Animal agriculture is a growing industry worldwide as the global demand for animal products increases. This has resulted in many harmful unintended consequences for human health, the environment, and animal welfare. This paper aims to uncover the hidden costs of negative externalities by answering the question: What types of subsidies is the US government distributing to the animal agriculture industry and in what amount? This paper will begin with some background on a few of the externalities created by the animal agriculture industry focusing specifically on environmental issues of water, air, and deforestation. Once this background is established, this will show that animal agriculture is in fact a negative-externality-generating industry. Next, subsidies will be defined and the principal findings of the research will reveal the different forms of support that the US government provides to animal agriculture. Lastly, these subsidies, both direct and indirect, will be quantified.
Plastic pollution is undoubtedly one of the most pressing challenges facing humanity today. Significant action is required in order to properly address this rapidly growing threat. The Circular Economy provides a promising model for solution design in terms of responsible consumption and production. Countdown: Circular Economy Solutions is an organization created by Jasmine Amoako-Agyei focused on addressing the threat of plastic pollution in the United States and Ghana, West Africa. The first part of this report will explain the severity of the global plastic pollution crisis and challenges with recycling. It will then present the Circular Economy as a viable model for a course of action. From there it will explain the efforts of Countdown: Circular Economy Solutions over the last two with a pathway forward. This venture leveraged the greater ASU ecosystem of resources such as Walton Sustainability Solutions, Precious Plastic ASU, the Luminosity Lab, Changemaker Central, Venture Devils, Engineering Projects in Community Service (ASU), Gary K. Herberger Young Scholars Academy, KNUST, and Ashesi D: Lab.
This thesis will examine possible connection points between the health of a local environmental/climate news ecosystem and that local community’s belief in and vulnerability to the effects of climate change in Central Appalachia and Northern Virginia. The three counties that will be studied in Virginia are Arlington, Buchanan and Wise Counties. This research will be mainly a hypothesis-generating descriptive analysis of data, coupled with both interviews with researchers and local experts, in addition to observations from relevant literature about the possible connections between availability of environmental news with climate change, institutional belief and climate vulnerability data. The local history of resource extraction will also be explored. The point of this thesis is not to prove that a lack of access to strong, locally focused climate and environmental news increases vulnerability to the effects of climate change (although it does raise this as a possibility). Rather, it is to continue a conversation with journalists, media professionals and climate professionals about how to approach understanding and engaging groups left out of the climate conversation and groups who've been traditionally underserved by news media when it comes to climate information and appeals for institutional trust. This conversation is already happening, especially when it comes to the importance of the health of local, community focused news in general in Appalachia, but given the urgency and scale of the climate crisis, merits continuation and some inquiry into environmental news.
As the need for data intelligence becomes more pervasive, companies are facing a shortage of professionals with sufficient analytical skills. It is more important than ever for students in traditional business management programs to understand relevant issues in data analytics. The paper, a teaching case, is split into two parts: the business case and the teaching note. The case addresses the challenges of an electric battery company, Capsule Inc., in adopting new analytics technology. The teaching note provides relevant management concepts and technology adoption framework to analyze the case in a class setting. The case can be used to introduce students to the challenges of implementing automation software in an office, as it focuses on key issues such as process improvement, technology adoption, and cost-reduction.
Based on existing research, state wildlife agencies should be diversifying their management activities to reflect both utilitarian and biocentric values. Yet agencies are still focused primarily on managing land and wildlife resources for hunting and fishing, partly because of revenues associated with permits and licenses (Jacobson et al., 2022; Manfredo, 2008). My research examines the values which state agencies emphasize in managing wildlife and engaging the public. Public-facing agency webpages are one way to investigate the values that drive agencies’ management priorities and activities. By looking at how information is represented on their main webpages, one can infer who the intended audience is, and which values guide their actions. Thus, my research aims to analyze how state management activities and associated information—as featured on their websites—represent public wildlife values and the trend away from utilitarianism (especially hunting and fishing) toward protectionism through wildlife conservation. Specifically, I ask: How do state-level wildlife agencies present and communicate wildlife management issues and reflect their different wildlife values—ranging from utilitarianism with emphasis on recreational use and enjoyment by people toward mutualist benefits that also protect wildlife—through their websites?
Plasticizers are plastic additives used to enhance the physical properties of plastic and are ubiquitous in the environment. A class of plasticizer compounds called phthalate esters that are not fully eliminated in wastewater treatment facilities are relevant to the ecological health of downstream ecosystems and urban areas due to their ecotoxicity, tendency for soil accumulation, and the emerging concern about their effects on public health. However, plasticizer concentrations in a constructed wetland environment have rarely been studied in the United States, prompting the need for a method of plasticizer quantification in the Tres Rios Constructed Wetlands which are sustained by the effluent of the 91st Avenue Wastewater Treatment Plant in Phoenix, Arizona. The concentrations of four common plasticizer compounds (dimethyl: DMP, diethyl: DEP, di-n-butyl: DnBP, and bis(2-ethylhexyl): DEHP phthalate) at five sites across the wetland surface water were quantified using solid-phase extraction followed by gas chromatography coupled with mass spectrometry (GC/MS). The sampling period included four sample sets taken from March 2022 to September 2022, which gave temporal data in addition to spatial concentration data. Quantification and quality control were performed using internal standard calibration, replicate samples, and laboratory blanks. Higher molecular weight phthalates accumulated in the wetland surface water at significantly higher average concentrations than those of lower molecular weight at a 95% confidence level, ranging from 8 ng/L to 7349 ng/L and 4 ng/L to 27876 ng/L for DnBP and DEHP, respectively. Concentrations for dimethyl phthalate and diethyl phthalate were typically less than 50 ng/L and were often below the method detection limit. Average concentrations of DnBP and DEHP were significantly higher during periods of high temperatures and arid conditions. The spatial distribution of phthalates was analyzed. Most importantly, a method for successful ultra-trace quantification of plasticizers at Tres Rios was established. These results confirm the presence of plasticizers at Tres Rios and a significant seasonal increase in their surface water concentrations. The developed analytical procedure provides a solid foundation for the Wetlands Environmental Ecology Lab at ASU to further investigate plasticizers and contaminants of emerging concern and determine their ultimate fate through volatilization, sorption, photodegradation, hydrolysis, microbial biodegradation, and phytoremediation studies.
This thesis investigates the feasibility of using recycled ceramics as the aggregate in concrete, as an alternative to natural rock aggregates. The study evaluates the mechanical properties of concrete made with recycled ceramics and compares them with those of traditional concrete. The research involved laboratory experiments to determine compressive strength and displacement. The results show that the concrete made with recycled ceramics exhibited higher compressive strength and lower maximum displacement than traditional concrete, which means it acted more brittle. However, when the recycled ceramics were used to replace only 50% of the rock aggregate, the compressive strength decreased while the maximum displacement stayed the same, though the study concludes that a larger sample size is needed for more reliable results. Based on the findings, the thesis concludes that while the use of recycled ceramics in concrete may not be suitable for structural concrete, it could still have potential as a sustainable building material in non-structural applications.
Climate change is impacting fisheries through ecological shifts altering the geographical distribution and quantity of fish species. About 60% of United States fish caught by volume is caught in the Alaska region, with Alaska's economy dependent on fisheries. Additionally, fisheries are an important source of employment for many Alaskan communities. Therefore, it is important to have policies and strategies in place to prepare for ongoing climate impacts. One step to support better tailoring policy to support those most likely to be negatively impacted is to identify the fishing communities most vulnerable to climate change. This study uses data on vulnerable fish species and fishery catch by species and community to identify what communities are most vulnerable to changing climate conditions. I identify 26 communities that are fishing climate vulnerable species. I then use vulnerable fish species revenue data to identify communities most at risk either because they generate a substantial amount of revenue from these species or a substantial proportion of their total revenue is derived from these species. Using species-specific revenue, I show that Sablefish contribute the most to this vulnerability.
