I haven't read her book, but it has been recommended to me. One of the reasons I asked is because I'm also not sure if I get it. What I think she wants to say is that this: ...is the big problem of our times, and that we need to curb growth so we can sustain the planet, but not destroy it so that we have our basic needs and rights met. E.g. have an economy that can provide everyone with clean drinking water, but where we don't ship mineral water across the globe because we can. I thought it was interesting because unlike many discussions about the ails of capitalism, it seems to me a first step towards outlining an economically viable solution."Anyone who thinks that you can have infinite growth on a planet with finite resources is either a madman or an economist." - Sir David Attenborough
That was Ken Boulding, actually. Now that it's been misattributed via a Reddit thread, no one will ever know the truth ever again.
