I understand their concern over environmental issues and the wish to be seen to be doing something about it.
However - i question the motives and committment of some of the protestors. Can these people honestly say that they are never going to fly on a plane for the whole of their lives? I doubt it. Some of the youngsters involved are just doing it because it is a trendy and fun thing to do and will forget all about it when they have a job and a family in later years. We have to pay for the massive security bill just so they can have a bit of fun and justify it to themselves.
I remember being asked to get involved in the Newbury by-pass protests by some friends when i was at Uni. They would be causing criminal damage, laying in front of trucks, etc., and wasting everyones time. My theory was that the road was going to built whatever they did and i had the foresight to see that i would someday be driving down that road and i didn't want to be a hypocrite. It was just a silly phase they were passing through where they wanted to be seen to be anti-this-and-that just for the fun of it.
Surprise, surprise - i met one of these guys that gave me a mouthful for me arguing with them a few years ago and he looked the picture of corporate bliss. He had a job in insurance, a family, a car and annual holidays abroad. It turns out that i was actually the one who ended up having the least impact on the environment.
Flying abroad now and again for a holiday is everybody's privilage and i for one will not be giving that right up. I go on UK holidays every other year (this year was 2 weeks in a log cabin in Wales - excellent!) and use the train when i go down to London every month.
Plane travel is only a small percentage of the emissions output in the world. There are plenty of other less glamorous and fun things we can all do to lessen our impact. I think we need to concentrate more on what our industries are doing and what we ourselves are doing in our own lives. For example - some of these protestors may even be encouraging air travel by buying goods when they are out shopping that are flown form half-way around the world. They should be checking their belongings for any 'Made In China' labels.
I just resent the fact that i am being made to pay for a small percentage of short-sighted people to have a few fun stories to tell their mates. The Police have a lot more pressing matters to deal with in this country such as all the horrific issues that this forum regularly discuss.
I would hate to get knifed by a gang of teenage thugs and the last thought to go through my mind was "I wish one of the 1800 police assigned babysitting duties at Heathrow was here right now".
A bit of a silly analogy - but you get my drift.
Rant over. Back to work!........
