When asked about the impact of sustainability in food, and the message he hopes to communicate through The Great Farm Feast, Luke says, "‘Sustainable’ is the bare minimum, it has to go beyond that – to realise that there’s so many components that go into getting food onto the plate; externalised costs, be that environmental or social, that need to be considered as part of that equation.” This meal is a great reminder that sustainability comprises not just environmental impact, but social and governance (that is, "ESG") too.
