Volcanic ash is a blessing?

I must admit I enjoy it when Nature tells us, humans, just how insignificant we really are and that the planet is just not under our control, so we better get used to it!

And get used to it we may have to as apparently this phenomenon is here to stay a while.

As long as this volcano in Iceland remains active and as long as the prevaling wind is from the North West and the activity is under the ice then instead of a molten Lava flow we will get minute specs of the same stuff - a glass -sent up into the atmosphere as a result of the reaction we get when molten glass mixes with ice.

This change will result in a massive change in the way transport takes place and we're about to experience the positive side of no planes:

More home produce and goods, quieter skies, less disturbed clouds, less carbon dioxide emissions, more holidays taken in the UK, more knowledge about our own country and stronger British Communities and some might say fewer long distance foreigners (we might get to know the Europeans better).

A chance to rethink our priorities!

Any disadvantages?
