You can only really have a estimate on this, quote"I read that last year over one million rod licences of all types were sold" end quote in my estimation you could safetly say theres a lot more that don't buy the rod licences a good source would be to look at Environment Agency Addition Angling in the UK is often quoted as the highest participant sport there are estimated to be in excess of 3 million anglers in the UK You only need a fishing licence for coarse & game fish A licence is not needed for sea fishing.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
