Fishing is one of the most ancient professions there is but sadly modern fishing has become a threat to our planet. Fish stocks are dwindling and the increase in fish farming is actually having a negative effect on the wild species. Farmed fish often escape and they then introduce disease and bacteria into wild. I love fish. It is one of my favourite things to eat but I am also hugely aware that every time I do I am contributing to the potential destruction of our fragile eco-system.
