Geothermal Energy And Its Impacts On The Environment, Aditi Gorthy, Nathan Tran, Laureen Pierre-Louis Jan 2023

Geothermal Energy And Its Impacts On The Environment, Aditi Gorthy, Nathan Tran, Laureen Pierre-Louis

Mako: NSU Undergraduate Student Journal

From the multitude of energy sources that we have developed throughout the eons, renewable energy or “clean energy” has been on the rise to combat global warming and climate change which burning nonrenewable sources of energy have contributed to. Before geothermal energy is used as part of the mainstream energy sources some aspects must be analyzed and resolved. Unfortunately, geothermal power plants still release pollutants, such as carbon dioxide and sulfur dioxide, into the environment and cause general environmental disruptions due to drilling and changes in land formations. Recent and future studies have been and should be conducted to find …

The Impact Of Cross-Border Environmental Media And Advocacy At The Skagit River Headwaters, Derek Moscato Jul 2022

The Impact Of Cross-Border Environmental Media And Advocacy At The Skagit River Headwaters, Derek Moscato

Border Policy Research Institute Publications

The regional media of Cascadia has directed significant media attention toward the Skagit River watershed since 2018 as a result of a controversial mining proposal at the international border dividing British Columbia and Washington State. At the center of this con-troversy sits the so-called “Donut Hole” located at the headwaters of the Skagit watershed. As a result of concerns about impacts to wildlife and the surrounding North Cascades ecosystem, opposition to the project was substantial, led by environmental advocates and Indigenous community leaders. In turn, they harnessed extensive media coverage and advocacy to facilitate a larger regional dialogue about the …


Investigating The Mechanisms Driving Mercury Reduction And Emissions In Soil, Hamil Patel Jun 2022

Investigating The Mechanisms Driving Mercury Reduction And Emissions In Soil, Hamil Patel

Student Theses

The water-induced emission of mercury from soil has been studied, but a complete understanding of the mechanisms driving mercury reduction and emission in soil has not been reached. The current understanding is an immediate expulsion of soil gaseous mercury upon water treatment and an upward transport of dissolved soil ionic mercury as the water evaporates. We analyzed emissions from several types of samples using various methods to further our understanding on the mechanisms involved. Light-induced emissions from aqueous samples of humic acid (HA) spiked with mercury (II) chloride (HgCl2) showed that at higher concentrations of HA, less mercury …


Factors Influencing Conservation Knowledge: A Survey Of Residents In The United States, Samantha Helgeson, Amanda Fasching, Ashley Kneemueller, Anna Sher May 2022

Factors Influencing Conservation Knowledge: A Survey Of Residents In The United States, Samantha Helgeson, Amanda Fasching, Ashley Kneemueller, Anna Sher

DU Undergraduate Research Journal Archive

Basic principles have been established for visitors of national and state parks, but some visitors may be more aware of conservation practices than others. To understand visitor awareness, this study investigated three factors that influence the general public’s understanding of the Leave No Trace (LNT) conservation ethic: natural areas visitation, state of residence, and media consumption. Each of the factors showed statistically significant impacts on awareness of LNT, supporting our hypotheses that this knowledge will increase with a higher frequency of park visits and media consumption, and that region of residence will also impact LNT knowledge.

Stakeholder Perceptions Of Microplastics Management In Oregon, Maya A. Hurst-Mayr May 2022

Stakeholder Perceptions Of Microplastics Management In Oregon, Maya A. Hurst-Mayr

Student Research Symposium

There is currently no federal policy in the United States that specifically addresses microplastics (MPs) pollution. However, states are beginning to act on this issue; California’s SB 1422 initiates measurement of MPs in drinking water resources and Senate Bill 1263 requires the state to adopt a strategy to reduce the ecological impact of MPs in marine ecosystems. Other West Coast states like Oregon and Washington are expected to follow California’s example. It is important to know what the actors who are a part of shaping MPs policy in Oregon would see as barriers and opportunities to doing so. We conducted …

Crises of climate breakdown, ocean acidification, mass extinction, pollution and other forms of environmental degradation demand global transformation. Direct and clinical social workers are on the front lines of responses to the social consequences of these crises. They have critical skills needed for socially and environmentally sustainable solutions to these problems. Yet for the most part, direct and clinical social workers are not engaged in environmental action and do not see their work as “environmental social work.” Micro-level workers need information and resources in order to integrate environmental health in practice, and particularly tools which center the needs of the …
