There’s lots of great thinking about relational aspects on the environment. One example that we came across recently and like is Olaf Brugman on “From Sustainability of Things to Sustainability of Relationships”.
He argues that sustainable development is shaped not only by the directly visible artefacts that we produce such as fuel-efficient cars, sustainable buildings or low carbon agriculture practices. It is much more shaped by invisible factors embedded in legislation and institutions. The sustainable development of relationships between consumers, business and politics creates a context in which different solutions are possible and blocks of some less sustainable paths.
