I think you will find that the RSPB (Royal Society for the Protection of Birds) have just succeeded in in buying a large chunk of Cliffe Marshes.
Sorry, but this time, I'm rooting for the feathered ones.
I believe that we need a orbital rail system that connects to all the main lines into London, a main-line rail station at Hearthrow and a greater use of airports away from London, SND, Manston, Farnborough etc.
