Sustainability: The Future Is Plant-Based, Megan R. Webber

School of Communications Undergraduate Research

“The Earth is what we all have in common.” -Wendell Berry

The state of the declining environment and the rapid climate change occurring has caused unease in the conversation of long-term human sustainability. There has recently been growing interest in the possibility of the vegan diet having a positive impact on resource sustainability. The research in this area has been a widely developing topic in the past twenty years and the evidence of the vegan diet slowing down resource waste and pollution has led to hope that the climate change can be slowed. The methods of the following research were …

Water Quality Of The Cache River Watershed, Arkansas: Contributions Of Agricultural Activity In Sub-Watersheds To Nutrient, Sediment And Lead (Pb) Contamination And Potential Toxicity Implications To Aquatic Organisms, Mary Katherine Kilmer

Student Theses and Dissertations

As the world population grows and agricultural production expands, increased stress is placed on many waterways. Water quality is often degraded and can serve as a source for areas of downstream environmental impacts. Of particular concern is the Gulf of Mexico hypoxic zone, a result of agricultural inputs from the Mississippi River Basin. One watershed identified as a potential source for this hypoxic zone is the Cache River Watershed in northeastern Arkansas. This watershed has approximately 67% of its land in row-crop production. Waterways within this watershed have poor water quality because of excessive turbidity, nutrients, pathogens and metals. In …

The Influence Of Tropical Forests And Climate Change On The Fates Of Select Organic Pollutants In A Jamaican Watershed, Kayon Barrett

USF Tampa Graduate Theses and Dissertations

Many organic compounds, although beneficial, are associated with negative health and ecological impacts. It is therefore imperative to understand the environmental fates of these contaminants. Whereas the fates and health impacts of many persistent organic pollutants have been extensively examined, there is limited research characterizing the fates of these and the less persistent organic compounds in tropical multi-use watersheds. This study therefore aimed to evaluate the roles of forests and climate change on the environmental fates and health impacts of select organic chemicals in the Rio Cobre watershed, a tropical river basin in Jamaica. A total of 16 organic compounds …

An Open-Sourced Statistical Application For Identifying Complex Toxicological Interactions Of Environmental Pollutants, Jordan T. Perkins, Michael C. Petriello, Li Xu, Arnold J. Stromberg, Bernhard Hennig

Superfund Research Center Faculty Publications

The rising number of chemicals that humans are exposed to on a daily basis, as well as advances in biomonitoring and detection technologies have highlighted the diversity of individual exposure profiles (complex body burdens). To address this, the toxicological sciences have begun to shift away from examining toxic agents or stressors individually to focusing on more complex models with multiple agents or stressors present. Literature on interactions between chemicals is fairly limited in comparison with dose-response studies on individual toxicants, which is largely due to experimental and statistical challenges. Experimental designs capable of identifying these complex interactions are often avoided …

Murray Energy Corporation V. Mccarthy, Sarah M. Danno

Public Land & Resources Law Review

Holding that the widespread effects of environmental regulation on the coal industry constituted sufficient importance, the Northern District of West Virginia ordered the Environmental Protection Agency to conduct analysis on employment loss and plant reduction resulting from regulatory effects. In admonishing the EPA’s inaction, the court ruled that the Agency had a non-discretionary duty to evaluate employment and plant reduction. Furthermore, the court held that the EPA’s attempt to put forth general reports in place of required evaluations was an invalid attempt to circumvent its statutory duty.

Transformation, Wallace M. Meyer Iii

EnviroLab Asia

Prior to leaving for Claremont Colleges’ Envriolab Asia trip to Malaysia and Singapore, I was conflicted by the question: Do we have the moral authority to interfere with resource extraction and oil-palm development in SE Asia? At that time, the trip seemed imperialistic. Why should people from Malaysia, Indonesia or any developing SE Asia country listen to a group of liberal arts college faculty from a city where widespread habitat modifications have led to significant loss of native habitats, declines in biodiversity, and changes in how these ecosystems function? Many observations transformed my opinion and have inspired me to advocate …

Ammonia And Carbon Dioxide Emissions Of Three Laying-Hen Housing Systems As Affected By Manure Accumulation Time, Timothy A. Shepherd, Hongwei Xin, John P. Stinn, Morgan D. Hayes, Yang Zhao, Hong Li

Biosystems and Agricultural Engineering Faculty Publications

Laying-hen housing design and management are the most significant factors affecting the generation and release of gaseous ammonia to the atmosphere. Transitioning the hen housing type from traditional high-rise (where manure is stored within the house for about one year) to modern manure-belt style (where manure is removed every 1 to 4 d and placed into long-term storage) has significantly improved in-barn air quality and reduced farm-level ammonia emissions. As a direct result of the advantages, 100% of new construction for U.S. egg production incorporates manure-belt systems that regularly remove manure from the houses. However, manure-belt system designs (e.g., active …

An Exploratory Study On The Possible Effect Of Hydraulic Fracturing Activities On Air Quality In The Eagle Ford Shale Region Of Texas., Laura B. Fimibama

Electronic Theses and Dissertations

Eagle Ford Shale (EFS) play is one out of five major oil and gas formations in Texas, found in the South-Eastern region with approximately 30 counties. In addition to natural gas, it produces crude oil and petroleum liquids which in recent times has resulted in a surge in drilling due to a new drilling technology – hydraulic fracturing that injects massive quantities of water along with sand and chemical additives into a well to create tiny hairline cracks in rock formations. The success of this technology has made gas extraction more economically feasible. However, this technique has generated an array …

Green Chemistry: Progress And Barriers, Sarah A. Green

Michigan Tech Publications, Part 1

Green chemistry can advance both the health of the environment and the primary objectives of the chemical enterprise: to understand the behavior of chemical substances and to use that knowledge to make useful substances. We expect chemical research and manufacturing to be done in a manner that preserves the health and safety of workers; green chemistry extends that expectation to encompass the health and safety of the planet. While green chemistry may currently be treated as an independent branch of research, it should, like safety, eventually become integral to all chemistry activities. While enormous progress has been made in shifting …

Impact Of Upper-Tropospheric Temperature Anomalies And Vertical Wind Shear On Tropical Cyclone Evolution Using An Idealized Version Of The Operational Gfdl Hurricane Model, Robert E. Tuleya, Morris Bender, Thomas R. Knutson, Joseph R. Sirutis, Biju Thomas, Isaac Ginis

CCPO Publications

The GFDL hurricane modeling system, initiated in the 1970s, has progressed from a research tool to an operational system over four decades. This system is still in use today in research and operations, and its evolution will be briefly described. This study used an idealized version of the 2014 GFDL model to test its sensitivity across a wide range of three environmental factors that are often identified as key factors in tropical cyclone (TC) evolution: SST, atmospheric stability (upper-air thermal anomalies), and vertical wind shear (westerly through easterly). A wide range of minimum central pressure intensities resulted (905-980 hPa). The …

Panarchy Use In Environmental Science For Risk And Resilience Planning, David G. Angeler, Craig R. Allen, Ahjond S. Garmestani, Lance H. Gunderson, Igor Linkov

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Environmental sciences have an important role in informing sustainable management of built environments by providing insights about the drivers and potentially negative impacts of global environmental change. Here, we discuss panarchy theory, a multi-scale hierarchical concept that accounts for the dynamism of complex socio-ecological systems, especially for those systems with strong cross-scale feedbacks. The idea of panarchy underlies much of system resilience, focusing on how systems respond to known and unknown threats. Panarchy theory can provide a framework for qualitative and quantitative research and application in the environmental sciences, which can in turn inform the ongoing efforts in sociotechnical resilience …

Environmental Fullerene Chemistry: Elucidating Critical Reaction Pathways And Resulting Products In The Aqueous Phase, Jiewei Wu

McKelvey School of Engineering Graduate Student Theses & Dissertations

As the production of fullerenes and fullerene-based materials approaches industrial scale, there are increasing interests/concerns regarding their (potential) environmental impact(s) upon release. To date, a number of critical, aqueous-based fullerene transformation pathways under environmentally relevant conditions remain poorly understood. Comprehensive, fundamental, and quantitative understanding of the potential (major) reaction pathways and resulting products of fullerene materials, particularly in aquatic systems, is now crucial for their accurate fate, transport, life cycle, risk assessment(s), and thus ultimate material sustainability.

Herein, this dissertation is focused on identifying and elucidating aqueous transformation pathways of fullerene materials, focused on C60 as a model fullerene, under …

The commercial-grade kitchens found in the Randall Dining Commons (RDC) of Sandhu Conference Center are frequently used to prepare food for students for every meal, seven days a week. The RDC kitchen facility has staff working around the clock and high consumption electrical, water, and gas appliances constantly running to parallel the high demand. The frequent use of commercial kitchen appliances results in an enormous consumption of energy and water resources leading to comparably high utility bills. Measuring the energy …

Impacts Of Environmental Quality On The Demographics Of Three Nations, Emily Hummel

Honors Projects

This study will examine how the correlation between air and water quality and the population demographics of India, South Africa, and the United States. India is a country with a growing population, increasing income inequality, and gender roles that reflect its status as a developing nation. South Africa is much smaller in area and the population is beginning to level off, but South Africa’s income inequality is growing much faster than India’s and gender inequality is less of an issue in South Africa. The population of the United States is decreasing and gender roles are fairly equal, despite income inequality …

Luck, Berta Martin-Lopez, Barbara Muraca, Bryan Norton, Konrad Ott, Et Al.

Environment and Society Faculty Publications

A cornerstone of environmental policy is the debate over protecting nature for humans’ sake (instrumental values) or for nature’s (intrinsic values) (1). We propose that focusing only on instrumental or intrinsic values may fail to resonate with views on personal and collective well-being, or “what is right,” with regard to nature and the environment. Without complementary attention to other ways that value is expressed and realized by people, such a focus may inadvertently promote worldviews at odds with fair and desirable futures. It is time to engage seriously with a third class of values, one with diverse roots and current …

The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown

Journal of Environmental and Resource Economics at Colby

This paper looks at the impact of electric vehicles on CO2 emissions specifically based on the type of electricity used in each New England state analyzed. The research looks at the question of whether or not emissions will in fact be lowered as electric cars start to take the majority of vehicles used instead of the conventional cars that take up a much larger percent of the motor vehicles used today. Taking into account the use of electricity and how many sources of electricity also release a substantial amount of emissions, we see how valid the public opinion of electric …

Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff

Journal of Environmental and Resource Economics at Colby

This paper examines the use of policy mechanisms to increase renewable energy consumption within the United States. In order to effectively measure the change of renewable energy consumption, I analyze two initiatives that promote energy consumption from renewable sources and overall increases in energy conservation. Colorado and Washington had approved initiatives in the years 2004 and 2006, respectively. Although the results are not entirely statistically significant, I find that the initiatives lead to increases in total renewable energy consumption and decreases in total energy use.

Moocs And The Online Delivery Of Business Education: What's New? What's Not? What Now?, Jonathan W. Whitaker, J. Randolph New, R. Duane Ireland

Management Faculty Publications

Although the past 2 decades have produced much promise (and accompanying research) on the use of information technology (IT) in business school courses, it is not entirely clear whether IT has truly "transformed" management education. There are compelling arguments on both sides. On one hand, advocates for the transformative role of IT can point to several success stories. On the other hand, skeptics of the role of IT in management education can also point to support for their view. This lack of consensus has led researchers in Academy of Management Learning & Education to call for scholars to confront the …

Relationship Between Sustainable Environmental Practices And Sustainable Value Creation: A Conceptual Study On Readymade Garments Industry Of Bangladesh, Mohammed S. Chowdhury, Zahurul Alam, Mizanur Rahaman Chowdhury
