The lower right quadrant image is perhaps the most obvious and straightforward. Here is a picture of Circular Quay in Sydney. It depicts the line between the natural world (represented by the blue sea and sky) and the human infrastructure that seems to dominate both. To heighten the contrast, a white tern from Lord Howe Island is hovering over the water and seems to be looking back at the newly-emergent human world. The two works behind this image are Wilson’s The Future of Life and the Meadows’ Limits to Growth – the 30 Year Update. Works of this kind are crucial for appreciating the current imbalances between the human world and the natural world upon which all people, all cultures and all human economies are entirely dependent.
