Terrible events — wars, ecological collapse, climate destabilisation — often feel like they erupt out of chaos. But when you trace them back, you find something more mundane and more uncomfortable: human decisions. Some are made out of fear, some out of short‑term thinking, and some out of outright greed. Together, they shape the world we live in.
This article explores how greed and poor choices contribute to three major global crises: war, global warming, and biodiversity loss — and why understanding these drivers matters for building a better future.
⚔️ 1. War: When Greed Meets Fear
Modern research shows a strong link between environmental vulnerability and conflict, especially where resources are scarce or degraded. Environmental stress can increase the likelihood of conflict, particularly in regions already facing political instability . Biodiversity loss and environmental degradation can also interact with social tensions, influencing pathways to conflict ScienceDirectScienceDirect.

But environmental stress alone doesn’t cause war. Human choices do.
Greed’s role
- Control of oil, minerals, land, or strategic territory
- Expansion of political or economic influence
- Capture of wealth by elites at the expense of the population
Poor choices
- Leaders escalating tensions instead of negotiating
- Nations prioritising military spending over diplomacy
- Short-term political gains trumping long-term stability
Greed creates incentives for conflict; poor choices remove the brakes.
🌡️ 2. Global Warming: A Crisis Built on Short-Term Thinking
Climate change is the most predictable disaster humanity has ever created — and one of the most preventable.
Greed’s role
- Fossil fuel industries protecting profits
- Governments prioritising economic growth over sustainability
- Corporations externalising environmental costs
Poor choices
- Delaying climate action for decades despite clear warnings
- Designing cities around cars instead of people
- Treating nature as infinite rather than fragile
Climate change is not an accident. It is the cumulative result of billions of decisions made without considering long-term consequences.
🐾 3. Biodiversity Loss: The Silent Catastrophe
Biodiversity loss is less visible than war or climate change, but it is just as dangerous. Research shows that environmental degradation can contribute to social instability and conflict, creating feedback loops between ecological decline and human insecurity .
Greed’s role
- Overexploitation of forests, oceans, and wildlife
- Industrial agriculture prioritising yield over ecosystems
- Illegal wildlife trade driven by profit
Poor choices
- Destroying habitats for short-term development
- Ignoring ecological warnings
- Failing to protect species until they are nearly gone
Biodiversity loss is a slow-burning tragedy caused by treating nature as expendable.
🔍 So… Is Greed the Root Cause? Or Poor Choices?
Greed is a powerful accelerant. Poor choices are the spark.
But the deeper truth is this:
Terrible things happen when societies reward short-term gain over long-term wellbeing.
Greed is simply one expression of that imbalance. Poor choices are another. Together, they create systems where destructive outcomes become almost inevitable.
🌱 What Would Better Choices Look Like?
1. Long-term thinking
Policies that look beyond election cycles and profit margins.
2. Shared responsibility
Recognising that environmental and social stability are collective goods.
3. Valuing nature
Treating ecosystems as assets, not obstacles.
4. Reducing inequality
Because unequal societies are more vulnerable to conflict and ecological harm.
5. Transparent governance
Greed thrives in secrecy; accountability reduces its power.
✨ A More Hopeful Ending
The world is not doomed to repeat its mistakes. Greed and poor choices are human behaviours — and humans can change. We can design systems that reward sustainability, cooperation, and long-term thinking. We can choose leaders who value peace over profit. We can build economies that regenerate rather than extract.
Terrible things happen when we fail to act wisely. Better things happen when we decide to.
