre materials.
