Actually, Swampy's ("Daniel"'s) main cause celebre was the Newbury bypass in Oxfordshire, where the campaign of disruption was carried on for, oh, a year or more(?). Britain is a small country: and roads are overcrowded, but the environmental damage caused by building more and more is proportionately huge. Not only does it build on sensitive environments, but "islandisation" (where particular habitats are sliced into ever smaller areas until they're individually too small to support a viable population of ceratin species.)

Yesterday the government announced a plan to expand a 61 mile stretch of the M6 between Birmingham and Manchester to ten lanes from the current six.

"Here's two cheers for the crazy diggers;
now their hour shall come around
We shall plant the seed they saved
as common wealth and common ground"
