History's Most Powerful Plants

The video explores the history and significance of scale trees, ancient plants that thrived during the Carboniferous Period. These trees contributed to the formation of coal, a major energy source today. Scale trees were unique, lacking seeds and reproducing via spores. Their vast forests impacted Earth's atmosphere, leading to an ice age and their eventual extinction. Despite their demise, scale trees left a legacy by forming coal, which humans later harnessed for energy.
