In this episode of Upwell, we speak with Julia Marsh, CEO and cofounder of Sway, an award-winning startup that creates seaweed-based, home-compostable packaging as a sustainable alternative to plastics. 

In the conversation, we discuss regenerative design and examine the plastic packaging landscape, seaweed farming, sustainable supply chains, and the concept of biological circularity.

In this episode of Upwell, we speak with renowned conservationist Kristine Tompkins, president and co-founder of Tompkins Conservation, an organization that has created millions of acres of national parks and protected countless species throughout South America. 

In the conversation, we discuss the process and future of conservation, delve into what it means to "rewild" nature, and explore the importance of cross-sector climate action and community-driven conservation.

In the conversation, we discuss sustainable aquaculture, regenerative farming, and the circular economy, diving into the future of the blossoming kelp industry and the benefits of ocean-friendly food systems. 

In this special episode of Upwell, we chat with Ambassador Carlos Fuller, Permanent Representative of Belize to the United Nations and Vice President of the Conference of the Parties of the UN Framework Convention on Climate Change (UNFCCC).

In the conversation, we discuss the impacts of the climate crisis in Belize and across the Caribbean — from rising sea temperatures bleaching coral reefs and devastating fisheries, to coastal erosion forcing the displacement of coastal communities — and address the urgent need to implement the Loss and Damage Fund.

You can sign Only One's petition to support the Loss and Damage Fund here, and listen to more from Ambassador Fuller in Shores in Peril | Coastal erosion in Belize, our new short film in The Frontline series, showcasing voices from the frontlines of the climate crisis. 

In this episode of Upwell, we chat with Leah Glass, technical advisor at Blue Ventures, an organization that supports coastal communities to rebuild fisheries and restore ocean life. 

In the conversation, we dive into the world of community-led conservation and blue carbon restoration in Madagascar and around the world, discussing the complementary relationship between local knowledge and satellite monitoring tools, the sustainability of small-scale fisheries, and how to finance and advance nature-based solutions at scale.
