Ecological and social collapses in both human and plant-based ecosystems are often triggered by a combination of interconnected stressors that overwhelm a system's capacity to adapt or recover. These triggers can be environmental, social, or a mix of both, and they frequently interact in complex, compounding ways across both types of ecosystems.
Common Triggers Across Human and Plant-Based Ecosystems
- Environmental Degradation and Resource Depletion: In plant-based ecosystems, persistent land clearing, deforestation, and habitat fragmentation disrupt biodiversity and ecosystem functionality, leading to collapse by diminishing habitats and reducing species' ability to survive [1][2]. Similarly, in human ecosystems, overexploitation of resources—such as deforestation for agriculture or overfishing—can precipitate societal collapse by undermining the ecological foundation that supports human livelihoods [1][3][4]. Jared Diamond's work highlights non-sustainable resource exploitation as a key cause of societal collapse, mirroring the habitat loss seen in natural ecosystems [3].
- Climate Change: Rising global temperatures and extreme weather events are significant drivers of collapse in both systems. In plant-based ecosystems, climate change affects vulnerable areas like coral reefs and polar ecosystems, with temperature increases threatening up to one in six species globally [4]. In human ecosystems, climate change exacerbates resource scarcity through megadroughts and other environmental shifts, pushing societies toward collapse by disrupting agriculture and water availability [5][6]. The Amazon rainforest, for instance, faces collapse risks from both deforestation and climate-induced resilience loss [2].
- Pollution and Chemical Imbalances: Pollution, including plastic waste in oceans and nitrogen deposition on land, directly harms biodiversity in plant-based ecosystems, leading to declines in plant and insect populations and ecosystem integrity [4]. In human ecosystems, pollution contributes to social collapse by degrading the environmental conditions necessary for health and economic stability, often compounding other stressors like climate change [6][4].
- Direct Exploitation and Overuse: Overfishing, logging, and other forms of direct exploitation threaten both ecosystems. In plant-based systems, unsustainable harvesting leads to biodiversity loss, with agriculture alone threatening over 85% of at-risk species [4]. In human systems, overexploitation—such as the collapse of the Atlantic northwest cod fishery—can trigger economic and social crises by removing critical resources [2][6].
Specific Triggers in Human Ecosystems
- Social and Political Factors: Human ecosystems face unique triggers like war, economic inequality, and political instability. Societal collapse often results from internal strife, corruption, or elite failure to adapt to crises, as seen in historical examples like the Western Roman Empire [3][7]. Population dynamics, such as youth bulges leading to unrest, also play a role in destabilizing societies [3].
- Global Polycrisis and Complex Interactions: Modern human societies are increasingly vulnerable to a "polycrisis" of interconnected crises—climate change, economic dysfunction, and social disintegration—that amplify each other through feedback loops. For instance, war in Ukraine has spiked energy prices, worsening inequality and fueling authoritarianism, which further erodes societal stability [6].
Specific Triggers in Plant-Based Ecosystems
- Invasive Species and Disease: Plant-based ecosystems are particularly susceptible to invasive species and diseases that disrupt native biodiversity and biotic interactions, often leading to rapid collapse [1][2]. Human activities frequently introduce these stressors, as seen with non-selective insecticides harming insect populations [4].
- Natural Disturbances with Human Amplification: While natural events like fires or floods can trigger collapse in plant-based systems, human actions often exacerbate these disturbances. For example, habitat fragmentation from roads in the Amazon creates a "fishbone" pattern that hinders recovery and increases extinction risks [2].
Synergistic Effects and Tipping Points
In both systems, collapse is rarely caused by a single factor but by multiple drivers interacting synergistically. Research shows that additional stressors can bring forward collapse dates significantly, with systems collapsing at lower thresholds of primary stress when secondary drivers or noise (random variability) are present [8]. For instance, in the Amazon, deforestation combined with climate change has reduced resilience since the early 2000s, pushing the ecosystem toward a critical tipping point [2]. Similarly, in human systems, compounding crises like environmental degradation and social inequality can overwhelm coping mechanisms, leading to rapid societal breakdown [6][7].
Conclusion
Triggers of ecological and social collapse in human and plant-based ecosystems overlap significantly, with environmental degradation, climate change, pollution, and overexploitation acting as shared stressors. Human systems face additional pressures from social, political, and economic factors, while plant-based systems are uniquely vulnerable to invasive species and amplified natural disturbances. The interaction of multiple drivers often accelerates collapse, underscoring the need to address these interconnected challenges to prevent tipping points in both systems.
