Is it Suzanne? There are many ways to look at this.
Travelling also brings about a lot more cultural understanding that
would be lacking without. This is in all probability a good thing.

Travel is something that is intricically inherent in human nature.
We need only to look at history to prove that conclusively.
Look at emerging economies like China, as soon as the economic
ability is there, there is an urge to travel.

Than said, there is all the reason in the world to make travel as
eco-friendly as possible. We do work at that (I work in flight
operations myself, and am also the environmentalist in our org.).

Aviation has already reduces emissions by 70% compared to the 70's
and noise by 75% in the same period. The current industry
predictions are for a further 50% reduction of both in the next 20
yrs.

Already when compared to car travel you need to be 2-4 persons in
a car to have less emissions. (The actual number varies with type
of car, type of aircraft and the distance involved.)

It is difficult to compare with a train, simply because I do not know
the load factors, the amount of electricity needed, and such. I do
often see that electric trains are sait to be environmentally good -
but as in most cases the electricity is generated by coal or nuclear
power, this is somewhat questionable.
