This summer watch the streets of St. Louis for a unique rolling service: a grocery store in a Metro bus. Earthworms guest Jeremy Goss and his partners Colin Dowling and Tej Azad are medical students and an MBA about to launch some serious business.

The St. Louis Metro Market will address food access issues rooted in poverty and racial discrimination. It will run as a business, generating revenue through at-cost sales in low-income neighborhoods and market-rate sales on corporate campuses. Produce supplied by community gardens and sustainable farms will help nourish our Local Food sector, as the bus delivers healthy food to folks in need. Plus cooking demos - and SAMPLES! - will encourage customers to prepare healthy meals.

This inspiring conversation blooms with "good and great" responses to needs of people, the planet - and the process of making a decent living. Follow Jeremy and the Metro bus grocery on Twitter @STLMetroMarket
