ABSTRACT
This chapter presents a minimal definition of environmental ethics and climate ethics, despite both containing many different orientations. The lack of environmental ethical concern in climate ethics and policy may be understandable, as climate change, in a sense, trumps biodiversity loss in terms of the scale of harms that will result. Climate ethics is consistent with substantial reductions in biodiversity if required to reduce the risks of dangerous climate change, as long as additional factors are also warranted, such as ecosystems resilient enough to provide anthropocentric utilities. Many ambitious, large-scale efforts will be required to reduce the risks of dangerous climate change while also slowing the sixth mass extinction. Technological efficiency would most likely increase pressures on both habitats and the atmosphere and thus be inconsistent with both climate and environmental ethics. Lastly, limiting consumption would be consistent with both climate and environmental ethics.
