#HappyPlanet = Happy People. This sentiment was reflected in the General Assembly Hall at the United Nations on March 20 when @Pharrell @pcousteau and @natgeo 's Sylvia Earle all addressed a room full of students on the importance of taking action on #climatechange. One easy way is to sign the LiveEarth.org petition and raise your voice for climate action! #HAPPYDAY #pharrell #pharrellwilliams #internationaldayofhappiness #climate #liveearth
