The primary cause of extinction is often attributed to habitat destruction, primarily driven by human activities such as deforestation, urbanization, and agricultural expansion. These processes lead to the loss of biodiversity, making it difficult for species to survive and reproduce. Other significant factors include climate change, poaching, pollution, and invasive species that compete with native flora and fauna. The decline of species can disrupt ecosystems, leading to cascading effects that threaten the resilience of entire habitats, thus underscoring the urgent need for conservation measures.
