I enjoy reading the thought-provoking blogs of one of our contributors, Christine Osborne. One of her recent blogs is about the spear fishing of tropical fish off the coast of Australia and how this has lead to the disappearance of some of the large attractive fish such as the giant parrot fish. This definitely has to stop.
