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.
