This is a Buglife campaign and petition, to try to save Swanscombe Marshes in Kent from being turned into a pointless theme park.
To get a feel for the place, see also for example:
It’s a brownfield site, with reasonably intact estuarine marsh, and one of a dwindling number of wild(ish) sites in this part of the world, now dominated by the malls of Bluewater (itself developed in what was once a wonderful chalk quarry) and modern housing estates. Swanscombe Man left his Skull nearby in the heritage park. It’s going going and potentially gone.
