In the wake of the Santa Barbara shooting, the hashtag #NotOneMore has taken over social media and become the mantra for increased gun regulation and attention to mental health issues. The phrase originated from the father of one of the victims, who made the statement, “Too many have died. We should say to ourselves: not one more.” Postcards printed with the three words are also being sent to representatives to encourage laws to reduce gun violence. (Fast Company)
