This 40-page four-color tab contains Earth Day information from National Geographic and USA TODAY, for the 50th anniversary of the holiday.

Inside are interviews with Jane Goodall and Earth Day founder Denis Hayes, as well as explorers, scientists and photographers. Some of National Geographic's best photography is also included.

The back page is open for an ad, and you may replace any of the five house ads with your own. This is available in PDF format only.

Earth Day is April 22.
