Where is the best place to start a constructive conversation about topics in sustainable design and manufacturing within the Nature community?
Thank you for the question, it might help us find many new resources! I would be very interested in what the rest of the community will have to say about it.
Most online discussions that I have seen on topics related to sustainability happen on researchgate, although they usually focus on explaining or clarifying established concepts to new research field members.
(Here is an example:
Otherwise, it seems that most of the discussion is not online but, naturally, on conferences like AGU for all climate change-related science( https://fallmeeting.agu.org/2017/), or more topical discussions like in ASABE on agriculture (http://www.asabemeetings.org) or ECO-BIO on bioeconomy (https://www.elsevier.com/events/conferences/eco-bio).
With best wishes,
