Motorbikes, not cars, the environmental threatMotorbikes from the 2000s generate 416% more hydrocarbons, 3,220% more nitrogen oxides, and 8,065% more carbon monoxide than motor cars made in the same decade, research reveals. An article published recently by the website Green Choices recommended that environmentally-conscious consumers switch from motor cars to motorbikes, as they provide the individual freedoms associated with cars but at a lower environmental cost. On average, motorbikes from the 2000s generate 416 per cent more hydrocarbons, 3,220 per cent moreitrogen oxides, and 8,065 per cent more carbon monoxide than motor cars produced in the same decade. Building better, faster public transportation systems alone will probably not help convince residents to travel greener. A step-by-step approach for every five years, taking into account realistic prospects of public transportation use, is the most pragmatic alternative.
