<s>[INST] The next text is a question of a member of the European parliament:"Is the Commission concerned about the UK Government's proposal(1) for a new airport on the North Kent marshes, centred on Cliffe, as one of its options for infrastructure expansion in South East England, given the direct impact on the Thames Estuary and Marshes Special Protection Area (SPA) and Ramsar site, one of the most important sites for waterfowl in the UK?  The Cliffe option, if adopted, would spell disaster for the birds and other wildlife of the Thames estuary. Itcould be the largest ever loss of wildlife habitat and countryside to a single development.  Given that SPAs are protection areas designated under the Wild Birds Directive and Habitats Directive, what action has the Commission taken vis-à-vis the UK Government?  Given that building new runways across the South East will do nothing to narrow the growing gap between supply and demand for air travel, which is kept artificially high through massive public subsidies, what steps does the Commission intend to take to address this imbalance?
