You can do WHAT with seaweed???

Joan Salwen has a thing for cows. After all, she grew up helping her grandfather tend to the livestock on his farm in Iowa. But as an adult, Joan was shocked to learn that cows are pretty terrible for the environment: they burp huge amounts of methane, a destructive greenhouse gas driving climate change. So she built a company, Blue Ocean Barns, around a surprising solution: making feed with a red seaweed native to Hawaii that dramatically reduces cows’ methane emissions when they eat it in small amounts. It’s an innovation that could make farmers like Joan’s Grandpa Mo heroes in the fight to slow climate change. 

In the Season One finale, Joan tells Dwayne about her many professional pivots, from software engineer to middle school English teacher to startup founder; and shares what she’s learned from farmers about how we can all care for our planet. Plus, Joan shares fun facts about cows!
