Global Health Under Siege: How War, Climate Disasters, and Neglect Are Deepening the Divide Between the Haves and Have-Nots

The illusion of peace has shattered. A historic agreement to end a 100-day war that shut the Strait of Hormuz—through which one-fifth of the world’s oil passes—collapsed almost immediately when Israeli Prime Minister Benjamin Netanyahu rejected the deal [1]. In response, Iran’s Revolutionary Guard shut the strait again, the United States launched military strikes, and Iran struck US bases in Kuwait and Bahrain, leaving 11,000 crew members trapped on ships [1]. A separate US-brokered ceasefire between Lebanon and Israel is also unraveling, leaving over 100,000 displaced residents facing destroyed villages with no water, electricity, or roads [1].

The human cost of these converging conflicts is staggering, particularly for the most vulnerable. In Gaza, after 1,000 days of war, more than 38,000 women and girls have been killed, according to the United Nations women’s agency, UN Women [2]. At least 21,000 children have been killed, according to the aid agency Save the Children [1]. A United Nations commission of inquiry has accused Israeli security forces of deliberately targeting and killing Palestinian children, describing the actions as "genocide," "crimes against humanity," and "war crimes" [1]. The health system has completely collapsed; more than 1,500 sick and wounded Gazans have died waiting for medical treatment abroad, according to the director of Gaza’s largest hospital [3]. The war has also plunged people with disabilities into a deeper crisis, with the collapse of rehabilitation services cutting them off from basic aid, including wheelchairs and hearing aids [1].

In Sudan, the United Nations Security Council has warned of an "imminent risk of mass atrocities" in the city of El-Obeid, where paramilitary forces are surrounding approximately 500,000 civilians [4]. The number of people forced to flee their homes worldwide has hit a record 120 million [1]. More than 25,000 migrants have fled South Africa after a wave of anti-foreigner violence left at least four people dead [1].

Beyond the battlefields, the climate emergency is accelerating with terrifying speed—and it is the poor who are dying first. A record-breaking heatwave in France caused approximately 1,000 excess deaths in one week, prompting the Prime Minister to call an emergency crisis meeting [1]. Scientists estimate that Europe’s June heatwave killed around 20,000 people across the continent [5]. Across Europe, extreme heat is now killing more than 100,000 people every year, but most homes still have no air conditioning, leaving the elderly, the sick, and the poor to die indoors [1]. The world’s oceans have never been this hot, hitting a record 20.86 degrees Celsius, as scientists warn we are entering "unexplored territory" [1]. In Indonesia, the government is bracing for a severe drought that could last up to 11 months, as the El Niño weather pattern threatens to trigger both water shortages and livestock disease outbreaks across the archipelago [6].

Even as these disasters unfold, the global economic system continues to prioritize profit over human welfare. Turkey’s annual inflation rate has surged to 32%, locking pension increases at just 13.5% and pushing the minimum wage below the cost of basic food for a family of four [7]. Over 12.6 million people are effectively unemployed, forcing two out of three retirees back into the job market [7]. In Algeria, parliamentary elections saw just 20% of eligible voters cast ballots—the lowest turnout in the country’s history—as citizens focused on the rising cost of living rather than politics [8].

Yet amid the destruction, small signs of change offer a glimmer of hope. In Nigeria, Enugu State Governor Peter Mbah has declared that clean water is a fundamental right and launched a major push for universal access, while new data shows his healthcare overhaul has already boosted clinic visits by 80 percent [9]. Scientists have created the first global map of seagrass ecosystems, revealing these underwater meadows absorb carbon up to 35 times faster than tropical rainforests [1]. Indonesia has launched an aggressive plan to restore 12.3 million hectares of damaged forests, peatlands, and mangroves by 2030 [1]. But these efforts are dwarfed by the scale of the crisis. The common thread running through these disasters is a global system that spends more on weapons than on health, leaving the world’s poorest to bear the costs in hunger, displacement, and death.
