range, suggesting that it has reached its limit. The threat that the new London airport poses to the Brent is considerable. England now provides the winterquarters of half the world population and on the Foulness sands, numbers have reached 7,000. Thus the airport would exterminate more than a fifth of the world population of the goose, for even if some habitat remained, all the large birds, which besides the Brent include 5,000 Wigeon, 200 Mute Swans and countless waders and gulls, would have to be driven away because they would be a danger to the aircraft. The Foulness airport by itself renders the future of the Dark-Bellied Brent Goose dubious, but together with the other prime examples of man's attitude towards estuaries and wetlands, it makes the future seem impossible. By the end of this decade, the vast Delta works in the south of the Netherlands will eliminate

many of the other Brent feeding grounds, and when. further north, the Friesian Islands are linked by dams to cut off the Wadden See, the Brent will have no place in the Netherlands. And in Britain, the Brent will again be threatened if the plans to close off the Wash in a barrage scheme go ahead. One obvious way of solving the problem would be to increase the production of the food plant. Zostera, elsewhere. This idea has already been thoroughly investigated without success but it would surely be sensible to attach much greater importance to this research. Why should it be ignored when the full force of science and technology are applied to the other problems of building an airport at Foulness? One wonders how long it will be before governments are willing to delay technological expansion for the sake of wildlife and its environment.
