In terms of energy input vs. output, bikes are the most efficient form of transportation ever invented. In Europe, cycling accounts for more than 20% of all trips taken in urban cities. These numbers blow American cities out of the water, where only 1% of trips are taken via bicycle. Part of this difference is the result of a far superior cycling infrastructure in Europe compared to the United States. But the trend is beginning to change. According to city officials, Washington D.C. currently has 50 miles worth of bike paths and is preparing to install and additional 30 miles. In addition, the city has a public bike program that gives subscribers access to bikes in various locations, and there are plans to greatly expand the service. Several other American cities, including Denver, Minneapolis and Boston, are testing out public bike sharing programs as well.
Riding a bike is an incredibly positive activity not only for human health but for the planet's as well. Biking 4 miles to work 5 days a week saves 2,000 miles worth of driving and 2,000 pounds of carbon dioxide emissions. We should encourage our local legislators to expand bike paths and programs in our cities as a way to make a personal stand against global warming and for a healthier future.
