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.

Post-disaster rebuilding often creates a massive spike in demand for construction materials, sometimes equivalent to 15 years of typical demand, which can lead to unregulated resource extraction and increased greenhouse gas emissions. The document highlights how the demand for cement and sand contributes to global CO2 emissions and ecosystem degradation, respectively. It advocates for the strategic recycling and reuse of disaster debris—such as concrete, metals, and wood—to reduce pressure on natural resources, lower costs, and create local jobs, thereby strengthening long-term community resilience.

The paper argues that Indonesia can meet rising global vegetable oil demand without further deforestation by combining yield intensification with expansion onto degraded lands, specifically alang-alang grasslands and flat secondary forests. It finds that management practices are more critical to yield than previous land use and that alang-alang grasslands offer the lowest establishment costs and fastest carbon payback times.

The report examines the environmental and social costs of global food production, specifically the conversion of natural ecosystems into agricultural land. It highlights the role of commodity markets and subsistence farming in driving deforestation and biodiversity loss, while presenting shrimp aquaculture as a potential model for conversion-free production through controlled intensification. The document calls for a collaborative effort between governments, companies, and civil society to implement traceability, regenerative agriculture, and comprehensive land-use planning to secure the planet's ecosystem services.

The report analyzes the relationship between production intensity and resource use in shrimp farming across Thailand and Vietnam. It argues that intensification—increasing output per unit area—reduces the land, water, and energy footprint per ton of shrimp, thereby offering both economic benefits to farmers and environmental protection for coastal habitats. The study highlights the Feed Conversion Ratio (FCR) as a critical indicator of both economic cost and environmental impact, particularly regarding the use of wild fish in feed. It concludes that responsible intensification is the most viable path to meeting growing consumer demand without further converting biodiverse coastal ecosystems into farms.

The report argues that transitioning to bulk milk dispensers (BMDs) in K-12 schools can significantly reduce packaging and liquid milk waste, lower waste hauling and refrigeration costs, and decrease greenhouse gas emissions. While initial startup costs and labor for cleaning reusable cups are primary hurdles, case studies indicate that these costs can be recouped through reduced waste and improved efficiency. The document highlights that BMDs can lower milk waste from roughly 32 cartons per student to 4.5 cartons per student annually, contributing to broader school sustainability goals.

The document outlines the ecological risks posed by proposed offshore oil and gas development in Alaska's Bristol Bay, focusing on the threat to the critically endangered eastern North Pacific right whale. It details how noise pollution, vessel strikes, oil spills, and invasive species could jeopardize the recovery of several endangered whale species in the region.

The document examines desalination as a potential water source for Cape Town, noting that while it provides a rainfall-independent supply, it is often the most expensive option and carries significant energy and environmental costs. It details existing small-scale plants in South African municipalities and warns against over-investing in large-scale facilities based on experiences in Australia.
