What would you recommend? Books on ecotheology

I frequently get asked for recommendations of which book(s) to read on ecotheology.* If Christians want to start thinking more seriously about God amidst our ecological crises, where should they begin?
I use ecotheology fairly broadly to mean the study of theology from an ecological perspective, or the study of ecology from a theological perspective, rather than a particular movement within those fields.

I have a few ideas, though am very open to finding new texts as I've only read a tiny fraction of what is out there. Obviously, different books will suit slightly different purposes. Some might do better at introducing the major intellectual debates, some relate ecology to major theological themes and scriptural passages, some aim to persuade suspicious Christians of why we might bother with ecological matters, some give better grounding in the science and ethics of the key threats and challenges, some give a greater sense of direction and application regarding what we can do in response to them. All are needed for their various purposes.
