. >> something you do in your book is you look to history, look attica taat catastrophes from the past guess you could call it increasingly faster moving crisis to do something about it. >> i think the most important thing is to move away from rhetoric and have a plan. with all due respect to your panel that you were just speaking to, referring to the president as simple or as narcissistic or pathological, true as those statements may be, isn't actually accomplishing anything. even worse, it is confusing feeling good about having strong political opinions for doing good in the world. we know there are things we have to do to save the planet. we have to fly less. we have to drive less, and eat less meat. what i would strongly suggest to everybody is to make a plan and give it numbers and days of the week. even more importantly, or as importantly, share that plan with your family and friends. to be honest, i wrote this book about climate change. it wasn't until a week or two ago when i was confronted by a young couple about to get married. they shared their plan with me. eat vegetarian.
