At Every Depth: Exploring Climate Change and Human Impact on Our Oceans

IIEA Talks

Human impacts on the global ocean are increasing in scale and scope. As we learn more about climate change, plastic pollution, deep sea mining, and overfishing we see more clearly that these impacts alter our relationship with the ocean. Around the world, communities of people are working together to observe, understand, and act to sustain ocean habitats. In her address to IIEA, Tessa Hill, author of At Every Depth, discusses our growing knowledge about the ocean and the changes that threaten it. The discussion provides an overview of the major themes and lessons from the book, and how they apply to people who are working to protect marine environments on a local, national, and international level.
