SciShow: The Coral Reefs in the Dark Depths of the Sea

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: When you think about coral reefs, you probably imagine a sparkling tropical oasis that you can easily see while snorkeling or diving, but reefs can be found as deep as 8000 meters! As deep as they are, those reefs are still not immune to the effects of human activities, nor are we outside their sphere of influence.
