The ecological lens is a modelling language for evolving ecosystems. It uses the four categories of the SECI knowledge creation spiral (socialisation, externalisation, combination, internalisation) to connect the human lens and the evolutionary lens via the activity of play and a critical perspective/motivation. The ecological lens catalyses diversity within the living world from an ecological perspective.

A complete picture of the ecological lens contains 22 categories: the 13 categories of the human lens, the 5 categories of the evolutionary lens, and the 4 categories of the SECI knowledge creation spiral.

A more precise model of the links between the human lens and the evolutionary lens contains multiple links to and from specific elements in the evolutionary lens.
