Ecological collapse refers to a sudden and rapid decline in the population, health or productivity of an ecosystem. This can be caused by various factors such as habitat destruction, pollution, overexploitation of resources, climate change, introduction of invasive species, disease outbreaks or natural disasters. The consequences of ecological collapse can be severe and long-lasting, affecting not only the affected ecosystem but also the surrounding environment and human communities that depend on it for their livelihoods. Efforts to prevent or mitigate ecological collapse often involve conservation measures, sustainable resource management practices, habitat restoration and protection of endangered species.
