* Signed by Robert Downey Jr and Thomas Kostigen * Join Robert Downey Jr. with co-author Thomas Kostigen to discuss their cookbook, Cool Food: Erasing Your Carbon Footprint One Bite at a Time. What we eat matters--to us, and to the planet. Cool Food is a game-changing new food category and way of thinking that can help fix the climate. This engaging and persuasive book will show you how to make simple choices, starting today--in the supermarket, in your kitchen, and in the world--to reduce your environmental impact. Hundreds of cool foods exist, but until now have gone largely uncelebrated for their climate-positive powers. Some of these foods may already be on your shelf, and some are just on the horizon. But cool food is much more than just a shopping list: it's a way of life vitally important to our future.
