The impact of resource overexploitation on biodiversity is profound, leading to population declines and species extinctions. Unsustainable harvesting of wildlife, fisheries, and timber diminishes ecosystem integrity and destabilizes food webs. Overexploitation threatens not only individual species but also the broader ecological balance, affecting genetic diversity and resilience. Addressing these issues requires implementing sustainable resource management practices and enforcing regulations to protect species and their habitats, ensuring the long-term health of ecosystems and biological diversity.
