Mr. Claes Nobel, a member of the Nobel Prize family and Co-founder of NSHSS, was a passionate advocate for environmental causes. If you ever heard him speak in person, you would know his favorite greeting is “Good Earth” to you. In honor of Earth Day, we share this special message from our archives.

Please share your Earth Day messages, activities and causes with your fellow scholars on social media and use the hashtag #GoodEarth.
