The document discusses cloning extinct animals and provides arguments for and against the practice. It argues that cloning extinct species could allow scientists to study how they became extinct, help preserve biodiversity, and potentially use extinct animals for food or scientific research if de-extinction is done carefully and the animals' habitats are protected. However, others worry that attempts to reverse extinction could disrupt nature and encourage the view that species loss is not permanent. The conclusion is that while some limited de-extinction may be acceptable, efforts are needed to primarily preserve existing biodiversity and ecosystems.
