Final answer:
Preserving species is important as they can provide useful genes for improving existing organisms and for valuable medical research.
Step-by-step explanation:
Preserving species is important because they can serve as a potential source of useful genes. These genes can be utilized to improve the characteristics and traits of existing crops, livestock, and other organisms. For example, genes from certain wild plants can be transferred to cultivated crops to enhance their resistance to pests, diseases, and environmental stresses. Similarly, genes from rare animal species may be valuable for medical research and the development of new drugs.
