This paper cautiously ponders the offerings of transhumanism. We begin the paper by introducing the transhumanist movement and related transdisciplinary thinking before giving space to the emergence of critical disability studies. We argue that the latter field has the potential to ground a critical and reflexive analysis of transhumanism– not least through a consideration of the contributions of posthuman and green disability studies. Drawing on these two perspectives, two specific areas of transhuman contemplation are offered. First, we consider (in the section titled, ‘The Ban on Straws: Disability prosthetics and the complication of eco-politics’) the relationship between disability advocacy politics and the potential ableism present in popular eco-political discourse. Second, we explore mainstreaming assistive technologies and e-waste collateral. These analytical thematics highlight the complexities of a critical transhuman disability studies, not least, in relation to the clash of disability and green politics. We conclude the paper with some considerations for future theory and research that trouble an uncritical acceptance of transhumanism in the area of critical disability studies.
