The global arms industry—worth nearly $95 billion annually—is both a driver of human suffering and a silent engine of ecological collapse. Wars claim over 2,000 lives daily, displace millions, and shatter societies, while leaving behind poisoned aquifers, fragmented habitats, and toxic soils contaminated by unexploded ordnance and chemical residues. Arms manufacturers like Lockheed Martin and RTX thrive on this devastation, rewarded by soaring stock prices whenever conflict erupts, while shadowy brokers such as Viktor Bout and Aboubakar Hima profit from prolonging wars that ravage both communities and ecosystems. India exemplifies this global dilemma, channeling vast sums into defense while underfunding water, health, education, and environmental resilience. The campaign “Shut Down Arms Factories to Stop Wars” demands dismantling this war economy by halting weapons production, regulating brokers with ecological due diligence, mandating transparency of emissions and toxic legacies, and reallocating resources toward human well-being and planetary stewardship. Peace cannot be defined as the mere absence of war—it must mean fertile soils, clean water, healthy bodies, and thriving ecosystems within Earth’s limits. Yet even the green transition carries risks: critical mineral extraction for renewables, if pursued without justice, threatens to replicate the violence and exploitation of fossil fuel regimes. A just future requires confronting militarism, curbing extractivism, and investing in life over destruction. Only by linking disarmament with ecological restoration can humanity secure genuine peace within planetary boundaries.
