The previous chapter has presented Vision 2050 as a road map to a sustainable earth. In earlier chapters, we have tried to demonstrate that this vision can become a reality only if scientists, industry leaders, and policy-makers around the globe work together to develop, implement, and share technologies for sustainability. However, this vision also requires the support and participation of the general public. For example, it would be impossible to make new products from waste materials without the cooperation of local citizens in recycling and without the creation of an infrastructure for separating and collecting garbage. In this chapter, let’s consider the problems that arise at the point of contact between technology and society and how we can address these problems.
