Global Pandemics and the Environment

This edition highlights research from across the University of Wisconsin-Madison campus, with articles detailing the impact that reduced human activity during periods of quarantine had on wildlife and air pollution. The final entry details how diseases like COVID-19 have been transmitted from wildlife to humans, and how increased human activity amplifies the chances of transmission in the future.

Environmental Justice and Environmental Racism

This issue features research on the differential impacts of air pollution, the justice impacts that stem from addressing climate change, and the impacts of mercury across the landscape. We also highlight attempts to center environmental justice within environmental education. We close with a story from a manoomin (wild rice) researcher who shares her connection with an indigenous community and how that connection shaped her research.

Nitrate Contamination in Drinking Water and Groundwater

Safe drinking water has become a major bipartisan priority in Wisconsin. Governor Tony Evers has declared 2019 the year of Safe Drinking Water and Assembly Speaker Robin Vos has commissioned a taskforce on water quality. This inaugural edition of the Nelson Institute for Environmental Studies Issue Brief focuses on the most widespread groundwater contaminant: Nitrates. This is an environmental and public health hazard faced by Wisconsinites statewide.
