<< Objectives >>We know that single-use plastic is bad for our oceans, so we don't we stop using it? In fact, pro-environmental thoughts and behaviours are weakly linked, and we tend to be surprisingly inaccurate about the environmental impact of common behaviours. The Deep Network brings together marine researchers and adult educators to find what is important for us to know about human impact on the deep ocean, and suggest ways to educate adult learners so that they tend more towards and behaviour change.<< Implementation >>1) Start The Deep Network, whose common interest it is to share and/or develop quality educational material which could help move adult learners along a pathway from knowing more about seas and oceans, to acting to change their behaviour.2) Developing examples of existing inspiring practice in marine education and conservation, which show the different between just knowing, and acting on knowledge. 3) Collate everything online as a resource for future initatives.<< Results >>1) We will develop a profile of the informal adult learner in marine education/ conservation, to target what adult learners need to know about the role of our oceans in climate change.2) We will develop 15 examples of inspiring practice, to illustrate what makes specific adult learner profiles make pro-environmental changes to their behaviour 3) The Deep online platform and social media channels will curate and communicate marine information throughout.
