It has become something of a mantra within the sustainability movement that innovations in technology will save the world and all of us in it, but we tend to forget that technology played a big part in getting ourselves into this mess in the first place. In a manifesto released back in August, author Richard Heinberg, who is also the Senior Fellow-in-Residence of the US-Based Post Carbon Institute, explains why technology, which is widely heralded as our saviour, is not the secret sauce to solve all our environmental troubles. He joins us to discuss his arguments in the manifesto which is titled, "There’s No App for That: Technology and Morality in the Age of Climate Change, Overpopulation, and Biodiversity Loss."
