i really don't know how much do i contribute to minimize carbon emission, although i think there may be a way to know that. considering that there are already a good number of bike commuters today, our collective effort is a good sign of our common desire to minimize the impact of humans on our environment.
but there are also dangers on the road especially for bike commuters. i share the road with other people using other means of transportation: drivers of motorized vehicles, motorcyclists and pedestrians. some of them show little respect for a bike commuter; that is why, there are dangers out there which i need to be alert to every time i ride my bike.
even then, biking to work is becoming part of my lifestyle; it is becoming a way of life, not just an alternative of doing things. personal safety though is necessary, complete cycling equipment which includes helmet, shoes, gloves, back and front lighting, is non-negotiable.
