A couple of weeks ago, I saw a TV docu (The city in the sky) which was about how many planes and passengers are in the air at any given time, today. They predicted that by 2050, the number would double, and the congestion problem it would cause, particularly over USA.
I immediately thought “BS”, by that time, unless they find an alternate method of powering an Airbus A380, planes will either be obsolete, or so unaffordable that air-travel will be out of reach of the ordinary traveller/tourist.
As for diesel running out, or being banned in other countries, manufacturers will continue to import, and dump them in Australia, and Aussies will be stupid enough to continue buying them.
