Swedish artist Johanna Mårtensson created this installation depicting a cityscape made of bread in 2009, and photographed it as it decayed, creating a series of pictures representing the destiny of all human folly come the day that we make ourselves extinct and vanish from the face of the Earth:
I was inspired by an article about how well the earth would do without us. Within 500 years all buildings would be half fallen or fallen, perfect homes for animals and plants. The forrest would soon grow in cities. After hand buildings as well as pollutions would be taken care of by bacterias and micro-organisms. An ufo that came here in a couple of of hundred thousand years would not see many signs of that a gang of primates ones thought that they where the lords of the planet.
