[2] This topic has been approached from various angles, including its connections with the causation of harm to animals, environmental degradation, climate change, and the emergence and spread of zoonoses.
[3] More recent work has also considered the ethics of in-vitro flesh and the idea of creating animals with decreased pain sensitivity, where Deckers chaired a conference on these themes, funded by the Wellcome Trust.
[7] Deckers has analysed debate in Westminster Parliament around the use of embryos for stem cell research and cloning as well as the law on abortion in Great Britain, and argued for legal reform.
[12] More recent work reflects on the meaning and the moral significance or otherwise of the (un)natural, where Deckers argues, inspired by Alfred North Whitehead’s teleological understanding of natural entities, that the concept of the unnatural carries both meaning and moral significance in discussions of genetic engineering.
At the same time, his (ontological) understanding of the world is critical of Whitehead's thought by rejecting the view that the universe as a whole is a teleological entity.
[13][14] Deckers also developed a contextualised case in human genetics as a teaching resource for Advance Higher Education.
