text: President Obama's goal to curb the U.S.'s greenhouse gas emissions, unveiled last week. Recent astudies suggest that Americans are buying fewer cars, driving less and getting fewer licenses as each year goes by. Pedestrian, bicycle, private cars, commercial and public transportation traffic are woven into a connected network to save time, conserve resources, lower emissions and improve safety.    Community service is a very important activity in a young ones life, I believe it teaches one to become more responsible. In my opinion, I think community service should defiantly be encouraged! However, I don't think it should be required. Many students may feel it is unnecessary to help out in there community, but after they perform one task of this act, I think they will take it into consideration that parks don't clean themselves, and elderly need friends too. I believe this one little action could change their perspective, and could slowly shape the world into a better place!
