1 . When we think of bicycles, we think of fun and the outdoors. Bicycles give riders the freedom to explore and enjoy the environment and its surroundings. 1
Most people know that this form of entertainment is ecologically friendly. 2 If you are riding a bike, you are helping to reduce air and noise pollution.
In cities across the world, bikes are becoming more and more popular. 3 People ride bicycles to avoid traffic jams on their way to work, school, or shopping. For many people around the world, access to markets and schools would not be accessible without a bike.
4 Some cities, such as Paris and Barcelona, have not only built bicycle lanes but also have introduced a system of renting bikes. You can rent, or use a bicycle in one area of the city and drop it off in another area of the city. Paris now has thousands of bikes for public use, with bicycle stations located throughout the city.
Some South American cities, such as Bogota in Colombia, have a weekly car-free day. 5 On these days, the traffic-related air pollution from old buses and trucks is greatly reduced.
It seems that the bike is a force for good, providing solutions for cleaner cities without leaving a serious ecological footprint.
