World Environmental Health Day: Humanity’s Shared Responsibility
Heramba Nath
World Environmental Health Day, observed every year on 26 September, is more than a symbolic mark on the calendar, it is a reminder of the inseparable bond between human health and the state of our environment. The air we breathe, the water we drink, the soil that nourishes our crops, and the ecosystems that sustain life all play vital roles in determining our collective wellbeing. Yet as the twenty-first century advances, this delicate balance faces unprecedented strain. Climate change, deforestation, unregulated industrialisation, unplanned urbanisation, plastic pollution, and unsustainable consumption patterns are pushing ecosystems to collapse, while simultaneously fuelling public health crises. The observance of this day encourages reflection, awareness, and most importantly, action to ensure that future generations inherit a planet capable of sustaining healthy lives.
The origins of World Environmental Health Day can be traced to the International Federation of Environmental Health, which initiated the day to emphasise the importance of environmental factors in shaping human health outcomes. This perspective has become increasingly relevant in recent decades as the scientific community has uncovered clear evidence linking environmental degradation to the rise of non-communicable diseases, infectious outbreaks, malnutrition, and mental health disorders. The environment does not merely form a backdrop to human activity, it is the foundation upon which all aspects of life are built. The recognition of this relationship demands that governments, civil society, and individuals view environmental protection not as an optional concern but as a fundamental pillar of public health.
In India, the urgency of this message could not be greater. The country has experienced rapid economic growth, but often at the cost of environmental safeguards. Air pollution levels in many cities remain among the highest in the world, with severe implications for respiratory illnesses, heart disease, and reduced life expectancy. The crisis of unsafe drinking water continues to plague rural and urban areas alike, leading to preventable diseases such as diarrhoea, cholera, and hepatitis. Deforestation and encroachments into natural habitats have triggered human–wildlife conflicts and biodiversity loss, destabilising ecological systems that once regulated climate and disease vectors. In Assam and the wider North East, the challenges are particularly acute. Plastic and polythene pollution choke rivers and clog urban drains, while emissions from industries and brick kilns further compromise air and water quality, increasing the risk of respiratory illnesses and other health problems. The recent decision by the Assam government to ban gutkha, pan masala, and other tobacco-laced chewing products is a commendable step in promoting public health and a safer environment. In addition, smoking in public places is prohibited by law under both state and central regulations, and everyone should obey these laws as responsible citizens. Tobacco smoke not only harms human health but also contributes significantly to air pollution. These measures together reinforce the message that environmental protection and human health are inseparably linked, and that collective action by governments, communities, and individuals is essential for a sustainable future. Frequent floods, soil erosion, and contamination of rivers continue to affect millions, while the destruction of forest cover undermines traditional livelihoods and cultural identities, highlighting the urgent need for responsible stewardship of natural resources.
Globally, the same story plays out in different forms. Rising global temperatures intensify extreme weather events, bringing droughts, cyclones, and floods that displace communities and destroy infrastructure. The melting of glaciers and polar ice caps threatens long-term water availability for billions of people. Ocean acidification and plastic waste jeopardise marine ecosystems that are vital for food security. These changes are not distant problems of future generations, they are already manifesting in hospitals and communities across the world. Doctors treating asthma, cancers linked to toxic chemicals, or malnutrition caused by crop failures are confronting the human face of environmental decline. The COVID-19 pandemic further underscored how ecological imbalance can give rise to zoonotic diseases, making global health security inseparable from environmental stewardship.
The economic costs of environmental health neglect are staggering. According to studies by international agencies, air pollution alone leads to millions of premature deaths annually, alongside significant productivity losses. Climate-induced disasters demand enormous expenditures on relief and rehabilitation, diverting resources from education, healthcare, and development. The paradox is evident, economies are undermining their own foundations by prioritising short-term industrial gains over long-term sustainability. For developing nations like India, which aspire to rapid progress, this contradiction becomes even sharper. Balancing the needs of growth with the imperatives of environmental health is not just an ethical challenge but a practical necessity. Without healthy citizens, no economy can thrive.
World Environmental Health Day also reminds us of the social justice dimension inherent in the issue. Environmental degradation disproportionately affects the poor, who are least equipped to shield themselves from its consequences. Slum dwellers exposed to contaminated water, farmers struggling with erratic monsoons, indigenous communities losing their forests, and children breathing toxic air all illustrate how vulnerable populations bear the heaviest burden. Meanwhile, those who contribute most to ecological damage often have the resources to insulate themselves from its worst effects. This inequality raises pressing ethical questions about fairness, responsibility, and intergenerational justice. Addressing environmental health therefore demands policies that are inclusive and attentive to the needs of the marginalised, not just technocratic solutions.
Science and technology offer powerful tools to confront these challenges, but they must be guided by wisdom and responsibility. Renewable energy, sustainable agriculture, clean transport, and waste management innovations hold immense promise. The expansion of solar and wind power in India is a testament to the feasibility of alternatives to fossil fuels. Similarly, organic farming movements and water conservation initiatives showcase community-driven solutions. Yet technology alone cannot solve what is fundamentally a behavioural and cultural issue. The choices individuals make about consumption, waste, and respect for nature ultimately determine the scale of environmental degradation. Education therefore plays a pivotal role, embedding environmental awareness into curricula and fostering a culture of sustainability from a young age.
For Assam and the wider North East, the observance of this day carries special resonance. The region’s fragile ecosystems, ranging from the Brahmaputra floodplains to its unique biodiversity hotspots, demand careful stewardship. Traditional practices that once harmonised with nature are increasingly eroded by modern pressures of deforestation, mining, unplanned urban expansion, and industrial and brick kiln emissions. Recurrent floods devastate health systems and livelihoods, underscoring the intimate link between environmental disruption and human suffering. Strengthening disaster preparedness, ensuring safe drinking water supply, and preserving forest cover are not just environmental goals but health imperatives for the people of this region.
International cooperation is indispensable, as environmental health challenges recognise no borders. Air pollution drifts across continents, water pollution flows downstream, and greenhouse gas emissions affect the entire planet. Agreements like the Paris Climate Accord symbolise attempts at collective action, though their success depends on the genuine commitment of nations. World Environmental Health Day thus reinforces the need for solidarity, dialogue, and accountability at the global level. For India, leadership in this arena can enhance not only its international standing but also its domestic resilience. By championing green policies and sustainable development models, the country can demonstrate that environmental health is compatible with progress.
Beyond policies and science, there lies a deeper philosophical dimension. Human beings have often acted as if they stand apart from nature, treating it as a warehouse of resources to exploit. Yet the truth is more humbling, humanity is a part of the web of life, vulnerable to the consequences of ecological imbalance. Recognising this interconnectedness calls for a cultural reawakening, one that values simplicity, restraint, and reverence for the natural world. The wisdom embedded in indigenous traditions, spiritual teachings, and ecological philosophies across cultures provides inspiration for rethinking our relationship with the Earth. Observing World Environmental Health Day can thus become not only a policy exercise but also a moment of introspection about the moral compass guiding human civilisation.
As the world marks this day, the message is unambiguous, environmental health is human health. The purity of rivers, the clarity of air, the fertility of soil, and the stability of climate are not abstract ideals but tangible determinants of survival and dignity. The threats are real, but so are the opportunities to act. Governments must enforce regulations with sincerity, industries must embrace cleaner practices, communities must revive sustainable traditions, and individuals must internalise ecological responsibility. The future remains unwritten, shaped by the decisions of the present.
World Environmental Health Day, therefore, is not just about commemorating an international observance, it is about reaffirming the truth that the fate of humanity is tied to the fate of the Earth. It is about remembering that health cannot be bought in hospitals if the environment itself is sick. It is about ensuring that children inherit not only technological marvels but also clean skies, safe water, and thriving forests. Above all, it is about recognising that in safeguarding the planet, we safeguard ourselves. With proactive steps such as Assam’s ban on gutkha, public awareness about the dangers of smoking and obedience to anti-smoking laws, global cooperation on climate accords, and sustainable innovations across nations, humanity can embrace the shared responsibility of building a healthier, more sustainable world for present and future generations.
