Biking to WorkMore Americans than ever are riding their bicycles to work instead of driving.They are doing this because of gas prices,a slowing economy and concerns about the environment.Riding a bicycle to work does not burn fossil fuel or create dangerous pollutants.Experts say the effects are the most important on short trips.The Department of Transportation says fifty percent of Americans drive eight kilometers or fewer to work.Shorter car trips release more pollution into the air for each kilometer driven.This is because the device in a car engine that reduces the harmfulness of emissions needs to warm up before it can work well.Members of Congress have supported bicycling as environmentally friendly transportation.Cities, counties, state governments and state highway transportation agencies are planning the roadways of the future.They are creating roads and paths for bicycles in cities and between communities.
