Do you think international travel will change in the future?
In my opinion, people will travel even more in the future than they do now. We talk about the world being a global village and I think that our interest in other places will continue. So many people now have relatives who have moved to live in different countries that many people now have a personal connection with overseas countries. There is some concern about the effect that plane travel has on the environment, and I suppose that if ticket prices became prohibitively expensive as a response to this, it could result in a downturn in the numbers of people who go overseas – but I don’t really think that will happen on a global scale as tourism is an extremely important industry. It’s quite difficult to imagine what we will be doing and how we will be living two or three decades from now!
