From my travels around the world I have seen how much damage and pollution is done by the careless disposal of waste. It is also evident that we in the West produce far more and throw away far more than the developing world, almost without thinking

I remember queuing around the block in Sheffield when I was growing up. At that time, going to the cinema was really something special - there was something about the style of the real thing that is immeasurable nicer than multiplexes.

There is barely a country in the world where you will be completely safe.

There are people who travel because they want to push themselves to physical limits, people who walk across deserts or cycle across the Antarctic - like Ranulph Fiennes, who just does it because it's there. And then there are people like me, who are just genuinely curious about the world.

Despite having seen a fair amount of the world, I still love travelling - I just have an insatiable curiosity and like looking out of a window.

I wanted to be an explorer, but gradually found the world had been explored and that there was nowhere left, really. Once they climbed Everest in 1953, when I was 10 years old, I thought, 'Well, that's pretty much it now.' But the idea of travelling and exploring and adventure was very strong.
