Air Quality Index and Lung Health: Why the Claim of “No Direct Correlation” Is Scientifically Unsound

-

On December 18, 2025, the Minister of State for Environment and Climate Change, Kirti Vardhan Singh, told the Rajya Sabha that there is “no direct correlation between higher Air Quality Index (AQI) levels and lung diseases” and that no “conclusive data” exists to establish such a link. While this statement may appear cautious or technical on the surface, it fundamentally misrepresents how public health science understands causation and risk. More importantly, it stands in direct contradiction to decades of peer-reviewed scientific research, global health authority assessments, and clinical evidence. The suggestion that poor air quality, as measured by AQI, lacks a proven connection to lung disease risks normalising exposure to polluted air and undermines urgent public health action in a country already facing a severe air pollution crisis. Understanding What AQI Actually Measures The Air Quality Index is not an abstract or arbitrary indicator. It is a scientifically designed tool tha...

The Aravalli Issue: India’s Oldest Mountains at the Crossroads of Law, Ecology, and Development

-

Across north-western India stretches a low, weathered chain of hills that rarely commands public attention, yet silently sustains the lives of millions. The Aravalli Range, among the oldest mountain systems on Earth, lacks dramatic peaks or snow-capped summits. Its slopes are gentle, its ridges fragmented, and its presence often underestimated. But beneath this modest appearance lies one of India’s most critical ecological foundations. Today, the Aravallis stand at a decisive moment, threatened by decades of mining, deforestation, urban expansion, and regulatory neglect. The unfolding crisis, commonly referred to as the “Aravalli Issue,” is not marked by sudden catastrophe but by slow ecological unravelling, manifesting as groundwater collapse, worsening air pollution, rising temperatures, and the steady advance of desertification. Understanding this issue is essential not only for environmental awareness but for grasping the long-term sustainability of North India itself. An Ancient...

Celebrating Christmas Sustainably: Integrating Faith, Responsibility, and Care for Creation

-

Christmas is one of the most widely celebrated festivals worldwide, uniting families, faith institutions, schools, and communities in shared joy and reflection. At its core, Christmas symbolises humility, compassion, generosity and hope. Traditionally, it is a season that emphasises care for others, gratitude for what we have, and responsibility towards the wider world. However, the way Christmas is celebrated at a mass level today often stands in contrast to these values. Large-scale celebrations increasingly rely on excessive material consumption, short-term use of resources, high energy demand and poor waste management, creating environmental pressures that are rarely visible during the festive moment itself. Celebrating Christmas in an eco-friendly manner does not mean reducing joy, warmth or tradition. Rather, it means consciously aligning celebration practices with the deeper message of the festival, ensuring that joy does not come at the cost of environmental degradation, clima...

Iceland Sounds the Alarm: The AMOC Threat Becomes a Global Security Crisis

-

In an unprecedented declaration that has already begun to reshape global climate policy debates, Iceland has officially classified the potential collapse of the Atlantic Meridional Overturning Circulation (AMOC) as a national security threat . No country in modern history has ever elevated a climate tipping point to this level. Governments have long treated climate change as primarily an environmental or developmental challenge, but Iceland has broken that convention. Its decision acknowledges something scientists and governments have been reluctant to say explicitly: A destabilizing AMOC is not only an environmental problem. It is a geopolitical, economic, humanitarian, and security crisis in the making. The statement coming from Reykjavík (the Capital and largest city of iceland) is profound not only because Iceland sits at the frontline of the AMOC system, but because the AMOC itself, Earth’s great ocean circulation engine, is one of the most important and vulnerable components ...
