This important collection focuses on the nature and importance of biodiversity. Many controversies currently surround biodiversity and a few of them are examined here: What is worthy of protection or restoration, and what is the acceptable level of costs? Is it permissible to kill sentient animals to promote native populations? Can species be reintroduced if they have disappeared a long time ago? How should the responsibilities for biodiversity be shared?
