Designing a Sustainable World. The critical issue – for people, organizations, and governments alike- is knowing where we want to be. The imaginary, an alternative cultural vision, is vital in shaping expectations and driving transformational change. Shared visions act as forces of innovation, and what designers can do- what we all can do- is imagine some situation or condition that does not yet exist but describe it in sufficient detail that it appears to be a desirable new version of the real world.
