Villagers in North Yorkshire fighting plans to build a 60,000-home eco-town near where they live have taken part in a protest.
Willow Green would be close to the M62
The town, provisionally called Willow Green, may be built between Eggborough and Kellington.
The idea is part of a government scheme to create carbon-neutral homes across the country.
Campaigners argue the development would "decimate" the environment and their rural way of life.
James Poskitt, managing director of GMI Property - the company behind the plans - said it would help regenerate the area and provide jobs.
Selby councillor John McCartney, who has helped organise the protest, said: "The walk will take place predominantly on public footpaths that will be stolen from us if the insane proposal goes ahead."
Protestors say the eco-town would increase the risk of local flooding and exacerbate traffic and pollution locally.
Jason Johnson, who lives in Kellington, said: "I chose to stay in the village and bring up my family here because of the kind of home life it could offer us - peaceful, picturesque, clean and safe.
"These eco-towns threaten to spoil all that. We already live on the main roads through the village and I have serious concerns about the levels of traffic, noise and pollution if another 60,000 people are shoe-horned around us."
