How Plants Caused the First Mass Extinction

The video explores Earth's history 500 million years ago, focusing on the dominance of microbial life and the emergence of the first terrestrial plants. These plants triggered the End Ordovician extinction by altering the environment, leading to oxygen depletion in oceans and global cooling. Despite causing a mass extinction, early plants paved the way for complex terrestrial life by enriching soils and increasing atmospheric oxygen.
