The world today faces a crucial choice: invest in life or in death. On one side, the ecological transition needed to protect creation and future generations; on the other, the arms race consuming precious resources and sowing destruction. A recent study by geographer Julie Klinger and her team, presented at the OECD forum on critical minerals in Istanbul, highlights a disturbing reality: the same raw materials needed for renewable energy—lithium, cobalt, copper, and rare earths—are increasingly being diverted to the weapons industry. This competition is not just economic but also ethical and spiritual.
As Christians, we are called to be stewards of creation (Genesis 2:15). The Bible reminds us that "the earth is the Lord's" (Psalm 24:1) and that we have a responsibility to manage it wisely. Choosing to prioritize weapons over clean energy is not just a political mistake but a sin against creation and against the poor, who are the first to suffer from climate change and armed conflict.
Critical Minerals: A Resource Contested Between Life and Death
Klinger's study shows how elements like lithium and cobalt are essential both for electric vehicle batteries and solar panels, and for drones, missiles, and tanks. While renewable energy production proceeds slowly, global military spending exceeded $2.8 trillion last year, far more than the $2.4 trillion needed for the energy transition. This disparity is not just numerical—it is a matter of moral priorities.
Jesus teaches us: "Blessed are the peacemakers, for they will be called children of God" (Matthew 5:9). Investing in war means sowing the wind and reaping the whirlwind. The arms race not only diverts resources from caring for the planet but also fuels a cycle of violence that contradicts the Gospel. The prophet Isaiah envisioned a time when nations would "beat their swords into plowshares" (Isaiah 2:4). Today, sadly, we see the opposite: plowshares are being turned into swords.
The Human and Environmental Cost
It's not just about numbers. Behind every ton of lithium or cobalt extracted are communities suffering the environmental impact of mining, often in poor countries. When these resources are directed to war, the damage multiplies: not only is the environment degraded, but conflicts are fueled that cause death, refugees, and destruction. The psalmist cries out: "How long, Lord, will the wicked triumph?" (Psalm 94:3). As believers, we cannot remain indifferent.
A Call to Ecological Conversion and Peace
The ecological transition is not just a technological challenge but a conversion of the heart. Pope Francis, in Laudato Si', urged us to "hear both the cry of the earth and the cry of the poor." The recent Pope, Leo XIV, has continued this path, emphasizing the urgency of peace founded on justice and care for creation. The Church invites us to rethink our development model, prioritizing life over profit and military power.
The question we must ask is: what are our priorities as a society? Are we investing in what builds up or what destroys? Scripture warns us: "Do not store up for yourselves treasures on earth, where moth and rust destroy" (Matthew 6:19). Weapons are fleeting treasures that bring only death. Renewable energy, on the other hand, is an investment in the future, a way to care for our common home.
An Appeal to Action
Faced with this reality, what can we do? First, inform ourselves and raise awareness. Awareness is the first step toward change. Second, support policies that promote peace and the ecological transition. Third, pray for peace and act as agents of reconciliation in our communities. As Christians, we are called to be light and salt in a world that often chooses the path of death. May the Lord give us wisdom and courage to choose life.
