Since the COP26 climate change summit began in Glasgow, hundreds of protesters have taken to the streets of the city.
Some, like 17-year-old climate activist Dylan Hamilton, who is part of Fridays for Future, led by Greta Thunberg, prepared for the event for more than two years.
And, in the run-up to COP26, a Glasgow café began storing universal handcuff keys.
Dylan and Miles Grant of the Pink Peacock Cafe have told BBC News why they are taking action.
