The Problem of Distance

Human moral instincts evolved in small groups, geared towards immediate kin and short time horizons. Climate change defies these instincts. Its worst effects are delayed, dispersed, and uncertain. The people most affected by today’s emissions are those who cannot vote, protest, or even speak—they do not yet exist.

Yet philosophy offers tools to think beyond the present. Utilitarian thinkers like Peter Singer argue that the suffering of future individuals counts equally to that of current ones, provided it is foreseeable. John Rawls, in his theory of justice, introduced the “veil of ignorance”: if we didn’t know when we would be born, we’d rationally prefer to live in a world where the future is preserved, not plundered.

Still, political systems remain rooted in the short term. Election cycles, corporate earnings reports, and consumer habits all reward immediate gratification. The result is a systemic bias against the future—a moral blind spot baked into the machinery of modern life.

Inheriting the Bill

There is a term economists use: externality. It describes the costs of an action borne not by the doer, but by others. Climate change is the ultimate externality. Every ton of carbon emitted today adds to a global tab that someone else—often poorer, younger, or unborn—must pay.

This is not just an abstract injustice. It is a material one. Industrialised nations built their wealth on fossil fuels; developing nations are told to decarbonise. The current generation enjoys cheap energy, fast fashion, and meat-heavy diets, while the next inherits the floods, famines, and mass extinctions.

Philosophically, this creates a stark asymmetry. The living exercise power over the non-existent, yet the reverse is impossible. This violates the Kantian principle of treating individuals as ends in themselves. Future people are used as means to present comfort—silenced by chronology.

Youth as Moral Witnesses

Yet the future is not entirely voiceless. In recent years, children and adolescents have emerged as unlikely prophets of the climate movement. From Greta Thunberg to Fridays for Future, the young have taken to the streets with placards, speeches, and lawsuits—not to ask for luxuries, but for a livable planet.

This reversal of moral authority is striking. Typically, elders instruct the young in virtue. Here, the young indict the old for moral negligence. Their message is not technocratic but ethical: that it is wrong to mortgage the future for convenience, and worse to pretend the debt does not exist.

Such activism reveals an intuitive grasp of intergenerational justice. It also highlights the emotional cost: eco-anxiety, grief, and a pervasive sense of betrayal. We are raising a generation burdened with cleaning up a mess they did not make.

A Justice That Crosses Time

So what would a just response look like? It begins with acknowledging that sustainability is not just an engineering challenge—it is an ethical imperative. Policies such as carbon pricing, green investment, and international climate finance are not only pragmatic—they are moral acts of reciprocity.

More fundamentally, we need a cultural shift. To think in decades, not quarters. To measure success not by GDP, but by what we leave behind. This is hard in a society addicted to speed and novelty. But perhaps the ancient concept of stewardship—the idea that the world is not ours to exploit, but to protect for others—offers a guide.

In the end, the question of what we owe the future is a test of our imagination and empathy. Can we act on behalf of people we will never meet, whose names we will never know? If so, we will have passed not just a climate threshold, but a moral one.
