Ray Cobbett has spent much of his retirement campaigning with Friends of the Earth's local group in Havant. He turned 80 this year yet shows no sign of slowing down.
Charlie Gilpin and his friend Will Hearle from Lambeth Friends of the Earth local group decided to do our plastic timer challenge. They're amazed at the lengths they have to go to.
Friends of the Earth England, Wales and Northern Ireland has local groups in around 200 neighbourhoods. That makes us the largest grassroots environmental campaigning community in the UK.
