Our universe is an endless series of worlds within worlds. From the molecular ones we carry to the vastness of the cosmos, everything comes down to scale. Atmos Volume 11: Micro/Macro looks at patterns, systems, and size—exploring the fragility and interconnectedness of life on our planet, from enchanting microcosms to towering biomes. Its stories examine local and global theories of change, the scalability of solutions, invisible lifeforms and giant megafauna, and the role of micro actors in shaping macro systems: transforming ourselves to transform the world.
