Many 100-year-olds mark their milestone birthday with a card from the Queen and perhaps a glass of fizz, but Ti Østmo is made of very different stuff.

Shunning a traditional party, the new centenarian had only one request: a climate change protest on Falmouth's Gyllyngvase Beach.

It stemmed from a conversation with her family about how to celebrate the landmark occasion, with her insisting: "No big party, I just want to know that things are moving in the right direction before I go."

As a result, around 100 people gathered on the beach on Sunday to raise awareness of the need to act now on becoming carbon neutral and tackling the growing climate emergency. They included members of Extinction Rebellion affinity group Marigold.

As expected from such an event, there wasn't a plastic cup in sight and a beach clean was carried out by those gathered at the end.

Ti herself baked around 100 of her legendary scones for those who had come to celebrate with her, and mixed community choir The Suitcase Singers, which rehearses in Penryn, sang a number of pieces for Ti - including one recently written by Claire Ingleheart and Jamie Locke about climate change, called 'Voice of Change', which was commissioned by theatre company Dreadnought Southwest.

Instead of presents she asked friends and family to plant trees, with around 50 collected already and planted as far away as Sussex and even New Zealand.

Her son Gavin said: "Mum has always been a 'natural' environmentalist - riding her bike until in her 80s, growing veg and loving nothing more than to have her hands in the soil. She has been on an aeroplane just twice in her life and has never driven a car.

"Mum's concern about climate change has accelerated considerably since her purchase of an iPad about five years ago, never having used a computer before. She spends a lot of time researching the effects of human activity on the environment.

"Of late, she has been particularly inspired by Greta Thunberg - saying of her, 'If you can do it for the young, then I can do it for the old' - and David Attenborough, whom she holds in high esteem."

Ti lives on a smallholding near Crowan with Gavin and his wife Nicky, where they all moved together - from Norfolk and London respectively - eight years ago, to grow their own fruit and vegetables and learn how to be as self-sufficient as possible.

Then in her early nineties, she would dig out potato beds, limewash outbuildings and tend to the chickens.

Until last November she would walk the half mile into Crowan village on a Friday to catch the bus into Helston - partly to maintain her independence but also to ensure that the bus service was being used.

Unfortunately, on one such trip she fell in the street, breaking her hip and six months on, with a new hip, has been forced to slow down.

Nicky said Sunday's event was "absolutely fantastic," adding of her mother-in-law: "She treads lightly on the earth. She's a remarkable woman."
