Which of the following is NOT one of the types of efforts to save species?

Genetic modification techniques are not typically classified as standard efforts to save species in conservation practices. Captive-breeding programs, for instance, involve breeding species in controlled environments to increase their populations and ultimately reintroduce them into their natural habitats. Preserving genetic material is vital as it helps maintain genetic diversity, which is crucial for the adaptability and survival of species. Zoos, aquariums, parks, and gardens play a significant role in conservation by serving as sanctuaries for species and promoting public awareness about biodiversity and ecosystem health. While genetic modification can play a role in certain agricultural or biomedical contexts, it is not primarily focused on the immediate conservation of endangered species in the same manner as the other methods listed.
