In the early 80’s, I walked across the Burrard Bridge in Vancouver. Not alone, however. With me were more than 50,000 persons, mostly of my generation, on the Walk for Peace. Loving peace, I think, is one of three important qualities of my generation. 

That desire for peace has been an important characteristic of my generation for a long time. I grew up in the 60’s and early 70’s. At that time, many of us took part in demonstrations（示威游行） against the Vietnam War. Many people of my generation have devoted their lives to world peace, and lately we have seen success: US and Russian nuclear weapons are half their 1980 levels and nuclear disarmament（裁减军备） is agreed upon worldwide. 

Another characteristic of my generation is our participation in the “marriage revolution”. We were the first generation that had access to safe and reliable birth control. The idea of “free love” made it easier for men and women to safely express their love before marriage. The marriage revolution gave us power, especially to women, and the world was changed forever. 

The most important characteristic, however, is that many of us are deeply concerned about the environment. The results of my generation’s activities can be seen everywhere.

Although not all of us have participated, it is sure that we will continue to have a large impact on North America. We are nearing 50 years old, an age where people of my generation will become successful in politics and then, who knows what changes will come.
