Well * petra* your reply shows that you simply don't know what you are talking about.
My son is responsible amongst the South Coast for this area so I do, having listened to him talk about it and explain the issues over the past years. It is absolutely clear that migrant birds will be severely hit at their feeding grounds will be destroyed, the nursery fish beds will be destroyed. Shall I go on because I can if you need convincing?
However, of course as Gove said experts like my son know nothing. Well I am glad my son has wasted 8 years at university, and the past 19 years learning and gaining experience of the issues at stake.
