This comprehensive report examines the catastrophic consequences of a hypothetical, technologically-induced eradication of oceanic microorganisms, which are vital for Earth's oxygen production and carbon sequestration. It details a cascading series of global ecological and atmospheric failures, beginning with the collapse of marine food webs and widespread oceanic anoxia, then progressing to a severe decline in atmospheric oxygen and a runaway increase in carbon dioxide. The source highlights that such an event, potentially triggered by a genetically engineered pathogen, would lead to an unprecedented mass extinction and fundamentally reset the planet to an ancient, anoxic state. The report concludes by emphasizing the urgent need for robust international biosecurity frameworks to prevent such a "biological pollution" scenario.
