Sustainable and Safe Recycling: Protecting Workers Who Protect The Planet

A new study by environmental, occupational safety, and community benefits experts in collaboration with researchers at the University of Illinois School of Public Health, finds that recycling work is unnecessarily hazardous to workers' health and safety. Seventeen American recycling workers died on the job from 2011 to 2013. Recycling workers are more than twice as likely to be injured at work as the average worker.By ensuring health and safety compliance across the industry, the study's authors say cities can create good and safe recycling jobs, and they offer concrete policy recommendations for cities.Key findings from the report include:The industry's high injury and fatality rates are a result of unsafe working conditions around heavy machinery and exposure to hazardous items on the sort line, like hypodermic needles, toxic chemicals, and animal carcasses.Many waste and recycling companies rely heavily on temporary workers, who have fewer workplace protections and are less likely to be informed of their legal right to a safe and healthy workplace

Unravelling migratory connectivity in marine turtles using multiple methods

On the front line: integrated habitat mapping for olive ridley sea turtles in the southeast Atlantic

notes:types: JOURThis study demonstrates that it is imperative that marine conservation policy recognizes the spatial extent of highly migratory species with expansive ranges. It also highlights that deficiencies exist in current knowledge of bycatch, both in gear specificity and in catch per unit effort. With integration of vessel monitoring system (VMS) data and those on fisheries catch, knowledge and understanding of bycatch may be improved, and this will ultimately facilitate development of appropriate management strategies and long-term sustainability of fisheries and their supporting ecosystems

A qualitative exploration of self-kindness and 'treating oneself'' in contexts of eating, weight regulation and other health behaviours: Implications for mindfulness-based eating programmes

Background: Caring for oneself through mindfulness and compassion to improve or enhance health behaviors, and specifically eating behaviors has come to the forefront of scientific inquiry. The experiences and challenges for people in decision making around food within the context of self-kindness for body and mind care have not been previously explored.Aims: This study explored the experiences of eating behaviors in a community sample and examined the understanding of self-kindness and its relationship to eating behaviors and wellbeing of body and mind.Methods: A phenomenological theoretical position was taken; data were collected using individual semi-structured interviews. The sample was twenty-five members of the wider community in the West Midlands in England. The data were analyzed using Braun and Clarke’s (2006) procedural steps for thematic analysis.Results: Two overarching themes were inductively formulated: ‘Thinking about eating’ and ‘Caring for body and mind’. Five themes were constructed: (a) Treat food is exceptional eating, (b) The proof of the pudding is in the planning, (c) Dieting is a dirty word, which are subsumed under Thinking about eating, and (d) Self-kindness is a disavowed abstract noun, and (e) Self-kindness: A rose by any other name; under Caring for body and mind. Participants described a number of ways of treating themselves both with food and with other activities and pleasure in eating was discussed in terms of social aspects of eating rather than food. Two clear contradictions within narratives around eating and health behaviors were shown. Participants largely eschewed the concept of dieting, but described engaging in highly regulated and restrained eating. There was a lack of connection with the notion of self-kindness; although positive eating and exercise health behaviors were undertaken, they were described as necessary self-regulation, not construed as acts of self-kindness.Conclusion: The results suggests a lack of ease in the interpretation of being kind to oneself as a means of improving mental wellbeing, and an inability to relate self-kindness to physical health behaviors. The association of self-kindness with self-indulgence, and the described disconnect between hunger, satiety and pleasure in eating has implications for interpretation of mindful eating scales, practices and interventions

Pan-Atlantic analysis of the overlap of a highly migratory species, the leatherback turtle, with pelagic longline fisheries

This is the final version of the article. Available from the publisher via the DOI in this record.Large oceanic migrants play important roles in ecosystems, yet many species are of conservation concern as a result of anthropogenic threats, of which incidental capture by fisheries is frequently identified. The last large populations of the leatherback turtle, Dermochelys coriacea, occur in the Atlantic Ocean, but interactions with industrial fisheries could jeopardize recent positive population trends, making bycatch mitigation a priority. Here, we perform the first pan-Atlantic analysis of spatio-temporal distribution of the leatherback turtle and ascertain overlap with longline fishing effort. Data suggest that the Atlantic probably consists of two regional management units: northern and southern (the latter including turtles breeding in South Africa). Although turtles and fisheries show highly diverse distributions, we highlight nine areas of high susceptibility to potential bycatch (four in the northern Atlantic and five in the southern/equatorial Atlantic) that are worthy of further targeted investigation and mitigation. These are reinforced by reports of leatherback bycatch at eight of these sites. International collaborative efforts are needed, especially from nations hosting regions where susceptibility to bycatch is likely to be high within their exclusive economic zone (northern Atlantic: Cape Verde, Gambia, Guinea Bissau, Mauritania, Senegal, Spain, USA and Western Sahara; southern Atlantic: Angola, Brazil, Namibia and UK) and from nations fishing in these high-susceptibility areas, including those located in international waters.Work in Gabon was financially supported by the Large Pelagics Research Center through National Oceanographic and Atmospheric Agency award no.

Using Satellite Tracking to Optimize Protection of Long-Lived Marine Species: Olive Ridley Sea Turtle Conservation in Central Africa

Tractable conservation measures for long-lived species require the intersection between protection of biologically relevant life history stages and a socioeconomically feasible setting. To protect breeding adults, we require knowledge of animal movements, how movement relates to political boundaries, and our confidence in spatial analyses of movement. We used satellite tracking and a switching state-space model to determine the internesting movements of olive ridley sea turtles (Lepidochelys olivacea) (n = 18) in Central Africa during two breeding seasons (2007-08, 2008-09). These movements were analyzed in relation to current park boundaries and a proposed transboundary park between Gabon and the Republic of Congo, both created to reduce unintentional bycatch of sea turtles in marine fisheries. We additionally determined confidence intervals surrounding home range calculations. Turtles remained largely within a 30 km radius from the original nesting site before departing for distant foraging grounds. Only 44.6 percent of high-density areas were found within the current park but the proposed transboundary park would incorporate 97.6 percent of high-density areas. Though tagged individuals originated in Gabon, turtles were found in Congolese waters during greater than half of the internesting period (53.7 percent), highlighting the need for international cooperation and offering scientific support for a proposed transboundary park. This is the first comprehensive study on the internesting movements of solitary nesting olive ridley sea turtles, and it suggests the opportunity for tractable conservation measures for female nesting olive ridleys at this and other solitary nesting sites around the world. We draw from our results a framework for cost-effective protection of long-lived species using satellite telemetry as a primary tool

A comparison of the seasonal movements of tiger sharks and green turtles provides insight into their predator-prey relationship

During the reproductive season, sea turtles use a restricted area in the vicinity of their nesting beaches, making them vulnerable to predation. At Raine Island (Australia), the highest density green turtle Chelonia mydas rookery in the world, tiger sharks Galeocerdo cuvier have been observed to feed on green turtles, and it has been suggested that they may specialise on such air-breathing prey. However there is little information with which to examine this hypothesis. We compared the spatial and temporal components of movement behaviour of these two potentially interacting species in order to provide insight into the predator-prey relationship. Specifically, we tested the hypothesis that tiger shark movements are more concentrated at Raine Island during the green turtle nesting season than outside the turtle nesting season when turtles are not concentrated at Raine Island. Turtles showed area-restricted search behaviour around Raine Island for ~3–4 months during the nesting period (November–February). This was followed by direct movement (transit) to putative foraging grounds mostly in the Torres Straight where they switched to area-restricted search mode again, and remained resident for the remainder of the deployment (53–304 days). In contrast, tiger sharks displayed high spatial and temporal variation in movement behaviour which was not closely linked to the movement behaviour of green turtles or recognised turtle foraging grounds. On average, tiger sharks were concentrated around Raine Island throughout the year. While information on diet is required to determine whether tiger sharks are turtle specialists our results support the hypothesis that they target this predictable and plentiful prey during turtle nesting season, but they might not focus on this less predictable food source outside the nesting season

Jellyfish Support High Energy Intake of Leatherback Sea Turtles (Dermochelys coriacea): Video Evidence from Animal-Borne Cameras

The endangered leatherback turtle is a large, highly migratory marine predator that inexplicably relies upon a diet of low-energy gelatinous zooplankton. The location of these prey may be predictable at large oceanographic scales, given that leatherback turtles perform long distance migrations (1000s of km) from nesting beaches to high latitude foraging grounds. However, little is known about the profitability of this migration and foraging strategy. We used GPS location data and video from animal-borne cameras to examine how prey characteristics (i.e., prey size, prey type, prey encounter rate) correlate with the daytime foraging behavior of leatherbacks (n = 19) in shelf waters off Cape Breton Island, NS, Canada, during August and September. Video was recorded continuously, averaged 1:53 h per turtle (range 0:08–3:38 h), and documented a total of 601 prey captures. Lion's mane jellyfish (Cyanea capillata) was the dominant prey (83–100%), but moon jellyfish (Aurelia aurita) were also consumed. Turtles approached and attacked most jellyfish within the camera's field of view and appeared to consume prey completely. There was no significant relationship between encounter rate and dive duration (p = 0.74, linear mixed-effects models). Handling time increased with prey size regardless of prey species (p = 0.0001). Estimates of energy intake averaged 66,018 kJ•d−1 but were as high as 167,797 kJ•d−1 corresponding to turtles consuming an average of 330 kg wet mass•d−1 (up to 840 kg•d−1) or approximately 261 (up to 664) jellyfish•d-1. Assuming our turtles averaged 455 kg body mass, they consumed an average of 73% of their body mass•d−1 equating to an average energy intake of 3–7 times their daily metabolic requirements, depending on estimates used. This study provides evidence that feeding tactics used by leatherbacks in Atlantic Canadian waters are highly profitable and our results are consistent with estimates of mass gain prior to southward migration
