Congratulations for making serious and important decisions about your use of climate crisis terminology (18 May). With one big exception: the use of “wildlife” rather than “biodiversity”. “Wildlife” used to mean “animals” (far from all living diversity), and has morphed into some sort of general term for things in nature reserves. It is those cute things Sir David watches from behind trees. In contrast, biodiversity is straightforward. It is the diversity of life – all the things we need to look after, from elephants to bacteria, and from ecosystems to molecular DNA diversity.
