Pour yourself a cup of tea and get ready to chat with Laurie David on Feb. 22.

Editor’s note: The chat’s now over, but you can replay it in full.

Laurie David — film producer, climate activist, and author — is chatting live with Grist readers.

David is probably best known for producing the 2006 Academy Award-winning film An Inconvenient Truth, for authoring the best-selling Stop Global Warming: The Solution is You!, and coauthoring The Down-to-Earth Guide to Global Warming.

After a decade working to bring the issue of global warming into mainstream popular culture, David has expanded her purview: Now she’s taking on sustainable eating and reforming our broken food system.

David has collaborated with Rodale and the Grace Foundation to publish On the Future of Food, a book based on a speech given by Prince Charles in 2011. The book is a call to action about the social and environmental impact of today’s food system and an argument for feeding the world with sustainable agriculture.

We’re discussing Prince Charles’ speech, David’s motivation to get it to as many Americans as possible, and her path to food-related activism.

We’re also talking about her recent home-eating guide The Family Dinner, and the connections she draws between cooking at home and greening our food system.

More about The Family Dinner, from David’s website:

With input from more than 50 experts in everything from parenting to poetry to pasta, this book is chock full of fantastic family-approved recipes, dinner conversation starters, ways to express gratitude, green values for the kitchen, and a whole lot more. The Family Dinner will help families cut through the fog of computers, television, texting and busy schedules and will help overwhelmed parents re-discover the joy of this time honored ritual.
