Of the two modes of transport, I prefer cycling because it helps us practice a nice, elegant sport, but with this gesture, we participate in reducing the pollution of this planet.In my opinion, the most environmentally friendly means of transport are bicycles because it also develops man, but we also help to develop the nature around us.
Pollution of the vehicle cause I do not think it can ever be reduced, but hopefully we will slowly give up those on fuel and we will focus more on the vehicles running on the current, the ecological ones, but also on the bicycles, walking .
