Why a species no longer exists?

A species may no longer exist due to various factors, including habitat loss, climate change, overexploitation, and invasive species that disrupt their ecosystems. Human activities, such as deforestation and pollution, can accelerate these threats. Additionally, natural events like diseases or changes in food availability can contribute to their decline. Collectively, these pressures can lead to a species' extinction when it can no longer adapt or survive in its environment.
