Abstract: This chapter explores the intricate relationship between memory, space, and white settler colonialism within Canada’s National Parks, using the Canada 150 Discovery Pass—a state-led commemorative program for Canada’s sesquicentennial—as a case study. It argues that these national parks, celebrated as iconic Canadian landscapes, are pivotal to a white settler national identity that necessitates the disremembering of colonial violence and dispossession for their very existence. The Canada 150 Discovery Parks Pass encouraged Canadians to reflect on, project, and imagine what it means to be Canadian through the viewing and spatial transit of these places purported to represent the best of Canada and its citizen-subjects. However, these parks are also sites of forced removals of Indigenous nations, marked by the dispossessive violence of white settler colonialism, which relies on the attempted erasure and forgetting of Indigenous presence. This chapter contends that these parks, while celebrated as iconic Canadian landscapes, are crucial sites for the production and maintenance of a white settler national identity. Drawing on the work of Critical Race scholars and Indigenous artist Rebecca Belmore’s aesthetic intervention, Wave Sound, the chapter demonstrates how the pass consolidates a white possessive subjectivity that justifies ongoing colonial land appropriation and elides colonial history. In contrast, Belmore’s sculptural objects, installed in four National Parks, invited visitors to listen to the land rather than merely view and transit through it, thereby offering an opportunity to challenge official memory and foster alternative forms of remembering.





Description: A revealing look at the parallel mythologies behind the colonization of Earth and space—and a bold vision for a more equitable, responsible future both on and beyond our planet. As environmental, political, and public health crises multiply on Earth, we are also at the dawn of a new space race in which governments team up with celebrity billionaires to exploit the cosmos for human gain. The best-known of these pioneers are selling different visions of the future: while Elon Musk and SpaceX seek to establish a human presence on Mars, Jeff Bezos and Blue Origin work toward moving millions of earthlings into rotating near-Earth habitats. Despite these distinctions, these two billionaires share a core utopian project: the salvation of humanity through the exploitation of space. In Astrotopia, philosopher of science and religion Mary-Jane Rubenstein pulls back the curtain on the not-so-new myths these space barons are peddling, like growth without limit, energy without guilt, and salvation in a brand-new world. As Rubenstein reveals, we have already seen the destructive effects of this frontier zealotry in the centuries-long history of European colonialism. Much like the imperial project on Earth, this renewed effort to conquer space is presented as a religious calling: in the face of a coming apocalypse, some very wealthy messiahs are offering an other-worldly escape to a chosen few. But Rubenstein does more than expose the values of capitalist technoscience as the product of bad mythologies. She offers a vision of exploring space without reproducing the atrocities of earthly colonialism, encouraging us to find and even make stories that put cosmic caretaking over profiteering.






Abstract: Indigenous Peoples in Canada face significant environmental health challenges, including long-term, low-dose toxic exposures that contribute to pronounced health disparities compared to the general population. The unequal distribution of industrial contamination and historical practices such as mercury dumping primarily drive these disproportionate toxic exposures. The authors have conducted extensive research in this area including a community-based case study using a mixed-methods approach integrating community narratives and biomonitoring data. They aim to summarize their findings and potential countermeasure strategies that toxicologists working in public health can apply to define and improve health outcomes among minority groups in middle- and low-income countries.Many efforts have been made in recent decades to reduce exposure rates and restore traditional health practices; however, these communities still face heightened risks from contaminated food sources, ongoing socio-economic inequalities, and the degradation of their ecosystems. Additionally, structural racism within healthcare systems and limited access to culturally appropriate care exacerbate these challenges. This commentary highlights the urgent need for a comprehensive, culturally sensitive environmental health approach incorporating Indigenous knowledge systems and community-driven solutions. We emphasize the importance of participatory, Indigenous-led research to address cumulative health impacts, promote resilience, and reduce health inequities. In conclusion, health authorities can develop sustainable strategies to reduce toxic exposures at the population level and support the health and well-being of Indigenous communities. This can be achieved through collaborative approaches that honour Indigenous sovereignty and embrace the principles of relevance, respect, and reciprocity. These findings have important implications for reducing toxic exposures among minority groups in middle- and low-income countries. Addressing long-term low-dose toxic exposures among Indigenous Peoples in Canada requires culturally respectful and community-led environmental health approaches. Researchers and policymakers must engage in sustained, collaborative efforts recognizing Indigenous sovereignty and tailoring strategies beyond those used for the general population.
