I look at species like the Wrens finding a way despite their isolationous tendencies at non-cold periods of the year, that they are finding ways to work together to avert a potential killing crisis which is the cold. In that I see an extraordinary metaphor for what we’re currently facing when it comes to the great environmental crises of the planet - that we tend to live individualistic lives within a capitalist, economic system that encourages individual behaviour and thinking, and yet we really need to find ways of locating the collective and communal admits that if we’re to challenge many of these issues".
