‘I could fly to New York and back every day for seven years and still not leave a carbon footprint as big as if I have a child. Ten thousand tonnes of CO2. That’s the weight of the Eiffel Tower. I’d be giving birth to the Eiffel Tower.’

In a time of global anxiety, terrorism, erratic weather and political unrest, a young couple want a child but are running out of time. If they over think it, they'll never do it. But if they rush, it could be a disaster.

They want to have a child for the right reasons. Except, what exactly are the right reasons? And what will be the first to destruct - the planet or the relationship?

Part of The Roundabout Season

In a unique collaboration, Paines Plough and Sheffield Theatres are building a 150-seat portable in-the-round auditorium.

The first Roundabout Season will see the world premières of three plays – by Nick Payne, Duncan Macmillan and Penelope Skinner - performed by an ensemble of four actors. All three plays will open at Sheffield Theatres before touring nationwide, in rep, in Spring 2012.

LUNGS is produced in rolling world première with The Studio Theatre, Washington DC, in Autumn 2011.
