This is an excellent novel (at least partially autobiographical) following the life of a writer as he gives up his essay on Kafka to work as a road sweeper in Prague in Cummunist Czechslovakia. From an environmental point of view, the garbage is the most interesting element of the novel. Although the novel doesn't take a specifically environmental stance the fact is it deals with a vastly important environmental issue, how we deal with our rubbish.
The narrator's work as a garbage collector stimulates his meditations on how people were treated as garbage in the ghettos and concentration camps in Nazi Europe which he had lived through as a child. This stimulates the reader to think about how our throwaway society may affect our attitudes to our fellow human beings and in fact other living creatures we share our planet with.
The whole narrative is fairly meandering and moves seamlessly through different time periods and different themes. Kafka is referred to a lot, he's obviously a great influence on the narrator, despite him having given up on his essay!
