The fundamental principle of conservation in science is the sustainable management of natural resources to ensure their availability for future generations. This principle emphasizes preserving biodiversity, ecosystems, and the services they provide, such as clean air, water, and soil fertility. Effective conservation strategies often involve restoring degraded habitats, protecting endangered species, and supporting sustainable practices among communities. By prioritizing conservation, we balance ecological needs with human development, promoting long-term sustainability and resilience in the face of environmental changes and challenges. Conservation science is thus critical for a healthy planet.
