Planetary health impairments and the myopia pandemic

The Rockefeller Foundation–Lancet Commission defines planetary health as: the achievement of the highest attainable standard of health, wellbeing, and equity worldwide through judicious attention to the human systems—political, economic, and social—that shape the future of humanity and the Earth's natural systems that define the safe environmental limits within which humanity can flourish. Put simply, planetary health is the health of human civilisation and the state of the natural systems on which it depends (Whitmee et al., 2015, p.1978). While this definition clearly demonstrates what is at stake for human systems if the state of natural systems is disrupted, putting emphasis first on humanity and the consequences for human civilisation of such disruption rather than on the equilibria of natural systems as the basis for planetary health, still places the analysis within an anthropocentric perspective. Inverting the emphasis to give priority to natural systems and humanity’s ecological niches and roles (together with all the other species that are currently present in the biosphere) within these systems establishes an ecocentric perspective. This enables clearer vision for understanding and addressing complex, interrelated causes of planetary health impairment such as climate change, biodiversity loss, urbanisation and its effects, damage to coastal areas, wetlands loss and damage, land degradation and desertification, forest clearance and land cover change, freshwater depletion and contamination, and numerous others, and the reciprocal interactions these have with human systems. A recurring myopic focus on climate change At this time of the year, as the dust settles on the latest edition of the annual COP meeting, particular attention is paid to climate change, both in terms of published scientific research and media coverage. The outcome of the recent COP 30 exemplifies various aspects of how myopia is a condition that afflicts humanity at two levels, both of which have complex multiple intersecting causes and effects. At the literal level, as a result of the rapid global rise of myopia, or near-sightedness, it is estimated that by 2050 more than half the world’s population will suffer from distance vision impairment (Lee et al., 2025). The result of this will be a massive increase in public health costs due to a need for treatment related to vision correction and the increased risk of numerous associated chronic pathologic visual changes. Moreover, although myopia and other eye conditions are the result of many interconnected phenomena, an increasing body of research shows how climate change is having an increasing negative impact on ocular health and that implementing strategies for mitigating climate change and its effects is imperative in order to counter this (Wong et al., 2024). At the same time, it is paradoxical that another significant cause of myopia is the lack of contact with nature, with all the benefits this brings, as humans young and old spend less time in the open air, thereby reducing the capacity of one of the principal organs through which they can acquaint themselves with their ecological surroundings (Clark et al., 2023). This leads to the increasing figurative myopia we currently suffer from as short-sightedness, having a limited capacity to foresee, an inability to assume a long-term perspective on the relationship between planetary crises and human trajectories. This may be because we are literally unequipped, biologically, historically, and politically, to foresee the long-term consequences that our actions now produce. For most of human history, limited impacts unfolded over short temporal and spatial scales. Only in the Anthropocene have our technologies generated massive lasting effects. This creates a structural mismatch between the unprecedented reach of our technological power and the limited temporal horizon of human cognition. At the same time, such myopia may also be an unwillingness to acknowledge the consequences of our actions, manifesting itself as a focus only on specific short-term interests while ignoring the catastrophic future consequences of triggering tipping points and the incalculable ensuing human and planetary health costs. At both levels myopia has long reached pandemic levels and shows few signs of slowing its exponential growth. However, while the consequences of myopia as a medical condition are serious and impact negatively on individuals and societies in numerous ways, the consequences of myopia as a psychological condition hamper our ability to understand the temporal and spatial dimensions of vital issues related to planetary health that are devastating for the entire biosphere as we know it. Moving from an anthropocentric to an ecocentric perspective is essential to be able to see things from a distance and act to avoid these consequences, reducing our impacts and the reach and intensity of technological systems whose effects exceed our capacity to anticipate or control them. As we look back on COP 30, we can only conclude that, despite overwhelming scientific evidence of future catastrophes, at international level there is still a total lack of a long‐term and planet-wide perspective in line with science and the necessary legislative and regulatory frameworks able to bring about action to change human trajectories and thereby mitigate and adapt behaviours and outcomes at environmental, economic, social and political levels. There is no explicit commitment to phasing out fossil fuels. Around 80 countries have not submitted any national climate plans to cut greenhouse gas emissions, while the others have submitted vague and inadequate plans. Given the gravity of our predicament, many scientists now project that the world is heading for at least 2.6° C of warming by 2100 (Climate Action Tracker, November, 2025), a scenario that can only mean global biotic disaster. Nevertheless, scientific research continues to increase our knowledge of specific issues such as climate change and the multiple questions and challenges posed concerning diverse aspects of mitigation and adaptation strategies. Moreover, scientific research must necessarily continue to render this knowledge available in the effort to counter the myopia pandemic that encompasses large numbers of the current human population, creating literal or wilful ignorance of what is at stake and thereby endangering the very existence of humanity itself. This issue of Visions for Sustainability is part of our ongoing endeavour to contribute to this, and, in particular, continue to provide a platform for research from the Global South so as to ensure a truly planetary vision. Climate change, economic growth and technological innovation In recent decades a vast body of research has studied the complex relationship between climate change, economic growth and technological innovation from multiple perspectives such as causes, impacts, mitigation and adaptation (Bousina et al., 2025), and also increasingly of the necessity of assuming a post-growth or degrowth perspective (Kallis et al., 2025). In “Are we on the right track for mitigating climate change?”, La et al. assesses global climate mitigation efforts in terms of what they consider both achievements and persistent shortcomings. Despite growth in renewable energy, international agreements, and technological innovation, as well as a carbon market, greenhouse gas emissions remain at record highs, and climate impacts continue to accelerate. The ongoing hegemonic growth-oriented paradigm and belief in technological solutions reinforce existing exploitation paradigms rather than transforming them. They propose transitioning from an eco-deficit to an eco-surplus culture, where ecological restoration and protection are fundamental for socio-economic well-being and development. In “Towards an eco-surplus culture. From market failures to vulnerabilities and logical flaws of ‘artificial’ environmental protection systems” Vuong et al. continue their analysis of mainstream economics’ growth-oriented and technology-centric paradigms. They show how these perpetuate the illusion that continuous economic growth is compatible with environmental protection through prioritizing investment in technological solutions. As an alternative paradigm they propose the adoption of the semiconducting principle of monetary and environmental value exchange. This requires the cultivation of Nature Quotient (NQ) across society and a broader socio-cultural shift toward an eco-surplus culture, in which environmental protection, restoration, and regeneration are foundational preconditions for long-term economic resilience, political stability, and social well-being. There is an intimate connection between climate change and rural health and resilience. By 2050, an estimated 70% of the human population is expected to live in urban areas. If an increasing majority of people becomes urban dwellers, they still totally depend on those that live in rural areas and the rural ecologies they are a part of, many of which are particularly vulnerable and at risk. In “Climate resilience to floods on rural roads in Cambodia” Ly & Yeom examine the vulnerability of rural roads in Cambodia to flooding and ways of enhancing climate resilience through spatial and hydrological analysis. The study utilizes Geographic Information Systems (GIS) and a Rational Method to assess flood risks and identify infrastructure vulnerabilities in Siem Reap Province. To mitigate the risks of the growing impact of climate variability, they recommend infrastructure improvements such as enhanced drainage systems, road elevation, and the use of permeable materials. They argue that the results of their sudy offer valuable insights for policymakers and engineers to prioritize investments and develop climate-resilient infrastructure strategies and foster sustainable rural development.
