To deal with an uncertain future, global ethics as an academic endeavour might consider a common value we all share, such as sustainability, which acts as an all-encompassing term to indicate our future direction. Technologies of the near future that are currently in development hold problems and promise, and are clear subjects for the ethics of sustainability at a global level. Autonomous military combat robots, insects as food (entomophagy) and in vitro synthetically grown meat are significant cases. Such robots might in fact serve injustice and work against sustainability, and such novel food technologies may hold hope for promoting sustainability and global justice. © 2014 © 2014 Taylor &amp
