And I really don't get why the old chestnut about transport is dragged out every time, from a small minority who seek to justify the disgusting pollution which is cigarette smoke.
Using a car is essential for some people.
I would quite happily walk to work if it wasn't 20 miles away.
Oh and I'd very happily use the bus (although of course, that produces pollution too. Unfortunately the first bus isn't until 8.30 and I need to leave for work at 7.10
Therefore I drive my small, as economical as possible, car.
I agree that people who make unecessary journeys in huge great tanks of cars are selfish and irresponsible - but frankly, anyone with half a brain cell realises that fuel costs are such that it's bloody idiotic to drive a larger car than you need on and do non essential journeys.
So - there is a need for cars, buses, trains, planes - though I entirely agree that it isn't as many as are on the roads/rails/in the sky
There is no need for anyone to smoke, and if they do, they should keep their smoke to themself.
