Bike-to-Work Day is held every year across North America on the third Friday of May. It was started by the League of American Bicyclists in 1956. Its aim is to promote(促进) the bicycle as a serious choice of getting to and from work. In today's world where global warming is a serious issue, the bicycle is a perfect way of reducing our carbon (碳) footprint.
Cycling to work is a healthy choice to driving or taking public transport. A healthier society means there is not so much pressure on the country's health system. Of course, it depends on how far you live from your place of work. Another benefit of cycling is feeling more creative and full of energy once you get to work, which will improve your performance.
Bicycles are the most common form of transport in the world. There are about one billion worldwide. This makes it the most popular invention ever. Even in high-tech Japan, it is impossible not to see businessmen, farmers, mothers or workers in the streets on their bikes.
Bicycles were invented in the 19th century and haven't changed much since. Its shape is the same as before. We use bicycles today for amusement, fitness, Olympic competition, mail delivery and lots more. Without the bicycle, much of the world might stop working!
