An English biologist, Gavin Maxwell tells the story of how two otter cubs were brought to the UK from Nigeria. One morning a Church of Scotland minister was walking along the foreshores of a nearby lake and saw the otter cubs playing by the edge. He pulled out a shotgun and shot them. One of the cubs died instantly, the other died later in the water. When a local journalist questioned him about it the minister replied there was no moral problem for “the Lord gave man control over the beasts of the field.”
