Nice thinking to remain sustainable and keep the earth pollution free.
In today's life, fossil-fueled vehicles' ratios are immensely increased. We are consuming these fuels and producing pollutants daily at large scales while human-driven vehicles are abandoned by humans. We need to think about this. Bicycles not only keep earth pollution free but also it is an exercise and a very good one. If adopt bicycles in our lives instead of motor vehicles, it will cost us nothing except the purchase price, it will improve our health and also it will be good for our upcoming generations.
Inspirations like **Green Cycling** should be encouraged. They did a good job for the environment and for us.
