Members of Extinction Rebellion are planning a protest at York Minster this weekend.
The parents and families group of the climate group will stage a peaceful demonstration next to the statue of Constantine on Sunday between 11am and midday.
They are inviting “all people who care about children’s future in a time of climate chaos to take part”.
Activists will sit together in an outwards-facing circle holding personal placards. The protest is part of the Mothers’ Rebellion climate justice movement.
There also will be an opportunity for those who wish to say a few words about why they are participating.
Children are welcome and encouraged to play inside the circle. Parents with children attending are asked to bring a toy and/or a picnic blanket to share.
Those not wishing to sit on the ground are advised to bring a chair, stool, or cushion.
Nina Griffith, member of XR Families York and Parents For Future North Yorkshire, said: “As a mother of young children I am deeply concerned about the worsening climate and biodiversity crisis before us.
“The most frustrating thing is that the science is clear. We know what the problems are and we also know what the solutions are to address them: leave fossil fuels in the ground and end industrial animal agriculture.
“Yet the politicians just aren’t listening. We have organised this Mothers’ circle to show our support for a Global Fossil Fuel non-proliferation treaty to end fossil fuels. We refuse to be bystanders, we refuse to look away.”
