They will provide havens for the breeding of fish and the growth of migratory fish such as salmon and seatrout. No we shouldn't be allowed to fish too close to them, just as commercial fishing should be banned within 10 miles of them.
Many people have told me that in the future, the use of renewable energy will not be cost effective.
There is only one answer to that and that is *******s!!
Maybe based on the technology we have now this might be true, but consider this scenario, the world of 2100.
Remember the Hobbit Holes from Lord of the Rings. Well in the future we will live underground, just like Tolkein's hobbits did. The reason for this is so that food can be grown and the land not covered with concrete. The only sign that someone is living underground will be the nanofibre photovoltaic cell panels which will provide virtually all the energy requirements of the dwelling as well as the supply of electricity for the family car, which will be navigated by computer. Thats right, you won't have to drive it and accidents will be a thing of the past. Driving lessons and other such **** will also be a thing of the past.
Not only that, but the outer shell of each vehicle will consist of nanofibre photovoltaic sheeting which will charge the highly specialised nanofibre batteries whilst the car is both moving or still. The car will not run on wheels by the way, but will be suspended above the ground utilising gravitoelectromagnetism. This technology is real by the way.
Other than specialised jobs, most of which will be performed by robots, we will not "go to work". Work will be done from a workstation in the home where contact will be made with anyone throughout the world. We will certainly not need to go to supermarkets to "shop". Another thing of the past.
I could go on with my vision of the future. It is not based on guesswork, but on technology that is real, and in some cases that I was involved with at the time of my retirement.

Oh and BTW, carbon fibre fishing rods and other sporting equipment will have been replaced by 2020 by nanofibre materials whose base is cellulose. This is a renewable resource that can be grown.
I know that you think I'm talking ****, but there is a fly rod which is available in this country which is made of cellulosic nanofibres. These materials have not been perfected yet but they will be in time, and lots of items which today are based on fossilised hydrocarbons will be made in the future from materials we can grow!
The problem will come in about 20 years time when there could be a third world war, based on the conflict of interests between the establishment who control certain vested interests in the fossilised hydrocarbon industry, and the expanding new technologies, who will win in the end.
