If there’s one thing that connects all humans, it’s that everything we walk on, breathe, drink, and eat comes from the same source: planet Earth. From composting to cooking to taking climate action, today’s guests (including Chef Sean Sherman, comedian Jo Firestone, and activist Luisa Neubauer) share the many ways they try to connect to and protect the home we share-- and invite you to get involved in whatever way you can. You can check out TED’s efforts to build a world that is safer, cleaner and fairer for everyone at countdown.ted.com.
