Bottle with a message: The role of story writing as an engagement tool to explore children's perceptions of marine plastic litter.

As human behaviors play a crucial role in addressing the global threat of plastic pollution, it is vital to understand perceptions about marine plastic litter (MPL) and to develop interventions encouraging pro-environmental behaviors (PEBs). This study evaluates story writing as a window to explore perceptions and as an engagement activity to boost PEBs. During the COVID-19 lockdowns, schoolchildren from the East Pacific coast participated in this activity, each creating a story and answering a pre-post survey. Qualitative and quantitative analysis of 81 stories and 79 surveys show awareness of sources and impacts. Participants identified land and local pollution as significant contributors to MPL and emphasized bio-ecological impacts, reflecting concern for landscape and wildlife. While the stories presented a diversity of solutions, recycling dominated the surveys. As participants reported an increase in self-assessed knowledge and improved PEBs after this activity, it can be seen as an engagement tool to encourage behavior change.

'Windows of opportunity': exploring the relationship between social media and plastic policies during the COVID-19 Pandemic.

Plastic pollution has reached a crisis point due to ineffective waste management, an over-reliance on single-use plastic items and a lack of suitable plastic alternatives. The COVID-19 Pandemic has seen a dramatic increase in the use of single-use plastics including 'COVID waste' in the form of items specifically intended to help stop the spread of disease. Many governments have utilised COVID-19 as a window of opportunity to reverse, postpone or remove plastic policies off agendas ostensibly in order to 'flatten the curve' of COVID-19 cases. In this paper, we use novel methods of social media analysis relating to three regions (USA, Mexico and Australia) to suggest that health and hygiene were not the only reasons governments utilised this window of opportunity to change plastic policies. Beyond the influence of social media on the plastics agenda, our results highlight the potential of social media as a tool to analyse public reactions to government decisions that can be influenced by industry pressure and a broader political agenda, while not necessarily following responses to consumer behaviour.

Multi-tissue and multi-isotope (δ13 C, δ15 N, δ18 O and 87/86 Sr) data for early medieval human and animal palaeoecology.

Human isotopic ecology at its core aims to study humans as a part of their environments, as animals within an ecosystem. We are complex animals with complicated foodways and mobility patterns that are hard to address without large multifaceted data sets. As biomolecular data from archaeological remains proliferates scientists are now at the stage where we are able to collate large bodies of data and undertake complex meta-analyses and address the complexities of human ecology and past socioenvironmental dynamics. Here we present a data set of 862 entries of new primary isotopic data (37 faunal bone, 235 human enamel carbonate with a subset of 18 for 87/86 Sr, 347 human bone, 243 human bulk dentine) within a larger data set compiled from available legacy data. It contains a total of 8,910 isotopic entries from ancient humans and animals relating to diet and mobility from the late Roman period into the Middle Ages (c. 400-1200 AD). It includes carbon, nitrogen, oxygen, and strontium isotope ratios from human bone, human dentine, faunal bone, and human bioapatite from thousands of individuals, and hundreds of sites found across 26 modern countries in western Europe. Studies have previously focused on only one of these aspects, compiling data sets for one tissue, or common isotopic pairing, or focusing on a particular site or region at a smaller scale for multi-isotope multitissue studies. This is the largest and first multitissue, multi-isotope, multiproxy data set of its kind from premodern populations. In publishing this data set, we hope to inspire more synthetic and meta-analytical work on human isotopic ecology. Insights from these data should lead to greater understanding of diet, agriculture, climate change, human-animal interactions, mobility/migration, and much more in the past. It is hoped that these insights into past socioenvironmental dynamics will help inform current discourse on human-environmental interactions. There are no copyright or proprietary restrictions on the data; these data papers should be cited when these data are used in publications. Additionally, we would like to hear from other researchers who use these data sets in teaching or for their own research.
