CAFOs Uncovered
The report argues that CAFOs are propped up by taxpayer subsidies and the externalization of costs related to pollution and public health. It highlights that these operations, while producing over 50% of U.S. food animals, create massive manure management problems and antibiotic resistance. The author suggests that medium-sized and pasture-based operations are cost-competitive alternatives that would be more viable if subsidies were redirected and antitrust laws were enforced.

An Ecosystem Services Assessment of the Lake Winnipeg Watershed Phase 1 Report
The report applies an Integrated Management of Environmental Assets (IMEA) approach to evaluate the economic value of ecosystem services in southern Manitoba. It compares the current landscape, dominated by agriculture, with three reconstructed pre-settlement scenarios. The analysis finds that restoring natural environments, particularly forests and wetlands, could significantly increase annual ecosystem service values and provide cost-effective alternatives to hard infrastructure for water purification and climate regulation. The study highlights that nonpoint nutrient loading from agricultural runoff is a primary driver of Lake Winnipeg's eutrophication and argues that a balance between productive and natural landscapes is essential for the lake's health.

Nitrogen Oxide Emissions and Midwest Power Plants
The report details the impact of nitrogen oxide (NOx) emissions from coal-fired power plants in six Midwest states, highlighting that these plants account for 30 percent of total annual regional emissions. It argues that current EPA regulations, such as the summertime-only SIP call, are insufficient because they ignore wintertime pollution and exclude certain states. The document links NOx to ground-level ozone and fine particulate matter (PM2.5), which cause respiratory and cardiovascular illnesses, premature deaths, and crop yield losses. Environmental impacts include acid rain, loss of species diversity, and the Gulf of Mexico 'dead zone'. The author advocates for mandatory year-round modern emission controls, such as Selective Catalytic Removal (SCR), for all 'grandfathered' plants.

The Mississippi River Restoration & Resilience Initiative
The Mississippi River Restoration & Resilience Initiative (MRRRI) is proposed as a federal framework to address ecological decline, flood vulnerability, and pollution in the Mississippi River basin. Modeled after the Great Lakes Restoration Initiative, MRRRI would direct the EPA to collaborate with states, tribal nations, and local governments to implement an action plan focused on reducing runoff pollution, managing flood risks, and restoring wildlife habitats. The proposal highlights the economic importance of the river, which supports a $500 billion-a-year economy and 1.5 million jobs, while noting that inaction leaves communities—particularly low-income, rural, and Indigenous populations—vulnerable to environmental and financial risks.

pesp-atf-afr_report_pe-tax-code_2025-5d6f175171f58ef9.pdf
The report argues that the private equity (PE) industry uses aggressive financial engineering to extract short-term value from companies, a process facilitated by specific U.S. tax loopholes. Key mechanisms include the carried interest loophole, interest deductions, and fee waivers, which allow PE managers to pay significantly lower tax rates than ordinary workers. The document provides case studies in housing, healthcare, energy, and labor to illustrate the negative impacts of this model, such as increased hospital mortality rates, the proliferation of high-emission LNG terminals, and the degradation of manufactured housing parks.

Valuing the Ocean
The report argues that the ocean is a victim of global market failure, where the true value of its ecosystems and services is ignored. It identifies six primary threats—ocean acidification, warming, hypoxia, sea level rise, pollution, and overexploitation of resources—and emphasizes that these stressors often interact synergistically. The authors quantify the 'cost of inaction' by comparing low and high emission scenarios, estimating that avoidable damages could exceed US$ 1 trillion per year by 2100. The document advocates for a shift from traditional cost-benefit analysis to a precautionary, insurance-based risk model and calls for integrated, cross-scale ocean governance to build ecosystem resilience.

Finding Balance
The document argues that harvesting corn stover for cellulosic ethanol increases soil erosion, depletes soil carbon, and exacerbates water pollution, such as the Gulf of Mexico's dead zone. While reduced tillage helps prevent soil loss, it does not stop carbon depletion; winter cover crops are effective for nutrient capture and soil enrichment but lack widespread adoption. The author recommends that biofuel policies include environmental performance requirements and that federal research focus on the long-term sustainability of biomass use.
