Warren Buffet. To encourage him to use his bully pulpit to support corporate investment in sustainability and also I would ask him to stop working with 3G, an activist investor which pursues a strategy of cost-cutting—eradicating jobs, ignoring environmental issues, to the detriment of society, and often the company (as has happened with Kraft Heinz).

Building the Rainforest Alliance into an international brand and change-maker that transformed the coffee, cocoa, tea and forest industries to be more sustainable—at scale.

Persuading Stern to let me launch a Center for Sustainable Business at the school, and in three short years, creating sustainable business specializations for grads, undergrads, on-line learning certificates, executive courses, robust and pragmatic research on sustainable business published in top business journals, and well-attended thought leadership events.

1. My husband died at 28, a few months after we were married. I was 3-months pregnant. Living through that, I decided that I really could do anything I put my mind to and because I know knew life was short, I wanted to focus on things that mattered.

2. When I lived and worked in Costa Rica in the late 1980s, activist environmentalists boycotted McDonalds over “rainforest beef” They were right about the unsustainable practices, but they were wrong about their tactics, because when beef demand plummeted, people didn’t stop cutting down trees—they needed to feed their families so they switched to slash and burn agriculture. So I got very interested in how to help people have sustainable livelihoods while producing products that protected the environment.
