While saving the Amazon grabs headlines, the trees right outside your front door shape your life in important ways. The more trees in your city neighborhood, the less crime, the fewer prescriptions for antidepressants, and the lower rates of asthma, childhood leukemia, and other immune diseases. These leafy giants affect everything from healthier newborns to longer life expectancy to higher property values. Geoffrey Donovan, an urban forester and economist with the U.S. Forest Service, joins the show. His groundbreaking research over the two decades is reshaping how urban planners and policymakers think about the essential public health and economic role of trees in city life.

In an industry that moved fast and defied cities, Veo chose a different path: partnership over disruption. Co-founder and CEO Candice Xie is building one of the only profitable micromobility companies in America by leading with discipline, transparency, and respect for the people shaping urban life. While competitors flooded streets and flamed out, Veo continues to earn trust — winning 90% of city RFPs and operating in over 50 markets nationwide. Candice joins Josh Dorfman to unpack how Veo’s strategy of asking for permission, designing durable hardware, and prioritizing community needs became its true growth engine. This is a masterclass in scaling deliberately, proving that in 2025, the climate-tech companies that endure aren’t the ones that move the fastest — they’re the ones that build trust the deepest.

Every day, 27 million kids ride 500,000 school buses—the largest transit system in America. And yet, this 80-year-old relic is stuck in the past: buses are late, routes are inefficient, and parents have no clue where the bus is or when it’s coming. Ritu Narayan, founder and CEO of Zum, decided to fix it. All of it.

With real-time tracking, smarter routes, and electric buses, Zum has modernized student transportation for 4,000 schools, including the school districts of Los Angeles, San Francisco, Seattle, and Boston. In Oakland, Zum introduced the nation’s first fully electric school bus fleet, slashing emissions and cutting the number of buses needed nearly in half.

Zum isn’t just about buses—it’s a tech, Human Resources, logistics, and infrastructure company rolled into one. The result? Parents can breathe, kids get to class on time, and school districts finally have a system that works.

Ritu joins Supercool this week to discuss how Zum is making school buses smart, sustainable, and better for everyone.
