Some things need many hands

These projects are live and only get better with public input. No expertise required — a phone, a balcony, or five minutes of your attention is plenty.

Backyard Biodiversity

Snap a photo of anything alive in your yard — a beetle, a weed, a bird. Each sighting helps us baseline how urban biodiversity is shifting, season by season.

Put a small BreezeNet sensor on your balcony or fence. It joins a low-cost mesh and quietly reports the air where you actually live. We ship the kit; you plug it in.
