British artist James Lake first began to use cardboard in his work after losing his leg to bone cancer 20 years ago, finding strength and versatility in this unlikely, yet readily available material. In a new video from Rajapack, Lake recalls his story and shows a bit of his process. Lake used Earth Overshoot Day as inspiration for a sculpture that "shows the size the earth would need to be to support the speed we are consuming the Earth’s resources. At the centre of the sculpture sits the Earth, and encasing half of it is a shell 1.7 times larger."
