On Saturday, Oct. 24, the north side of the Bald Spot was lined with 350 photographs of Carleton individuals and their personal answers to this question: “Why do you care about climate change?” Sustainability assistant Arpita Bhattacharyya, one of the six students who spearheaded the project, said that the event was an effort to join the international movement, but also a chance to raise awareness on campus that there needs to be more than just green dorms and wind turbines. The goal of this specific day, coordinated by 350.org, was to influence the leaders who will be writing a new global treaty on cutting emissions this December in Copenhagen, Denmark. The number 350 has been significant ever since scientists determined that 350 parts per million of CO2 is the safe upper limit for our atmosphere. The event, entitled “350 Reasons Why Carls Care,” was one of over 2000 events that took place on Saturday in over 140 different countries.
