The cover was designed by the author and developed by Shwetha VC. The central figure of the cover symbolically represents planet Earth, the constituent artificially developed human societies, and the effects of such human constructs on the environment of the planet. The right half of the figure represents a scenario in which our societies are polluted due to unsustainable manufacturing practices. The left half of the figure represents a scenario in which, our societies are environmentally sustainable and prosperous. The wind-mill and the service technicians represent product-service systems and their potential to support the transition towards an environmentally sustainable society. The human face fused with the planet symbolically suggests that the key to unlock the doors to either scenario, lies with our ability to think and design our societies.
