It Seems like Trees Caused a Mass Extinction

The video explores the Late Devonian extinction, a mass extinction event possibly caused by the evolution of trees. This event led to a significant drop in global biodiversity, particularly affecting ocean ecosystems. Trees, with their deep roots and nitrogen-fixing capabilities, may have contributed to algae blooms and global cooling, impacting marine life. While trees are a potential cause, other theories like meteor impacts and volcanic eruptions are also considered. The event highlights the interconnectedness of life and the impact of one species' success on others.
