Our trip to the UN was a great experience. Upon arrival we all were asked to line up outside and go in one at a time. We had to check in through security. Entering the building we were directed to go to the auditorium. We entered a huge chamber with lots of seats organized radially. The main speaker would be in the middle. The room was very loud at first. All the students were talking, everyone was excited or very tired. The first speaker was Joel Towers, he introduced the history of sustainability and design.
