To what extent should humans interfere with the ecosystem?

This question touches on a tension that Christians often feel. On one hand, humans have undeniably caused widespread ecological harm through pollution, deforestation, habitat destruction, and climate change. On the other hand, actively altering ecosystems in the name of conservation can feel invasive, or like we are “playing God”. Should we simply leave nature alone to heal by itself? Or should we actively intervene to restore what has been damaged?

What Scripture Says

From a biblical perspective, the issue is not whether humans should influence creation, but how and why we do so. Human influence in creation is part of God's design; the problem arises when our influence is driven by greed, pride, or exploitation rather than love and faithful stewardship.

Humanity's original calling was active stewardship: From the very beginning, God entrusted humanity with a unique role in creation. Genesis 1:27-28 tells us what that role should look like.

“So God created man in his own image, in the image of God he created him; male and female he created them. And God blessed them. And God said to them, “Be fruitful and multiply and fill the earth and subdue it, and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth.” (Genesis 1:27-28, ESV)

Here, being made in the image of God refers to acting as His representatives - godly dominion thus sees humanity not as the rulers of creation but as vice-regents acting on behalf of the true ruler, stewarding creation just as He commands us to. Furthermore, throughout Scripture, good rulers exercised authority for the flourishing of those under their care, reflecting God's own character. (Psalm 72) Dominion is therefore best understood as responsible stewardship, not exploitation. At the same time, Genesis 2:15 assures us of this truth.

“The LORD God took the man and put him in the garden of Eden to work it and keep it.” (Genesis 2:15, ESV)

In the original Hebrew, "work" (abad) meant "serve" or “cultivate,” while "keep" (shamar) also meant "guard," "watch over," or "protect." Humanity's vocation was therefore never passive preservation nor unrestricted domination, but serving and protecting God's creation while enabling it to flourish.

However, sin distorted our relationship with creation: human interference has become destructive because of sin. Instead of cultivating creation for God's glory, humanity often seeks short-term gain at creation's expense. This has contributed to unprecedented environmental challenges, including biodiversity loss, habitat fragmentation, pollution, and climate change. According to the Intergovernmental Panel on Climate Change, human activities have unequivocally warmed the atmosphere, oceans, and land, leading to increasingly severe impacts on ecosystems worldwide. Meanwhile, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services estimates that around one million species face extinction, many due to human activity.

These realities remind Christians that creation care is not merely about aesthetics—it is about addressing the consequences of human sin that affect both people and the rest of creation.

Sometimes faithful stewardship requires intervention: because creation has been damaged, loving stewardship often requires active restoration, not simply leaving ecosystems untouched.

Examples include:

• Restoring mangrove forests that protect coastlines and provide habitat for wildlife.
• Removing invasive species that threaten native biodiversity.
• Reforesting degraded landscapes.
• Cleaning polluted rivers and coastlines.
• Reintroducing locally extinct species where appropriate.

These actions do involve human intervention, but they seek to heal rather than dominate creation.

Even in Singapore, extensive ecological restoration has helped recover habitats such as mangroves, coral reefs, and freshwater wetlands, demonstrating that thoughtful intervention can support biodiversity alongside urban development.

However, intervention should always be approached with humility. Ecosystems are extraordinarily complex, and well-intentioned actions can sometimes produce unintended consequences. Christians should therefore still value scientific expertise, ecological monitoring, and adaptive management as legitimate tools, but recognise that ultimately they are not the be all and end all - we should always commit any action into God’s hands through prayer and surrender.

So, to what extent should humans interfere? A biblical answer is that humans should intervene to the extent that our actions help creation flourish according to God's purposes.

This means:

• We should cultivate creation via the responsible production and consumption of food, managing resources, and meeting human needs.
• We should protect ecosystems from unnecessary harm.
• We should restore environments damaged by sin and human activity.
• We should exercise humility, recognising the limits of our knowledge and learning from ecological science.
• We should avoid exploitation, treating creation as God's possession rather than our own.

Ultimately, the question is not "Should humans interfere?" but "Do our actions reflect the character of the Creator?" By living as stewards rather than owners, we bear witness to God's wisdom, love, justice, and generosity. Christians are thus called to exercise our influence in ways that enable both people and the rest of creation to flourish for God's glory.
