These sources explore the complex nature of ecological systems, emphasising that human observation and scaling are what define our understanding of nature rather than an objective reality. The authors critique conventional hierarchical models, arguing that they are often too rigid to account for the fluid, messy exchanges of material in real ecosystems. By distinguishing between structural complicatedness and organisational complexity, the texts suggest that social and ecological collapse can result from the diminishing returns of solving problems through increased infrastructure. They propose a “supply-side” approach to sustainability that prioritises managing the underlying ecosystem functions rather than just the resources they provide. Scientific inquiry is presented as a narrative process, where choosing the correct spatial and temporal scale is essential for creating predictive models that reflect biological truth. Ultimately, the works advocate for a unified ecology that integrates various criteria—from populations to biomes—to better manage a world defined by interconnectedness and surprise.
