Introduction Groundwater depletion in the United States has reached crisis levels in many agricultural and urban regions as aquifers drain faster than they can recharge. Despite mounting scientific evidence of accelerating loss and growing societal impacts, efforts to reform water management often face resistance from entrenched interests — including powerful agricultural lobbies and local water…
Introduction The carbon border adjustment mechanism (CBAM) is a groundbreaking climate policy designed to put a price on the greenhouse gas emissions embedded in imported products. Originating in the European Union (EU) as part of the EU’s Green Deal, CBAM aims to prevent carbon leakage — where production shifts to countries with looser climate policies…
Introduction The impact of human activity on atmospheric mercury has been dramatic. Since the beginning of the modern era around 1500 CE, anthropogenic emissions have increased the concentration of mercury in the atmosphere roughly sevenfold compared with natural baseline levels. This dramatic rise stems primarily from industrial processes like fossil fuel combustion, mining, and waste…
Introduction The circular economy is transforming how societies produce, consume, and manage resources. Unlike the traditional linear “take–make–dispose” model, the circular economy aims to eliminate waste, keep materials in use, and regenerate natural systems. As resource scarcity intensifies and climate change accelerates, the circular economy offers a science-based pathway toward long-term sustainability and economic resilience….

Although Environmental, Social, and Governance (ESG) and Corporate Social Responsibility (CSR) are often used interchangeably, they serve different purposes, operate under different frameworks, and influence decision-making in distinct ways. Clarifying the key differences…
Introduction The impact of marine heatwaves is rapidly reshaping ocean ecosystems, fisheries, and coastal economies. These prolonged periods of unusually high sea surface temperatures are becoming more frequent and intense due to climate change. As a result, the impact of marine heatwaves extends far beyond temporary warming — it alters food webs, triggers coral bleaching,…
