Professor Walker thinks there is only one way to maintain a human society that can respond to unexpected change. That way is to develop a system with a high capacity for restoration, which means a society with high resilience.
Despite this, people nowadays tend to avoid thinking about change. For example, some people avoid facing the fact of climate change because of the high cost of responding to it, preferring simply to continue the existing ways. Professor Walker considers this attitude to be a problem.
Change may sometimes cause pain, but Professor Walker thinks it is necessary to accept such change to respond to difficult problems.
For humans to survive, it is necessary that we adapt to changes and increase our social-ecological resilience. Achieving this will ensure a desirable future.
