If earth looks like a blue marble, why is Earth Day associated with the color green? Also, 'funnest.'

The famous NASA "blue marble" image could have influenced people to make blue the color of environmentalism and Earth Day, but green won the day. In honor of the special day, we look at how the meaning of "green" has changed over time. Plus, we investigate the "fun" continuum and whether it's OK to use the words "funner" and "funnest."
