Comment on 'green drivers'

Dear Markus,

I've read your article with interest and have to say that it matches exactly my own opinion. Today's cars are one of the biggest environmental polluters we have to deal with. Their emissions cause an enormous increase of the green house effect worldwide. So the development of ecological cars is a big step towards a greener environment. But as you already said it's our turn to make a change and switch to such cars, because even if some people continue to buy big cars which use up a lot of petrol, the car industry will keep on producing them instead of new, more efficient and environment friendly cars. In addition I would also suggest avoiding driving cars, even ecological cars, as much as possible. In return we should use our bikes more often, because they only run with muscle power.
