The rapidly increasing human pressure on the biosphere is pushing biodiversity into the sixth mass extinction event in the history of life on Earth. The organisms being exterminated are integral working parts of our planet's life support system, and their loss is permanent. Like climate change, this irreversible loss has potentially devastating consequences for humanity. As we come to recognise the many ways in which we depend on nature, this can pave the way for a new ethic that acknowledges the importance of co-existence between humans and other species. Biological Extinction features chapters contributed by leading thinkers in diverse fields of knowledge and practice, including biology, economics, geology, archaeology, demography, architecture and intermediate technology. Drawing on examples from various socio-ecological systems, the book offers new perspectives on the urgent issue of biological extinction, proposing novel solutions to the problems that we face.
