This week’s topic is variations on a theme. This made me think of a recent visit to the Paris Natural History Museum where all sorts of species are presented. Some are fake plastic replicas, some are – quite realistic – stuffed animals like these North African lions (extinct). A Hyena, not yet extinct nor endangered but diminishing numbers.As to elephants it’s a complete disaster. Let’s not mention it. Here an African elephant.Sperm Whales aren’t performing any better. And this isn’t new. I found this humongous character rather intimidating. Well, that’s where the variations on a theme comes in. Almost none of the species we saw there were in good shape. Almost all of them are either diminishing, or extinct or endangered. I found it depressing that our grandchildren might never be able to see even a film with those animals. Boy! What have we done to this Earth?!
