What will the world be like afterwards? What can we do to make the world more liveable afterwards? What can we learn from this extreme global experience? How can we equip ourselves to defeat the pandemic and prevent anything like this ever happening again? What can we leave behind? How can we recover without going backwards? How can we reimagine our lives, our households, our organisations, and our living environments: the cities, infrastructure and communications? How can we reconcile humanity with nature? And how can we distribute the achievements of science and technology in a more just and more efficient way across the world, between the generations and within our societies and communities.
