Waste-island Ireland and the 'necklace of incineration'

A "roaring black market in garbage collection" has produced this new landscape – or, landscape engineering through waste-management practices. It's a new surface of the earth made of industrial debris ("twisted wrecks of unidentifiable junked machines").
As the sea encroaches and the artificial terrain of human rubbish is revealed – the new outer edge of the Irish island – we find not bedrock, not archaeological sites, not even *terra firma*, but a bunch of old computers and kitchen waste.
