I find it's best to think of sustainability as a journey:it's better to take a small step forward than to wait around for the 'big jump'. When it comes to sustainability, we can’t be back seat drivers.
No one has seen a crisis like this before, so no one can tell you what to do with absolute certainty. There is no special box of experiences that has the magic answer, but we have had situations in the past that we can draw from, where we can transfer learnings and skills.
