I have two further questions. I will be brief. It is alarming that salmon stocks are down to approximately 15% of what they were in the 1970s. In terms of salmon coming into our rivers, the figure has fallen from an estimated 3 million to possibly as low as 240,000. To what is this attributed? Is it due to marine activity, plastic pollution or global warming? It is an extreme example but we saw images of thousands of dead fish floating on top of the water and on the shores of lakes in Australia. I know a little about salmon. They need to be in cold water. Is global warming a factor? Our guests engage with the people who are dealing with these matters. What reasons are being given for what is happening, which is giving rise to quite an amount of concern?
