This book offers a paradigm-shifting exploration of lawmaking for the complex interactions between Earth systems and outer space. Drawing on complex systems science, posthuman approaches, and plural ontologies, the author proposes a reimagining of law and governance for the cosmic age. Through the “cosmolegal” perspective, this study embraces the inherent uncertainties and complexities of Earth-space interactions. From Arctic methane craters to orbital debris, the book weaves together scientific insights, landscape architecture, legal theory, and doctrine to address pressing environmental challenges that span Earth and beyond. While legal scholarship has increasingly engaged with Earth System Science, it typically treats outer space as distinct from Earth’s environment. However, Earth’s existence and complex systems are fundamentally intertwined with and emerge from outer space. This book argues that a legal framework for Earth’s systems needs to include outer space. At its core, the
