Human beings possess remarkable psychological defence mechanisms. They allow us to survive trauma, loss, war, famine, and disaster. Without them, many of us would be overwhelmed by grief and anxiety. Yet these same mechanisms can become dangerous when they cause us to adapt to situations that should never become normal.
Across many parts of Ghana affected by illegal mining (galamsey), this is exactly what appears to be happening.
The Brain Protects Itself
Psychologists describe several related phenomena:
- Habituation repeated exposure to the same stimulus gradually reduces the emotional response.
- Desensitisation – repeated encounters with disturbing events make them seem less shocking.
- Psychic numbing – first described by psychiatrist Robert Jay Lifton and later explored by psychologist Paul Slovic, this is the gradual reduction in emotional responsiveness to large-scale human suffering.
- Compassion fatigue – emotional exhaustion experienced by people repeatedly exposed to others’ trauma, common among healthcare workers, emergency responders, and humanitarian staff.
These are not signs of cruelty. They are survival mechanisms. The human brain cannot remain permanently in a heightened state of alarm. Eventually, it reduces the intensity of its emotional response.
Unfortunately, the same mechanisms that protect individuals can destroy societies.
Living Among Environmental Catastrophe
Imagine growing up where rivers once provided drinking water, fishing, farming, recreation, and cultural identity.
Then, over several years:
- the rivers become brown toxic sludge,
- fish disappear,
- forests are stripped bare,
- farmland is buried beneath craters,
- mercury contaminates the food chain,
- excavators become part of the landscape,
- gunshots and mining machinery replace birdsong.
The first time these changes occur, people are horrified.
The hundredth time, they simply continue walking.
Not because they approve.
Because their brains have adapted.
The extraordinary has become ordinary.
Healthcare Workers Face a Similar Battle
The same psychological adaptation occurs among healthcare professionals.
Paediatricians, obstetricians, surgeons, nephrologists, neurologists, radiologists, laboratory scientists, nurses, midwives, and other clinicians repeatedly encounter devastating illnesses.
A single child born with severe congenital abnormalities can leave an entire medical team emotionally shaken.
But after seeing similar tragedies repeatedly, the emotional intensity inevitably diminishes.
This is not a loss of humanity.
It is the brain attempting to preserve its own functioning.
Without this adaptation, healthcare professionals could not continue working.
Yet there is a hidden danger.
When horrific cases become routine, society may begin accepting what should instead provoke urgent prevention.
The Invisible Victims
Mercury released during illegal gold extraction does not simply disappear.
In aquatic environments it can be transformed by microorganisms into methylmercury, a compound that bioaccumulates through the food chain and readily crosses both the placenta and the blood-brain-barrier. Prenatal and early-life exposure is associated with impaired neurodevelopment, reduced cognitive function, and other long-term neurological consequences. High levels of exposure can also damage the kidneys and nervous system.
The greatest victims are often invisible.
The unborn child.
The infant.
The toddler.
The child whose learning potential has been permanently reduced before taking a first step into a classroom.
These children rarely appear in headlines.
Their disabilities emerge gradually over years.
By then, the connection between environmental contamination and human suffering may no longer be obvious to the public.
Communities Begin Accepting the Unacceptable
One of the greatest dangers of psychic numbing is that people stop asking difficult questions.
Instead of asking:
- Why has this river died?
- Why are children becoming ill?
- Why is farmland disappearing?
- Why are communities dependent on expensive treated water?
People begin asking:
- When will someone bring another water tanker?
- Which hospital treats kidney disease?
- How do we live with poisoned rivers?
The focus shifts from prevention to adaptation.
From solving the problem to surviving it.
Institutions Are Not Immune
Psychic numbing affects institutions as much as individuals.
Government agencies.
Professional bodies.
Traditional authorities.
Religious organisations.
Civil society.
Media.
Universities.
Repeated exposure to environmental destruction without decisive action gradually lowers expectations.
Emergency becomes routine.
Routine becomes policy.
Silence becomes institutional culture.
Compassion Fatigue Among Environmental Advocates
Those fighting to protect forests and rivers are also vulnerable.
After years of documenting destruction, planting trees, educating communities, reporting illegal activities, writing petitions, and watching degradation continue, many advocates experience profound emotional exhaustion.
Some give up.
Some withdraw.
Some become cynical.
Others continue, but with depleted emotional reserves.
Compassion fatigue does not mean people care less.
It means they have cared intensely for too long without seeing sufficient change.
The Greatest Threat Is Normalisation
History teaches that societies rarely collapse overnight.
They deteriorate gradually.
One compromised institution.
One polluted river.
One destroyed forest.
One ignored warning.
One normalised tragedy at a time.
The greatest danger posed by galamsey may not be mercury alone.
Nor deforestation alone.
Nor polluted rivers alone.
It may be the gradual normalisation of all of them.
Once a society no longer reacts emotionally to its own destruction, meaningful intervention becomes increasingly difficult.
Breaking the Cycle
Psychic numbing can be reversed, but only through deliberate effort.
First, environmental destruction must be recognised as a public health emergency rather than merely an economic or mining issue.
Second, healthcare professionals should be encouraged to document and publish trends in diseases plausibly linked to environmental contamination, while carefully distinguishing observed associations from proven causation. Robust surveillance and research are essential.
Third, communities must continue seeing what is happening through photographs, satellite imagery, scientific data, and independent reporting. People cannot respond to what they no longer perceive.
Fourth, institutions must refuse to allow repeated exposure to become acceptance. The fact that a problem has existed for years does not make it less urgent.
Finally, every generation has a duty to remain morally sensitive. The brain may naturally dampen emotional responses to repeated trauma, but our ethical judgement must not follow the same path.
A Nation Must Never Become Comfortable With Its Own Destruction
The human brain is designed to protect us from unbearable emotional pain.
That is a gift.
But when psychological adaptation allows an entire nation to become comfortable watching its rivers die, its forests disappear, and its children bear preventable health burdens, that gift becomes a liability.
No society should mistake desensitisation for resilience.
Resilience is continuing to fight despite repeated setbacks.
Desensitisation is ceasing to recognise that there is still something worth fighting against.
A healthy nation must preserve not only its rivers and forests, but also its capacity to be shocked by their destruction. The day environmental devastation no longer troubles our conscience is the day we begin losing far more than our natural resources – we begin losing our humanity.
