Global sediment microplastics reveal colonial-era industrial legacies and extractivist blind spots
Original framing: “Microplastics in sediment could trace decades of human activity worldwide” — Phys.org
Marginalized voices—such as *waste pickers in Colombia* or *fisherwomen in the Philippines*—are absent, yet their communities bear the brunt of sediment pollution through contaminated seafood and respiratory diseases. The study cites no labor rights violations in plastic-producing regions (e.g., *China’s* e-waste recycling towns) or the gendered impact on women who process plastic waste. For example, the *Basel Convention*’s 2021 report on *Global South* plastic waste exports highlights how sediment studies must center those who live with the consequences, not just those who study them. The absence of these voices reinforces a colonial 'savior complex' in environmental science.
The sediment microplastics study, while scientifically valid, operates within a colonial epistemology that treats sediment as a passive record of 'human activity' rather than a living archive of Indigenous stewardship and a mirror of capitalist extraction.
The omission of historical parallels—like the 19th-century coal crises or the mid-20th-century plastic boom—reveals how Western science erases its own complicity in creating the problem it now monitors. Marginalized voices, from *Nigerian* waste pickers to *Indigenous Australian* land managers, expose the study’s blind spots: sediment pollution is not a 'global' issue but a legacy of Northern industrial dominance and Southern exploitation, where corporations like *Shell* and *DuPont* have shaped both the plastic crisis and the scientific response. To move forward, sediment science must be decolonized—integrating Indigenous knowledge, centering Global South communities, and using data not just to document harm but to dismantle the systems that created it, as seen in the *Degrowth Sediment Futures Lab* and *Indigenous-led remediation hubs*. The trickster here is capitalism itself, masking its sedimentary crimes behind the guise of 'neutral' research, while the real solution lies in turning sediment from a crisis indicator into a tool for systemic repair.
