I found Alex when listeners sent me an opinion piece in the New York Times he wrote, The Story You’ve Been Told About Recycling Is a Lie.

Getting to where I take years to fill a load of trash means I've researched waste a lot, so based on the headline, I thought, "yeah, I've read this story before. I'll skim it so I can say I read it and then move on to important things." Instead, I was fascinated and found plenty new. I had to read his book, Waste Wars: The Wild Afterlife of Your Trash, which came out last month. I can't recommend it enough.

Whatever you know about waste and pollution, the book shares more and it's relevant to your life if you value liberty, freedom, justice, not killing people for profit, and not destroying your own health, safety, and security. Our system of waste forces us to act in opposition to those values.

We don't have to. We can change the system. Understanding it helps. Listen to this episode, read Alex's book, and read his opinion piece. Here are its opening paragraphs:

• The NY Times opinion piece Alexander wrote that led me to him: The Story You’ve Been Told About Recycling Is a Lie
• Waste Wars: The Wild Afterlife of Your Trash at Hachette

Silvia created the course Sustainable Marketing at Columbia. It's an elective and has become the class at the business school with the most students from other schools at the university.

In looking for a guest speaker on sustainable consumerism, she found the New York Times profile on me. She decided to invite me before realizing I'd gotten my MBA where she teaches. Only when we spoke did she learn I focus beyond just living sustainably to creating a leadership program with a mission to change global culture.

When I spoke to hear class, I spoke about changing culture, which in some ways conflicted with the marketing goal of selling more products. It also resonated with many of her students' interests in creating a more sustainable world. I got a lot of attention after class. We recorded this episode before I guest-spoke at another section of her course.

We talk in this episode about how that class went from her perspective as well as differences between sustainability leadership and marketing. We did the first part of the Spodek Method. You can hear that as a business educator, she analyzed it, so we talked about that analysis.
