4. We(*) had a glimpse of the improvement possible back in 2010 ...
I loved it when Eyjafjallajökull erupted and we had no major aircraft flying over us for about a week!
The majority of air travel miles are unnecessary - personal indulgences, business meetings
that can (and should) be conducted by phone or video, shipping of luxury exotic foodstuffs from
distant lands to be wasted on supermarket shelves - and so the loss of them (temporarily or, as will
eventually be the case, permanently) is simply at the "inconvenience" level rather than anything
On the other hand, continuing the incredible volume of unnecessary flights is life-threatening on a
global scale so when it comes to stopping it, I say "Do it and now please".
Bring it on!
(*) "We" = "UK & other NW Europeans" along with anyone else who was intending to visit/return from
those places in early April 2010. By way of comparison, the clear skies following 09-SEP-11 would
have given those on the NE USA a taste of it as well.
