What is changing? This: the contradictions and predations of patriarchal imperialist capitalism, and of the deeply racist and gendered material and symbolic order it produces, have enabled an accelerating, unrelenting, unfettered extractive stance toward the planet, its ecosystems and natural resources, and the plant and animal species and human beings that inhabit it. That stance has not only resulted in increasingly outrageous inequalities and concentrations of wealth; it has gotten us to the brink of climate catastrophe, ecosystem collapse, and a vast, literally unimaginable intensification and expansion of human immiseration and suffering. So what is changing in security (if not in security studies, critical or otherwise) is everything-from the entire context of stable planetary ecosystems that gave rise to the way our world is politically, economically and socially structured, to our understandings of those structures, and to our models and theories of what constitutes security within them, be it state security or human security. We can no longer claim to be thinking about security unless we address the model that conceives the purpose of economic activity as ever-increasing 'efficiencies' of extraction, exploitation and consumption of nature's resources, and of human labour, both paid and unpaid, for the purpose of profit-rather than, for example, conceiving the purpose of economic activity as meeting human needs for a decent and dignified life, and ensuring the sustainability of the resources and ecosystems on which life depends. Consider just these few snapshots of what that model has produced: How is it possible to talk about 'security' while ignoring them/without centring them? 862912S DI0010.1177/0967010619862912Security DialogueSalter (ed.) et al.
