What Is Integral Ecology, According to Pope Francis?

As Pope Leo XIV visits Lebanon — and with the 30th UN Climate Change Conference in Belém, Brazil, ending with few tangible results — it is worth revisiting the concept of « Integral Ecology », a central idea in Pope Francis’s 2015 encyclical « Laudato Si’ ». The document outlines a deeply human and inclusive vision of ecology — one that calls for both spiritual renewal and social justice.

The term integral ecology reflects a holistic approach to the relationship between humankind and the environment. It promotes a worldview where environmental, social, cultural, and spiritual dimensions are inseparable. As the French Catholic Church site explains, this concept rests on “the conviction that ecological conversion is not confined to environmental issues alone” but also draws on hope, respect for all life, and a commitment to human dignity and fraternity. The Church, in this view, bears a moral responsibility for the care of Creation.

“We forget that we are dust”

Though the notion had circulated since the 1980s, it gained renewed momentum with the encyclical “Laudato Si’”, whose title — “Praised be You, my Lord” — echoes a hymn by Saint Francis of Assisi. In this sweeping text, Pope Francis places the protection of nature at the heart of faith in the Creator.

“We grew up thinking that we were the owners [of the planet] and its masters… We forget that we ourselves are dust,” he writes, quoting Genesis 2:7. “Our own bodies are made of the same elements as the Earth; its air gives us breath, and its water gives us life.”

From there, Francis offers an unsparing diagnosis of the global environmental crisis in a chapter titled “What Is Happening in Our Common Home.” He condemns the devastating impact of human progress on the planet: pollution, climate change, water scarcity, biodiversity loss, and the social and moral costs that accompany them.

“If we accept that human beings are creatures of this world, entitled to live and be happy,” he writes, “we cannot ignore how environmental degradation, today’s development model, and the throwaway culture shape human lives.” The encyclical also points to deep global inequality and the weakness of political and collective responses.

Where Science Meets Faith

One of the boldest sections of “Laudato Si’” calls for dialogue between science and religion. Pope Francis recognizes that many see the two as opposed, yet he argues that they can illuminate each other. “No branch of science, and no form of wisdom — not even religious wisdom — should be excluded,” he writes.

In this spirit, Francis aligns himself with the findings of the UN’s Intergovernmental Panel on Climate Change (IPCC), which attributes global warming to human activity. He blames not only technology and the illusion of control it brings, but also globalization and its tendency to impose uniform lifestyles and values.

One Crisis, Not Many

For Francis, the 21st-century crisis is not divided between environmental and social concerns — it is one and the same. Pollution, poverty, exclusion, and the exploitation of resources are interconnected symptoms of a single, global disorder.

This is the essence of integral ecology: the world is a network of relationships, and the well-being of one part depends on the whole. The Pope calls for comprehensive solutions that weave together natural ecosystems, social justice, and cultural renewal.

He insists that ecology must also be “cultural.” Every community, he says, must be engaged in finding solutions rooted in its own traditions and wisdom. Losing a culture, Francis warns, can be as serious as losing a species.

“Laudato Si’” also brings ecology down to the human scale — to daily life and relationships. For Francis, ecological awareness is not just global or institutional; it’s personal. It shapes neighborhoods, housing, public spaces — the fabric of ordinary existence.

“What Kind of World Do We Want to Leave?”

At the heart of Pope Francis’s reflection lies the question of the common good — the conditions that allow every person and community to thrive. He highlights three pillars: human dignity, the strength of intermediary institutions like the family, and social peace founded on justice and inclusion.

The State, he reminds us, must protect this common good as the bedrock of a balanced society, even as inequality continues to grow worldwide.

Finally, “Laudato Si’” looks toward future generations, asking the question that runs through the entire text: What kind of world do we want to leave for them?

This is more than an ecological question; it is a moral and cultural one. Confronted with the rise of individualism and weakened social bonds, Francis urges a shift from self-interest to shared responsibility — through international cooperation, fairer public policy, greater transparency, and genuine dialogue between science and faith.
