Tackling how racial justice and climate crisis are entangled, this essay introduces a speculative cartography experiment entitled The World We Became: Map Quest 2350. A collaboration between a collective of artists, poets, academics, curators, architects, and activists, this digital humanities project maps global ecological crises and shared Black, Asian, Pacific, Middle Eastern, Latin American, Caribbean, and Indigenous futures. Intentionally produced in a multimedia format, the born-digital speculative design experiment features visual and audio components presenting a planetary vision of the year 2350 as an underwater future in ruins. The atlas connects five transnational imaginaries that rescript the geographic boundaries of what we currently understand to be South Asia, the South Pacific, the Middle East, North America, Latin America, and the Caribbean. Situating nation-state borders as recent constructs, in this creative exercise the natural environment becomes a model for imagining interspecies relationality and co-presence. Mangroves and atolls form portals to speculative futures of non-human existence beyond the climate crisis and the impact of racial extractive capitalism. Anchored in five locales, the collective text brings together a global vision of survivance addressing migration, dispossession, Asian diaspora, Native sovereignty, Black fugitivity, and broader questions of global indigeneity. With life emerging from the ruins, this atlas forms a digital blueprint of suboceanic futures and the practice of interrogating what justice could mean in the far future.
