The primary focus of conservation biology is to understand and preserve biodiversity and the ecosystems that support it. This interdisciplinary science seeks to address the causes and consequences of species extinction, habitat loss, and ecosystem degradation. By integrating principles from ecology, genetics, social sciences, and economics, conservation biology informs strategies to protect endangered species and restore ecosystems. It emphasizes sustainable management practices and policies that balance human needs with the preservation of natural environments, ensuring a healthy planet for future generations.
