I had a discussion recently with futurist colleague Wendy Schultz about defining the change that happened in Europe and America in the late 18th century. It was the enlightenment, certainly, through which a whole host of new political views about public voice and the independent integrity of the individual emerged into the mainstream, even if took another 150 years, or even 200, to work themselves out. And at the same time it was the beginning of the age of extraction, when humankind started to use the stored resources of the planet at scale for their profit and endeavour. Both of these ideas are still the dominant frames of our public discourse, certainly in the richer world, and shape (almost completely) competing arguments about sustainability. So I was lucky – even privileged – this week to hear the Canadian landscape photographer Ed Burtynsky talk about his work at a private event organised by Arup in London.
