This book explores technology and the global tech industry in relation to social, health, economic, and environmental relations and politics. Peter C. Little argues that the power and influence of electronics and Big Tech—from the proliferation of digital platforms to the expansion of global electronic waste streams—is a political-ecological problem that impacts communities and lives in both the Global North and South. From intense resource extraction, industrial pollution, and surging health and economic inequalities, to data-driven surveillance, platform economy proliferation and intrusion, and Silicon Valley corporate-power, Little argues that the political ecology of tech matters now more than ever. Based on a mixture of engagements with tech criticism, ethnographic case studies, and critical analysis and development of guiding concepts—ranging from technocapital to technoprecarious political ecology—the book exposes and interrogates the underlying toxicity, precarity, and planetary politics of global tech. Critical Zones of Technopower and Global Political Ecology also tracks justice struggles that confront technopower, including “just tech” forms of social action that further reinforce the importance of a global political ecology of technocapitalism in the digital age.
