A pandemic-induced global cri- sis has exposed every fault in our communities, from the impact dirty power has on the air qual- ity of those living in the shadow of electric plants (page 80) to a seafood industry that greatly disadvantages the artisanal fishermen pulling the world’s din- ner out of the ocean (page 108). But each of these fissures is a reminder that we can do better— and an opportunity to do so. How we fix those breaches shapes our path to a stronger, safer, healthier, and more eq- uitable world. Like kintsugi, these efforts require care and diligence— not duct tape and hasty patchwork. Each gleam- ing gold line we create mends our communities so that they’re im- provements on the originals. That tireless work is what this issue is all about. And in the 11- plus years I’ve worked at, with, or for PopSci, it easily ranks as one of our most ambitious and wide-ranging. The stories reach corners of the globe rarely seen before in these pages and high- light efforts to lift up stifled voices. It explores how, even if we’re faced with great adversity, we can use our ingenuity to help humanity not just survive, but thrive. This is not a smokescreen— it’s been a rough year. But it’s also a season for hope. For PopSci, it’s a chance to find the steps to what we know can be a bright, glim- mering future for all of us. I N J A PA N , T H E R E ’ S A method of repairing shattered pottery called kintsugi, in which artisans rejoin shards with gold- laced epoxy. Once the repair is complete, the shimmering veins not only increase the value of the mended object, they also hold on to the beauty of its past life as it continues anew. Kintsugi builds on the philosophy of wabi- sabi, a belief that the aesthetic flaws of age—things like rust, breakage, and discoloration— enhance an object’s overall splendor. Legend holds that the tech- nique arose in the 15th century, when a shogun was displeased with a first attempt at fixing his favorite tea bowl. Conventional practices had clumsily joined the broken pieces with staples, so he instructed craftsmen to find a more elegant solution.
