Earth Day: Experts on Rethinking Our Relationship with the Planet
Every year on April 22, the world pauses not out of ritual, but out of necessity. Designated as Earth Day, this day has evolved far beyond its origins as a small grassroots campaign in 1970 into a powerful global moment of reckoning, uniting over a billion people across more than 190 countries. It is a day when conversations turn into commitments, and awareness begins to translate into action. What once started as a call to acknowledge environmental degradation has now become a defining platform for shaping how humanity chooses to coexist with the planet.
In 2026, that message feels sharper and more urgent than ever. The theme, “Our Power, Our Planet,” is both a reminder and a challenge. It places responsibility not in distant institutions alone, but in the hands of every individual, organization, and government. As the world grapples with intensifying crises from climate change and deforestation to pollution and biodiversity loss the scale of the problem is undeniable. Yet so is the potential for change. Across continents, a quiet but determined shift is underway, where innovation meets intent and sustainability is no longer aspirational, but essential.
Sustainable Industry Practices
As the world grapples with environmental challenges, the role of industry has come under increasing scrutiny. In India, a country poised to become a global manufacturing powerhouse, the emphasis is shifting toward sustainable and responsible growth. Initiatives such as Make in India are not only strengthening domestic manufacturing capabilities but also encouraging industries to adopt cleaner, more efficient practices that align with global sustainability goals.
This transformation is particularly evident in sectors such as metals, energy, and infrastructure, where sustainability is becoming a key driver of innovation and competitiveness. Companies are investing in advanced technologies, circular economy models, and energy-efficient processes to reduce their environmental footprint while maintaining productivity. Increasingly, sustainability is being seen not as a regulatory obligation but as a strategic advantage that can enhance resilience and long-term growth.
Highlighting the importance of integrating sustainability into industrial growth, C. Gopalan, Founder and Chairman of Gopalan Metals, says, “As India accelerates its journey towards becoming a global manufacturing powerhouse, sustainability must remain at the core of this transformation. Initiatives like ‘Make in India’ are not just about strengthening domestic capabilities but about building a resilient, self-reliant ecosystem that reduces dependency on imports while embracing environmentally responsible practices.”
One material that is gaining prominence in this context is copper. Known for its high conductivity and 100percent recyclability, copper plays a crucial role in enabling energy-efficient infrastructure and supporting the transition to cleaner technologies. From renewable energy systems and electric vehicles to power distribution networks and smart grids, copper is integral to the modern sustainable economy.
Emphasizing this, Gopalan adds, “Copper, being 100percent recyclable, plays a critical role in enabling energy-efficient infrastructure and supporting the transition towards cleaner technologies. By leveraging advanced manufacturing processes and an integrated production ecosystem, we are committed to minimising material waste, optimising energy use, and contributing to a circular economy.”
India’s push toward sustainability is also reflected in its expanding renewable energy sector. With ambitious targets for solar and wind power, the country is investing heavily in clean energy infrastructure. This, in turn, is driving demand for sustainable materials and technologies, creating a virtuous cycle of innovation and growth. At the same time, manufacturers are increasingly focusing on responsible sourcing, waste reduction, and energy optimisation. The adoption of digital technologies, such as automation and data analytics, is enabling more efficient production processes and better resource management. These efforts are not only reducing environmental impact but also enhancing competitiveness in the global market.
Rethinking Agriculture and Ecology
Beyond industry, the sustainability conversation is expanding to include how land is managed—an area that holds immense potential for climate action. Agriculture and land use are at the heart of environmental sustainability, influencing everything from carbon emissions and water cycles to biodiversity and food security.
Ashok Kumar Jayanthi, Co‐Founder & Chairman, Hosachiguru, highlights this shift, stating, “On this World Earth Day, the climate conversation is expanding beyond emissions to include how land is being managed. In India, where forest cover stands at around 21.76percent of the total geographical area, the focus is increasingly shifting toward restoring ecological balance at the ground level.”
Across the agriculture and land-use sector, there is a growing move away from fragmented and extractive practices toward more regenerative approaches. Practices such as agroforestry, permaculture-led design, soil restoration, and water stewardship are gaining traction as they address interconnected challenges from carbon sequestration and biodiversity loss to water stress and declining soil fertility. These approaches recognize that ecosystems are complex and interconnected, requiring solutions that work with nature rather than against it.
“There is also a shift in how land is being perceived,” Ashok notes. “It is no longer viewed purely as an economic asset, but as a living system. This has led to increased adoption of integrated models that combine trees, crops, and natural cycles to rebuild soil health and ecological resilience over time.”
Sustainable practices such as reduced reliance on synthetic inputs, the use of organic methods, and innovations like biochar, biogas, and solar-powered infrastructure are becoming increasingly relevant across the sector. Techniques like syntropic farming, crop residue management, soil mulching, and improving soil carbon are helping strengthen microbial life, enhance water retention, and support long-term land productivity.
Agriculture today sits at a critical intersection; it can either remain a carbon source or evolve into a carbon sink. Regenerative land management has the potential to transform farms into climate solutions by improving soil health, recharging groundwater, supporting biodiversity, and making landscapes more resilient to changing weather patterns. The shift toward regenerative practices is not just an environmental imperative but also an economic opportunity, offering farmers more sustainable and resilient livelihoods.

“The larger opportunity lies in scaling these approaches through wider participation,” Ashok. “Long-term climate resilience will depend on how effectively individuals, communities, and institutions shift from short-term extraction to long-term stewardship of the ecosystems they are part of.”
Sustainability in Action: A Campus Perspective
While policy, industry, and agriculture play crucial roles in driving sustainability, meaningful change often begins at the grassroots level—in institutions, communities, and everyday practices. Educational institutions, in particular, have a unique opportunity to lead by example, shaping not only infrastructure but also mindsets and behaviors.
S R Sridhar, Commodore (Retd), Registrar, International Institute of Information Technology Bangalore (IIIT-B), offers a compelling perspective on how sustainability can be embedded into daily life: “Sustainability is most powerful when it is lived, not stated. At the International Institute of Information Technology Bangalore, our campus reflects this belief every day—where more than half of our energy needs are met through solar power, over 60percent of the landscape is green, and biodiversity quietly coexists with purposeful, technology-driven innovation.”
This approach goes beyond infrastructure to encompass a culture of continuous improvement and innovation. The campus integrates sustainability into its operations through initiatives such as water recycling, waste-to-compost systems, and research-driven solutions that leverage technology for environmental impact.
Sridhar elaborates, “Our journey has been shaped by consistent action—from water recycling and waste-to-compost systems to research initiatives such as IoT-enabled composting for real-time efficiency and studies on using urban greenery to mitigate pollution and rising temperatures. Being recognized with international Green University Awards for three consecutive years reinforces that sustained commitment delivers real impact.”
Such efforts demonstrate how sustainability can be both practical and scalable. By leveraging technology and fostering a culture of responsibility, institutions can create environments that are not only environmentally sustainable but also conducive to innovation and learning. Importantly, this approach also emphasizes the role of individuals—students, faculty, and staff—in driving change. Sustainability is not confined to policies or projects; it is a mindset that influences everyday decisions and behaviors.
Highlighting this philosophy, Sridhar concludes, “For us, sustainability is not a project but a practical one that grows with every student, every innovation, and every decision. As this year’s theme reminds us, ‘Our Power, Our Planet,’ the future will depend on how responsibly we use the power we already hold.”
History of Earth Day
The story of Earth Day begins in 1970 in the United States, at a time when environmental degradation was becoming increasingly visible but lacked a unified public response. Rivers were polluted, air quality was deteriorating, and industrial growth often came at the cost of ecological balance. It was against this backdrop that Senator Gaylord Nelson envisioned a nationwide demonstration to elevate environmental issues to the forefront of public discourse.

Nelson’s inspiration came in part from the devastating 1969 Santa Barbara oil spill, which highlighted the consequences of unchecked industrial activity. Determined to channel public concern into meaningful action, he mobilized students, activists, and citizens across the country. On April 22, 1970, approximately 20 million Americans took to the streets, parks, and campuses in one of the largest public demonstrations in history.
This moment marked the birth of Earth Day as a mass environmental movement. Its impact was immediate and far-reaching. The groundswell of public support led to the establishment of the United States Environmental Protection Agency and the enactment of landmark environmental legislation, including the Clean Air Act and the Clean Water Act. These measures laid the foundation for modern environmental governance and demonstrated the power of collective action in shaping policy.
Over the following decades, Earth Day continued to evolve. By 1990, it had expanded beyond the United States, mobilizing around 200 million people in more than 140 countries. This marked a turning point, transforming Earth Day into a truly global phenomenon. Today, it is coordinated by EARTHDAY.ORG and observed in over 190 countries, making it the largest civic observance in the world.
