Dear Zambia,
The air quality here in Lusaka is made worse by so many old cars on the road that have high emissions.
Of course it is easy for me to call for this ban because I don't have a car. Old or otherwise.
But in all seriousness, whenever I'm riding my bicycle and an old car zooms by me, I have to stop breathing for a few seconds to avoid breathing in all that black emissions from the exhaust pipe
