Environmental and Economic Impact of Coal

The video explores the evolution of human impact on the atmosphere, starting with ancient Rome's glass production, which led to deforestation and pollution. It then explains the formation of coal over millions of years and its initial use by the Chinese. The video concludes with the rise of coal mining in Europe during the 1500s, highlighting its economic significance and the shift from surface to deep mining techniques.
