Scenarios about 'hazardous materials'

Hazardous materials are substances that pose significant risks to human health, safety, or the environment when improperly handled, stored, or transported. Throughout history, the management of these materials has evolved from minimal regulation to comprehensive international frameworks governing their use, as societies gained understanding of their potential for catastrophic accidents, long-term environmental contamination, and public health impacts. In alternate history scenarios, different regulatory approaches to hazardous materials often serve as critical divergence points that reshape industrial development, environmental movements, and public health outcomes.
