Laws, international treaties, and species survival plans help shield endangered species. Meanwhile, conserving places, like biodiversity hotspots and protected parks, ensures the survival of entire ecosystems. Emerging fields like conservation genetics offer new perspectives, emphasizing the importance of protecting genetic diversity within ecosystems.
