Surely the whole route of the problem is based on pure greed?.

We have various camps telling the public what must happen, or is going to happen, and not be greedy or selfish in the way people run their lives and that of others. Then at the same time we have governments who are impressing on people how they are saving the world, yet at the same time doing things that appear to be in total contradiction of what they say,do or mean.

And this shows no more, when finance and power comes into the equation.

How much natural 'air filteration' systems have been lost over the years for financial reward, and what have governments done about that. Did they stop it or encourage it, and the finance market as had the biggest say and stake in this decision.

I recall the days of the 'pea-soupers', when coal fires were blamed. We closed down many coalfields, at the cost of employment. Yet what as been its replacement, oil and yet another global warning!.

"...a policeman would knock at the door and require you to switch your parking lights on if you parked on the road in a smog."

A friend of my father used to tell a story about how, just after the Second World War he was driving home in a smog so dense that he couldn't see further than the front of his car. He crawled slowly along, following the dim glow from the tail lights of the car in front. They kept stopping at junctions, and in queues of traffic.

One stop went on for so long that he got out of the car to investigate. He discovered that he was sitting behind an empty car; the driver in front had arrived home, and had parked his car in the street with the tail lights still on.
