The primary influence of human intervention on natural ecosystems is the disruption of ecological balance. Activities such as deforestation, pollution, and urbanization can lead to habitat destruction and fragmentation, altering the dynamics of species interactions. Human actions often introduce invasive species, which can outcompete native ones, leading to biodiversity loss. Additionally, practices like overfishing and industrial agriculture negatively impact ecosystem services, which are crucial for maintaining environmental health. This intervention calls for sustainable practices to restore and protect these ecosystems.
