Earth Day, Scarcity, and Responsibility
Earth Day reframed: scarcity, global interdependence, and responsibility. This article explores the human cost of resource extraction, the urgency of e-waste recycling, and how urban mining can reduce dependency, emissions, and inequality in global supply chains.
Earth Day is often framed as a call to protect the planet. It should also be a call to think about scarcity and interdependence.
The materials that power our modern lives — in batteries, electronics, and renewable energy systems — are finite, unevenly distributed, and increasingly caught up in geopolitical tension. Scarcity is no longer only an environmental issue. It is also an economic, social, and moral one. In a world shaped by limited resources, dependence on others is unavoidable. And dependence creates responsibility.
That responsibility begins with the human cost of extraction.
When I was working in Burkina Faso, I met young people living on the street who saw artisanal gold mining as one of the few available ways to earn money. I remember one boy who had left his village in search of opportunity and was drawn north by the promise of gold. He returned months later no better off. In many places, when options are limited, extraction becomes a path toward survival before it ever becomes a strategy for development.
That is true in West Africa for gold. It is also true in parts of Central Africa for minerals that feed the global electronics and battery economy. The clean-energy transition and the digital economy require copper, lithium, nickel, cobalt, and rare earth elements. The International Energy Agency has warned that recycling is becoming indispensable to the security and sustainability of critical mineral supply. In one IEA scenario, scaling recycling reduces new mine development needs by 2050 by 40% for copper and cobalt, and by 25% for lithium and nickel.
That should change the way we think about recycling. Recycling is not only a matter of waste reduction or corporate ESG. It is also an asset for self-reliance - a way to recover value already in circulation, reduce dependency on fragile supply chains, and build resilience from what we already have. Today, the world generates 62 million tonnes of e-waste each year, yet only 22.3% is documented as formally collected and recycled. The rest represents not only a pollution risk, but also a vast economic loss: the 2022 stream contained an estimated $62 billion in recoverable resources.
But if materials recovery is part of the answer, extraction remains part of the problem.
Too often, the people closest to the source of these materials bear the greatest human cost while capturing the least long-term benefit.
The materials inside a discarded laptop in New York and the materials pulled from the ground in Congo are part of the same global story. That is why Earth Day should push us in two directions at once.
First, we need safer, more formal, and more equitable artisanal and small-scale mining in developing countries. That means taking child labour seriously, protecting workers, investing in communities, and making sure that resource wealth contributes to long-term human development rather than short-term extraction. In business terms, this cannot remain rhetorical. The UN Guiding Principles on Business and Human Rights make clear that companies have a responsibility to prevent and address adverse human rights impacts linked to their operations and value chains, and that when abuses occur, people must have access to effective remedies.
Second, we need to mine the e-waste already sitting in our homes, offices, warehouses, and data centers in developed countries. Urban mining is not a slogan anymore. It is a practical industrial strategy. The IEA notes that recycled minerals such as nickel, cobalt, and lithium can carry far lower greenhouse-gas emissions than primary supply from mining, while expanded recycling improves supply security over time.
This is where our work at WALTER fits in. One of our purposes is to create job opportunities in the e-waste industry for young adults facing barriers to employment. For me, that is not separate from the global resource conversation. There is a parallel between the struggles of marginalized young adults here and the struggles of young people elsewhere who enter dangerous forms of extraction because the alternatives are too few. All are pursuing the same things: dignity, income, freedom, and some control over their future.
The recycling industry now sits at the intersection of competition and cooperation. Countries and companies compete for limited resources. But recycling opens a different possibility: that we can reduce pressure on new extraction while building local capacity, local jobs, and local resilience. That is not only good environmental policy. It is also better industrial policy, and, when done with dignity and decent work in mind, better social policy too.
I once heard someone say: “I do not share what I have because I have too much, but because they do not have.” Scarcity creates interdependence. Interdependence calls for responsibility: for ourselves, for our communities, and for the people we will never meet whose labor is hidden inside the products we use every day.
“That is the challenge of Earth Day: to see recycling for what it has become, not a side issue of waste management, but a strategic, social, and moral response to scarcity.”
