Policing and ecological crises – and all the inequalities, discrimination, and violence they entail – are pressing contemporary problems. Ecological degradation, biodiversity loss, and climate change threaten local communities and ecosystems, and, cumulatively, the planet as a whole. Police brutality, wars, paramilitarism, private security operations, and securitization more widely impact people – especially people of colour – and habitats. This edited collection explores their relationship, and investigates the numerous ways in which police, security, and military forces intersect with, reinforce, and facilitate ecological and climate catastrophe. Employing a case study-based approach, the book examines the relationships and entanglements between policing and ecosystems, revealing the intimate connection between political violence and ecological degradation.
