These yachts are highly popular with the ‘super-bourgeoisie’ – and getting bigger. Can anything be done to stop them destroying our seas?

Who knew? Apparently everyone did, apart from me: you don’t wear shoes on a superyacht. Now, about to step on to my first teak deck at the Monaco Yacht Show, I’ve got to take my trainers off, and I’m having a sock panic. Have they got holes? Do they even match? Do they smell?

To be honest, I’ve come dressed all wrong for Europe’s big annual superyacht trade exhibition. The code for men seems to be crisp and tucked in, blazers and chinos, navy and white, sculpted hair and designer sunnies. (I went colourful, loose, casual). For women, it’s something like Riviera elegance. Everyone – whether they’re Italian, French, English, German, American, exhibitors, buyers, brokers, charterers – seems to know each other. The international superyacht community seems to be a close-knit one, and I’m not part of it. Yet.

In 2022, I helped push through the international agreement to protect biodiversity. Wars and economic pressures can make nature seem like a ‘nice-to-have’. But it is a critical asset, and Cop17 must deliver real action

When I was five, property developers came to cut down the woods behind my home in La Tuque, Quebec. My mother encouraged me to climb one of the trees in protest, then told the developers, straight-faced, that there was nothing she could do when they asked her to get me down. A few days later, the tree was cut down anyway.

I thought about that tree in the early hours of a freezing Montreal morning in December 2022, as the gavel came down on a global agreement between nearly 200 countries to halt and reverse the loss of nature by 2030. I thought about how important nature is for our health, our food security and our economies, but also how much passion there is around protecting it, and how it has the power to inspire people all around the world.
