Interconnected catastrophic threats jeopardizing global health, say researchers
More than a dozen “interconnected catastrophic threats” are projected to pose significant risks to global health and well-being throughout the 21st century, with some even suggesting the potential for extinction. Targeted actions from world leaders could mitigate these worst-case scenarios, reports BritPanorama.
A commission comprising 35 leaders from various industries utilized data from the Institute for Health Metrics and Evaluation’s Global Burden of Disease study to estimate the loss of good health years for the global population due to sickness, disability, and premature mortality stemming from multiple threats.
Their findings, published in the journal The Lancet, identify 17 threats that present the most significant dangers; however, the report highlights the potential for realistic interventions to counter these risks. The threats encompass a range of health conditions and behaviors, including obesity, high blood pressure, smoking, and mental health issues, alongside economic instability, environmental changes, technology risks, and conflict.
If current trends persist, these threats could lead to tens of billions of years of lost health. “The striking finding is not only the scale of these threats, but that humanity still has the agency to act,” said Dr. Christopher Murray, co-chair of the commission and director of the University of Washington’s Institute for Health Metrics and Evaluation.
Dr. Murray added, “Across all 17 catastrophic threats, the decisions made by leaders today will shape the health and well-being of the next generation. But delaying action will only serve to shift and increase the costs into the future.”
The commission has identified two threats that pose a risk of extinction: nuclear conflict and the malicious use of artificial intelligence (AI). Recently, an initial public offering for the AI company Anthropic indicated that its models could pose catastrophic or existential risks to humanity, with industry professionals warning of AI’s potential to exterminate the human species, possibly within the decade.
The report revealed a “wide divergence” among forecasters estimating the risk of AI-related disasters. Nonetheless, the commissioners highlight the emergence of powerful AI systems as an illustration of how swiftly assumptions about stability can be disrupted, echoing evidence from other recent global shocks, including the Covid-19 pandemic, the ongoing Ebola outbreak in Africa, and escalating climate impacts.
Projected losses in healthy life years due to malicious AI could amount to approximately 10.4 billion years globally by 2100, comparable to risks posed by pandemics and obesity. However, as “no malicious AI event of a truly global magnitude” has yet occurred, estimates concerning AI risks remain largely theoretical, whereas those associated with obesity are supported by more empirical data.
Data indicates that overweight and obesity trends are rising across all countries, with projections suggesting that 60% of adults and one-third of children could be classified as obese by 2050. Obesity correlates with numerous adverse health outcomes, linked to increased caloric intake and decreased physical activity, prompting the commission to forecast a “major global impact of this cluster of behavioral risks.”
The focus of the new commission extends beyond ranking threats; it aims to catalyze international, regional, and national actions to protect and enhance future health and humanity. Dr. Natalia Kanem, former executive director of the United Nations Population Fund and co-chair of the commission, emphasized that recent global events illustrate the rapid transition from stability to crisis and the high costs of delays in interventions.
Kanem noted, “Governments and communities must act decisively starting today, to protect health and build a fairer, more peaceful and more secure future for the coming generations.” Trust emerges as a key component for effective intervention, positing that it is a “stabilising force, enabling societies to anticipate, mitigate, and adapt,” while distrust can exacerbate potential harms.
In addition to trust, the report identifies several other factors integral to shaping societal responses to future threats. These include collaborative global leadership, resilient food systems, and efforts towards fostering equitable societies.
Ultimately, the report concludes that achieving meaningful progress necessitates not only technical solutions but also robust societal and institutional frameworks that prioritize collaboration and accountability.
