Sustainability

  • A Creek I Didn’t Mean to Fall Into

    It was one of those gray SF days. Pandemic era. Everything was closed. I had been in the Bay Area for a bit, but I hadn’t really left the city much. Still very much a San Francisco rookie.

    One day I decided to take the first BART train to “anywhere” and see what happened. It was me, my helmet, and a 1972 blue Schwinn. That bike was the first and is still one of the most important things I’ve ever bought here. Civic Center Station was empty and weirdly echoey. Five minutes later I was sitting on a Yellow Line train headed to a place called Antioch. Never heard of it before. Felt like a good start.

    Then the journey began.
    Arrived in Oakland.
    Still gray and probably cold.
    Let’s keep going.

    Then something changed

    The train went through a short tunnel and suddenly everything was different.

    Bright blue sky.
    Warm air.
    Green everywhere.

    It felt like I had crossed a border I didn’t know was there. Like stepping into a different world without customs. Turns out that was Orinda. I had just discovered the magic wall that is the Oakland Berkeley hills. The same hills that trap SF fog like an overachieving gatekeeper.

    I stepped off the train in awe. The sun hit different. The neighborhoods hit different. Rolling hills, bike paths, tree-lined creeks, a place that felt like it wasn’t trying to be cool and somehow already was. Like a scene from Stand by Me. I explored Orinda, Lafayette, Danville and eventually Walnut Creek. By the time I rode back home, I was obsessed. I told my roommates we should move. A few weeks later, we did.

    That was the start of all this.

    I’m writing this now from Walnut Creek, after spending the day walking downtown, riding the free shuttle that still feels like a small miracle. Free public transportation felt like something out of science fiction, especially coming from Brazil where the answer to that idea was always a loud no from anyone in a suit.

    Contra Costa County figured out a way. County Connection, local taxes, partnerships and maybe some leftover 70s optimism. It’s not perfect but it works, and it still blows my mind. This whole thing allowed us to not have a car and rely on bike paths and public transportation.

    I’ve met incredible people here. Folks from Sustainable Walnut Creek, SCOCO, city staff, retired scientists, former mayors, teenage activists. I somehow ended up organizing Earth Month events and even a climate march. Things I never pictured myself doing. Turns out if you spend enough time outside and say yes to enough random emails, unexpected things happen. And you meet people you actually want to see again.

    Making friends as an adult isn’t easy. Making friends while cycling and volunteering is almost like cheating. You keep bumping into the same faces. You see someone having a picnic and it turns into a conversation. Then another. That’s how it starts.

    I became so obsessed with Walnut Creek that I decided to bike/run every single street. No idea why. I’m at 75 percent, around 231 miles out of 307 and I’ve covered around 20 percent of Contra Costa County. Even gated communities couldn’t stop me. Sometimes I would wait for someone to open the gate and sprint in like a raccoon. If you saw complaints about a confused cyclist on Nextdoor, that was probably me.

    Then there’s Mount Diablo

    My first time climbing it took me seven hours. Same old Schwinn. I had a crisis halfway up. I promised myself I would never do that again. But when a mountain stares you in the face every morning, you eventually give in. I’ve climbed it many times since then (New bike though). Once I even saw snow falling at the summit. It was unreal. I once challenged myself to climb it seven times in one day. Never made it past one and a half.

    Walnut Creek is framed by hills and a mountain that keeps refusing to stay in the background. It’s a place that doesn’t care if you quit halfway. It waits. It just keeps being itself.

    Bookworm life

    The libraries here are wild. Some are over 100 years old, started by women’s clubs who also organized community festivals and clean-ups. Many of the city council members over the decades have been women. That kind of energy sticks to a place. I live close to the Pleasant Hill Library now, which might be the best place on earth on Saturday mornings, especially after a coffee from Rooted Coffee in Poet’s Corner.

    Once Leandra caught me sleeping in the library, I officially became one of those elderly people who nap there.

    I’ve spent years trying to understand what exactly this city does to me. Why it keeps pulling me in. Maybe it’s the weather. Maybe it’s the bike paths. Maybe it’s the fact that people bring up things like graywater systems in casual conversation.

    Maybe it’s something else. Maybe it’s just the feeling that a place can start as an accident and somehow end up as home.

    Whatever it is, I’m still here. And it still feels right.

    Lately though, there’s been a quiet itch. Not to leave for good, but to look around. To see if there’s another corner of this country that feels this charged, this accidental and somehow perfect.

    I don’t know what I’ll find. I don’t know if I’ll find anything. But I do know that no matter where I go, a part of me will always be here. Somewhere between the library and the mountain and the street I haven’t ridden yet.

    And there are the people. The ones I’ve shared bike rides and late-night strategy meetings and awkward first hellos with. Leaving means risking the kind of drift that happens when life changes shape. I’m not ready to lose that. I hope geography doesn’t get the final say on who stays close.

  • A Drop Ripples Outward

    When I first moved to San Francisco, I felt like just another tech bro leech, slurping up overpriced coffee, making rents go up, sucking the life out of the city, and giving absolutely nothing back. I had the whole starter pack: pitch deck, startup hoodie, a head full of “move fast” mantras that sounded deep at the time but now feel like bad Twitter threads. I told myself I was “creating value,” but honestly, I was mostly just creating slides.

    Somewhere along the way, I bought into the idea that if what you’re doing isn’t “scalable,” then it’s not worth doing.

    You know the voice:

    “Damn Dieguito, you should be doing something globally impactful. Think local, act global.”

    – My startup brain parasite

    It’s a catchy mantra, but sometimes it blinds me from the stuff right in front of me, the things that don’t scale, don’t monetize neatly, and don’t promise unicorn exits. That little whisper in my head can make me dismiss real things (like the people planting trees in our park) while I chase hypothetical millions.

    Then, on a rainy Tuesday morning, I went to an event organized by Nadine Hammer (half meetup, half community forum) where folks gathered to talk about sustainability and a new city project. I’ll admit it, my expectations were low. Who the hell shows up on a random weekday morning to talk about creeks and climate? But surprise: a lot of people did. Passionate, curious, caffeinated people.

    Talking about coffee, you know that Starbucks gives free coffee for non-profit events? We got our portion of it. Nothing like free caffeine to fuel a conversation about creek restoration and circular economies.

    So, I met (and re-met) folks doing the kind of work that doesn’t hit TechCrunch headlines. Hyper-local stuff (if that’s a category), like running a library program, upcycling fashion, or restoring a single overlooked stretch of creek. Tiny, unglamorous projects that keep the world stitched together in ways we only notice when they’re gone. These aren’t people waiting for Series A funding, they’re the ones showing up with gloves, clipboards, and a lot of stubbornness.

    Take Civic Park in Walnut Creek. Have you been lately? Four volunteer-run organizations have been working there for years. Thanks to them, you can now actually see Walnut Creek’s creek (the few original pieces of it that survived). Years of persistence, patience, and picking up trash that no venture capitalist would fund. They didn’t need a growth strategy; they needed boots and trash bags.

    One funny thing about this is that while I was helping a group of people plant and water oak trees in an open space restoration area around the city, the drought is so severe here that it’s really hard for those trees to survive. So my mind kept wandering.

    How can we scale this? Can’t we be more efficient?

    – Pa.. pa.. parrot brain

    I went back to the drawing board to come up with a solution that could make a huge impact in remote areas: automated irrigation drone stations powered by sunlight that charge and release drones 24/7 to collect water from a nearby pond and drop it on recently planted trees (inspired by Nathan’s project). The survival rate would increase greatly, and it could drastically reduce wildfires in the future, ping me if you have a billion-dollar check ;p

    But something I was missing while dreaming about that is that part of the whole experience is to strengthen my bond with the city and make me pay more attention to my surroundings. Once you notice, you can’t un-notice. You start seeing these efforts everywhere. Someone teaching kids how to compost in a library basement. A group fixing up old bikes for free rides. Upcycling clothes workshop. Seniors everywhere picking up trail trash. None of it scales. All of it matters.

    A small creek is where life starts. Water flows to rivers, to the bay, to the ocean. And, if you let it, it also flows to connections: to people, to ideas, to myself, to hope. It’s humbling to remember that something as overlooked as a trickle of water in a city park can link to everything downstream.

    That brings me hope that… local work ripples outward… and that ripple is global…

    That these small, stubborn efforts I may dismiss as “too local” are the ones that might actually matter. The ones that sneak under the radar while I’m busy pitching “the next big thing.”

    Not everything needs a hockey-stick growth curve. Sometimes the curve is just water bending around rocks in a creek, reminding us that slowing down, changing course, and flowing steady can be its own kind of success. And honestly? That’s enough.

  • Earth Day, Big Dreams, and Small Beginnings

    I recently had a conversation with the global team behind Earth Day, and I left that call completely blown away by the passion and meticulous organization behind the event. They are behind tens of thousands of Earth Day events worldwide, including one right here in my city. It got me thinking about how far I’ve come from those humble days of orchestrating little movie theater sessions for kids at a local fair in Brazil. Back then, I never imagined those early experiments would someday lead to coordinating large-scale Earth Day events with city partners (which always brings back memories of dealing with Brazilian politicians), churches (even though I’m agnostic), and sponsors (since I admittedly suck at pitching).

    I’ve always had this odd notion that I wasn’t cut out to be an event guy, the idea of organizing something only to see empty seats used to terrify me. Yet here I am, spearheading events run by 100% volunteer-based nonprofits, operating on shoestring budgets, or sometimes, virtually none. Every event is a leap of faith, and despite the occasional panic, there’s a thrill in watching it all come together, even if it means sometimes laughing off the worst-case scenarios over coffee.

    The volunteer spirit is at the heart of these events, but even passion comes with a price tag. Sponsorships enter the picture, each with its own mission and set of values. This year, for instance, we were approached by a wide array of organizations, from big sports clubs and banks to electric vehicle companies. It’s a constant balancing act, because while accepting sponsorships can boost our budget and extend our outreach, it can also tether us to partners whose values might not fully align with our environmental or ethical stances.

    Declining sponsorships feels like a double-edged sword; on one hand, it might mean fewer resources and a smaller reach, and on the other, it reinforces the pride I take in keeping our mission uncompromised by external interests that delve too deeply into environmental or political controversies.

    In the end, these Earth Day events are more than just a calendar date; they are a testament to the unpredictable, often messy journey of turning small beginnings into meaningful, community-driven celebrations. And while the challenges are many and the stakes sometimes feel higher than a teenager’s first crush, the shared commitment of everyone involved makes every moment worth it.

    Here’s to the unexpected paths, to volunteers who show up rain or shine, and to keeping our footprint light on the planet and heavy on authenticity.

  • The Return of the Fly

    Fifteen years ago, I went down a rabbit hole that was mostly larvae. Specifically, Hermetia illucens, better known as Black Soldier Flies. I was obsessed. Not in the “cute pet bug” way, but in the “what if this insect could help save the world” kind of way. I read everything I could find, told anyone who would listen, and probably came uncomfortably close to trying one on toast.

    Then, like most fixations that aren’t actively paying my rent, it faded into the background. The flies flew away and ruined my neighbor’s orange production. 🤷‍♂️

    And now here they are again.

    They’re buzzing through headlines as the next big thing in sustainable food systems. The BBC recently put out a piece painting them as miracle workers. They eat food waste at astonishing speed, turn it into compost and protein, and don’t demand much in return. No water. No land. No feelings about being farmed. It’s the kind of efficiency that makes engineers giddy and environmentalists hopeful.

    Here’s the article if you want the sunny version:
    😊 The little bug with a big appetite – BBC

    But of course, it’s never that simple.

    Another group, the Stray Dog Institute, offers a colder take. They argue that industrializing insect farming doesn’t magically clean up the ethics or the waste problem. Feeding bugs to livestock still props up factory farming. And food waste isn’t just a disposal issue. It’s systemic. Solving it with bugs may just be tech-washing a deeper problem.

    Their article is here:
    😞 Black Soldier Flies Are Not an Ideal Solution – Stray Dog Institute

    So where does that leave me?

    Still weirdly into these flies. Still not eating them. Still wondering if our future involves more systems thinking and fewer silver bullets. I think both articles are worth reading. The optimism and the criticism. The innovation and the discomfort. That’s usually where the real stuff lives.

    What fascinates me most isn’t just the bugs. It’s the recurring pattern. We find something promising. We scale it. Then we realize scaling anything comes with trade-offs. Then we’re left to decide if the trade-offs are worth it or if we’re just trying to avoid the harder questions.

    For now, I’m just glad the flies are back. And that I still care.

  • No gimmicks, please!

    Want to boost your team’s productivity? Here’s an amazing list of strategies that I’ve been incorporating during the last 2 years.

    – Incentives to increase commuting by bike: Encourage cycling to work. It’s not just good for the environment, but those endorphins from exercise can elevate mood and improve focus. 🌿🚴‍♂️

    – Longer lunch times for a quick walk: Allow your team to enjoy a walk after lunch. This reduces the insulin spike and helps maintain energy levels throughout the afternoon. 🍃🏃‍♀️

    – Nature time: Promote spending time outdoors. Being in nature reduces stress and boosts creativity, leading to more innovative problem-solving. 🌳✨

    There are no gimmicks, gamification, or digital tools that will do better than that.

    Today, I had the pleasure of participating in #BikeToWhateverDay, and it was a powerful reminder of how these elements can significantly enhance our mental and physical well-being.

    A big thank you to Bike East Bay for organizing this event and to the fantastic team I met along the way: GU Energy Labs, Backroads, and Sustainable Contra Costa. Your dedication made this experience unforgettable and impactful. 🙌🚴‍♂️

    Let’s incorporate more outdoor activities into our routines to foster a happier, healthier, and more productive work environment. Together, we can pedal towards a sustainable and successful future! 🌍💚
