At a time when the UK ranks lowest in Europe for nature connectedness and wellbeing – and is, in fact, one of the most nature-depleted countries in the world – the film brings a hopeful message by looking at solutions already in place to restore nature, tackle environmental crises and improve our mental health.

Here’s what you need to know about this must-watch documentary.

A female-led adventure

This new documentary is a Wonderoom film in co-production with Rubber Republic. It is co-sponsored by Triodos Bank and The Crown Estate, with additional support from the Blue Marine Foundation and West of England Combined Authority (WECA). Sea, Land and City follows Mairead Cahill, the film’s creator and founder of Wonderoom, as she travels across sea, land and city to explore innovative nature-based solutions in action. From replanting lost saltmarsh and seagrass meadows to the reintroduction of beavers, which help reduce flooding, the film highlights efforts to revive the environment in an adventure across Southwest England.

“I wanted to make this film to bring to life the opportunity we have to get behind incredible nature-based solutions across the country and reconnect with nature in ways that support our mental health and wellbeing and the health of our economy and climate,” says Mairead.

Inspiring people and projects

Sea, Land and City isn’t just about the beautiful landscapes; it’s about the inspiring people working to make change happen. Whether it’s restoring city waterways with floating pontoons or revitalising coastlines to benefit both wildlife and local communities, these individuals show that solutions are possible.

For example, Rich Stockdale, founder of Oxygen Conservation is at the forefront of efforts to restore our rainforests. In the film, Mairead visits one of Oxygen Conservation's projects, the Leighon Estate, in Devon, to explore how it is enhancing biodiversity while also paving the way for a future shaped by a nature-connected economy.

Another compelling story is the reintroduction of beavers, where Mairead joins Megan McCubbin, zoologist and Beaver Trust ambassador, on a canoe trip down the River Avon. Together, they discuss the incredible impact of beavers as ecosystem engineers, particularly in flood management and strengthening climate resilience.

Through the dedication and vision of individuals like these, the path toward a more resilient and biodiverse environment is becoming clearer - and more achievable.

Why we’re supporting Sea, Land and City

At Triodos Bank, we are committed to supporting initiatives that make a real difference. We know that restoring our depleted natural environment and reversing biodiversity loss is vitally important to our wellbeing and future economic prosperity and will help to mitigate the effects of the climate crisis. We hope that Sea, Land and City inspires further action by showing there are solutions that are already making an impact.

The film premiered at the Blue Earth Summit on 16 October, where Whitni Thomas, Head of Corporate Finance at Triodos Bank UK, joined a panel discussion on scaling nature recovery across sea, land and city.

“One of the key takeaways from Sea, Land and City is its positive and uplifting message,” said Whitni. “We hope people who watch this will be inspired to take one action. One step that helps to make a difference to the natural world.”
