On this episode of The Plasticology Project Podcast I speak with Sarah-Jo Lobwein. Sarah-Jo has been a plastic pollution campaigner in Sydney’s Sutherland Shire for many years. Sarah-Jo was one of the founders of SO Shire – Sustainable Organisations of the Sutherland Shire. Marine biology is a passion for Sarah-Jo and this led to a desire to help improve the coastal ecosystems off eastern Australia. As an environmental educator and plastic pollution warrior, Sarah-Jo has led hundreds of beach clean-ups, and regularly provides workshops for schools and community groups. In addition to SO Shire, Sarah-Jo is also known under banner of Ocean Tidings, a platform for environmental sustainability education. I had the great pleasure of speaking with Sarah-Jo via video call, where we discussed the curious case of white sticks that started washing up on Sydney beaches. Sarah-Jo describes the environmental forensics approach that led to the discovery of the peculiar origin of these sticks.
