I stumbled upon a wonderful new video series on YouTube called MinuteEarth that focuses on creating short, attractive, easy-to-digest videos about environmental science. The kickoff video is titled "The Story of Our Planet," which was followed by a two-part series on why leaves are green. Then the fourth piece caught my eye: "How Tall Can Mountains Be?"

Give it a watch.

Click over and subscribe to MinuteEarth. The group's YouTube profile says: "Created by Henry Reich, with Alex Reich, Peter Reich, Rose Eveleth, Emily Elert, and John Guittar. Music by Nathaniel Schroeder."

The world is a better place when more people who scientifically literate, and videos like MinuteEarth are helping to make that happen. Well done all around.
