“…Similarly, [78] documented that discarded shing nets constituted the majority of sea turtle entanglements. Entanglement is identi ed as one of the major sources of mortality for sea turtles worldwide [18,78,79]. The cases of entanglement cited here are probably a very small fraction of the total entanglements that have happened in Indian waters.…”

Background: Fishing activity is a major source of marine litter on beaches, but most studies focus on recreational beaches. In this study, we assessed the abundance, composition, source and spatial distribution of marine litter on ten fishing beaches along Palk Bay, on the southeast coast of India. We also used social media to collect data on the impact of fishing litter on marine animals in the study area. Results: A total of 4,227 marine litter and their average density of 0.70 items/m2 were collected. Plastic (84.54%) is the most abundant in the study area, followed by cloths (7.46%), glass (5.19%), and rubber (3.47%). From the result, the value of CCI ranges from 6.26 to 25.7 indicating that the coast is "moderately clean" to "extremely dirty". The majority of the marine litter collected originated from fishing activity. The most common are string and cord, fishing lines, fishing gear, floats and buoys. Conclusion: The presence of this type of marine litter can produce serious environmental issues, such as ghost fishing, that impacts a large variety of marine species. A total of 25 of the olive ridley turtles (Lepidochelys olivacea) were entangled in fishing litter between 2018 and 2020. Most of the reported entanglements were due to discarded or lost fishing gear, which shows the importance of managing this type of litter in India. It is important to manage the litter related to the fishing activity by educating fishermen and organizing clean-up campaigns.

“…We expected to find American land mammals in the entanglement category, but this has not been identified in the studies consulted. This is striking given the high incidence of entanglements in marine ecosystems (Battisti and Gippoliti 2018 ; Jepsen and de Bruyn 2019 ; Donnelly-Greenan et al 2019 ; Høiberg et al 2022 ; Rodríguez et al 2022 ; Battisti et al 2023 ). However, bears with plastic feeders around their necks have been observed in social networks (MyFWC 2021 ).…”

Plastics have brought many benefits to society, but their mismanagement has turned them into a serious environmental problem. Today, the effects of plastic waste on wildlife are becoming increasingly evident. Since studies on plastic pollution have focused on species in marine ecosystems, here we review current knowledge on interactions between terrestrial mammals and plastic waste in the countries of the Americas, which is a global hotspot of mammalian biodiversity and in turn has, among its member countries, nations with high per capita generations of plastic waste globally. We identified 46 scientific articles documenting plastic ingestion in 37 species and four species that used plastic waste for nest or burrow construction. Of the 46 investigations, seven focused on plastic contamination, while the others reported on the presence of plastics in wildlife, even though this was not the primary focus of the research. However, these publications lack analytical methods commonly used in plastic studies, and only one study applied a standardized methodology for plastic detection. Therefore, in general, plastic pollution research on terrestrial mammals is limited. We extend several recommendations such as designing methodologies that are adapted to terrestrial mammals for the identification of plastics in fecal matter or gastrointestinal contents, carrying out species-specific analyzes on the impacts of plastics in nests or burrows, and giving further attention to this understudied issue and taxa.
