In the marine context, it depends on what your objectives are. If you're in an area of a high intensity of marine birds, those windmills may not be very amenable to the long-term survival of marine birds that migrate through those areas.
In the marine context, we found that with regard to windmills, the biggest challenge came from the fishing sector, from the crab fishing sector, which felt that its biggest challenge was that operating in the context of those wind farms would impede its fishing opportunities at a level that was unacceptable. There are various socio-economic considerations as well.
