The reason people look at differences over similarities has plagued humans in their search for peace for many years.It is this reason that members of several nations created Interdependence Day.”We don’t think often about what we have in common or how we affect each other,” said Dr. Dorothy Bay, professor of biology. “Thinking about these things is to our benefit. It’s a small world and the things we do affect other people and the things they do affect us.”Bay said by thinking about these things in our daily actions the world will be a “healthier” place. “It’s a day to celebrate and learn about how other countries depend upon each other,” she said. Bay said learning toleration is another reason to observe the day.”If we don’t we are going to annihilate each other,” she said. “If one country, say, uses up all the oil, then everybody else won’t have any. If one country pollutes all the water, then other people won’t have any. If one country believes their religion is the only one and the feel like everybody else needs to be killed off, then that’s a problem for everybody else.”Eight people will present their information beginning at 9 a.m. on Friday, Sept. 11 in Corley Auditorium.
