Articles on biodiversity, ecosystems, environmental pollution, waste management, and circular economy solutions. This section explores environmental protection, ecosystem conservation, air and water pollution, and strategies to reduce environmental impacts.
Introduction The Mercury and Air Toxics Standard rollback marks a significant shift in US environmental policy. In February 2026, the Environmental Protection Agency under the Trump administration announced plans to weaken federal limits on mercury and hazardous air pollutants from coal-fired power plants. Mercury is a persistent, bioaccumulative neurotoxin. It impairs brain development in infants…
Glyphosate is the most widely used herbicide in modern agriculture. It underpins industrial farming systems, shapes food production, and sits at the center of intense public debate about cancer risk, environmental damage, and regulatory policy. Since its patenting in 1974 as Roundup, glyphosate use has expanded dramatically. Today, it is sprayed on nearly 300 million…
California atmospheric rivers now define the state’s water future. These intense moisture corridors can erase drought deficits in weeks, yet they also threaten dam safety, trigger floods, and destabilize wildfire-scarred slopes. In recent years, California has shifted from multi-year megadrought to record-breaking precipitation within a single winter. This volatility is not random. It reflects changing…
Indigenous climate knowledge is increasingly recognized as a critical component of effective climate adaptation and resilience strategies. For centuries, Indigenous Peoples have observed ecological shifts, managed landscapes, and adapted to climatic variability through place-based systems of knowledge. Today, integrating Indigenous climate knowledge into modern policy frameworks can strengthen biodiversity protection, disaster preparedness, and sustainable resource…
Introduction Has Earth crossed a homeostatic tipping point — a threshold beyond which planetary systems can no longer self-regulate effectively? The concept of a homeostatic tipping point refers to the limits of Earth’s natural ability to stabilize temperature, carbon cycles, biodiversity, and atmospheric composition. As climate change accelerates and ecosystems face mounting stress, scientists are…
Introduction Sustainable food systems are essential for feeding a growing global population without degrading ecosystems, accelerating climate change, or deepening inequality. Today’s food production accounts for roughly one-third of global greenhouse gas emissions while also driving biodiversity loss and water stress. Therefore, building sustainable food systems is no longer optional—it is a scientific, economic, and…
