The jungle is my least favourite environment. It's always damp, and everything tries to bite you, whether it's flora or fauna. But I think it's important to face your fears and not just go for the comfortable option.
As our focus turns to the oceans and the seemingly impossible task of repairing our marine habitat, we could look at Everest as a fine example of turning back the clock.
Lego for many parents is the antithesis of the high tech world. We are desperate to wean our little ones away from the tablets and into the bricks.
Ivory is quickly becoming the new blood diamond of Africa and one that fuels militia battles. Some of the most notorious armed groups on the continent, including the Lord's Resistance Army, are hunting down elephants and using the tusks to buy weapons.
People are being overwhelmed with social issues, political problems and economic problems - and this notion of giving everything up and going to live off-grid and to have a simpler way of life is quite attractive.
Many locals in east Africa are calling for fences to separate wildlife and people. They argue it will reduce conflict and also make it easier to protect the wildlife from poachers. From my experience in Tanzania, no fence and no militia will hold back the tide of poachers drawn by the huge sums of money at stake.
I'm a naturally upbeat person. Friends sometimes compare me to a labrador puppy, and I take that as a great compliment. I love life, I love people and I've got loads of energy right up to the moment when I'm suddenly asleep.
Some people confuse confidence with arrogance. There's no doubt in the business world there are a few big egos and I think arrogance can get in the way. But if you have the confidence to go to your higher superior and say this is wrong, it can make a difference.
What I miss is being close to nature - collecting your own water and generating your own electricity, catching your own food. I still dream of doing that with my own family, even if it's just for a year-long experiment, I would love to have tried that.
I do try to reduce my carbon footprint a little bit by travelling around London on my electric bike. A lot of people raise their eyebrows but I love riding it.
I saw firsthand the devastating consequences of poaching. I saw elephants with ivory hacked from their faces and the lengths private parks go to protect their precious wildlife.
I'm equally happy bouncing across the African savannah in an old Land Rover as I am staying in a luxury resort in The Maldives. Travel and the wilderness excite me.
If you look at the positives, if you test yourself and challenge yourself... I describe myself as a 'yes' person. If you say no to too many things, you think 'what if'.
Hopepunk is a spirit or a mood. It isn't an actual thing. It is a feeling. It is the Scandinavian concept of 'hygge' or 'coziness' of the mind. It is a warm, happy, charming, uplifting concept that leaves you with a fuzzy feeling in your tummy.
After university, I was desperate to be an ambassador. It went back to geography: I loved the idea of living in exotic and exciting countries, but still driving a Land Rover and having tea. I failed the Foreign Office exams three times.
I would hide behind my parents' legs at social events, I was even shy in front of my sisters. I was a really, really ridiculously shy boy. But the one thing I took from my public school education was confidence.
