  In addition to work in environmental ethics, Sylvan wrote on other ethical issues including arguments for moral obligations to future generations (cf. Routley and Routley 1978, Sylvan and Plumwood 1991), and the ethics of energy choice (Routley and Routley 1979c). The argument offered in the latter paper against nuclear power centres on the (anthropocentric but nonetheless, in Sylvan’s view, salient) claim that bequeathing toxic nuclear waste to future generations constitutes an ethically unacceptable shift of costs onto others. And a similar argument was mounted against conspicuous consumption of fossil fuels from what Sylvan and Plumwood then referred to as “atmosphere heating” (Routley and Routley 1979c, §3). Theirs appear to be amongst the earliest philosophical discussions focussing on the ethics of climate change. And it is not just the claimed immorality following from the consequences of climate change to future humans, though that is given weight; from a deep green perspective, the claimed erosion of value outstrips mere anthropocentric concerns and needs to take into account non-human nature, where the resultant erosion of intrinsic value is taken to loom large.
