Human activities, such as deforestation, pollution, and urban development, are major contributors to biodiversity loss. These actions lead to habitat destruction, fragmentation, and degradation, which directly threaten various species' survival. As ecosystems are altered, many species struggle to adapt, resulting in endangerment or extinction. Additionally, the introduction of invasive species often displaces native organisms, further exacerbating the biodiversity crisis. Understanding this relationship emphasizes the need for sustainable practices to preserve ecosystem integrity and maintain global biodiversity.
