There would be a dreadful outcry if anyone suggested obliterating, say, the Tower of London, and quite rightly so; yet a unique and wonderful species of animal which has taken hundreds of thousands of years to develop to the stage we see today, can be snuffed out like a candle without more than a handful of people raising a finger or a voice in protest. So, until we consider animal life to be worthy of the consideration and reverence we bestow upon old books and pictures and historic monuments, there will always be the animal refugee living a precarious life on the edge of extermination, dependent for existence on the charity of a few human beings.
