In recent years, a number of jurisdictions have recognized diverse ecosystems and other-than-human organisms as legal persons. From national constitutions and legislation to subnational judicial decisions and ordinances, these legal experiments have extended legal personality to riverine and terrestrial ecological communities, including vast geographical areas and the beyond-human beings that inhabit them. A growing body of literature engages with these developments and, in particular, their consequences for states and governments. However, few analyses have considered the practical implications they may present for private organizations operating under company law. We address this research gap and explore potential challenges and opportunities that the recognition of ecosystems as legal persons may create for private legal persons, especially corporations. We also discuss the possible impacts and opportunities of the expansion of legal personality on company law and corporate practice more broadly, arguing for a reimagination of company law. This reimagination embraces an ethics of reciprocity, responsibility, and relationality between corporate entities, and ecological and human communities.
