What do you suppose is the biggest threat to planet Earth? It’s a tricky question. Perhaps it can be answered by calculating the relative proportions of news coverage devoted to various global menaces.
Many would say terrorism, and it would be a fair answer, judging by newspaper headlines and daily bulletins. Who couldn’t fail to be frightened by the actions of those who hold life so cheaply? We identify with those who are held hostage and look on in horror as they are shown kneeling at the mercy of their captors and aware of the appalling fate that awaits them. Just when everyone is reeling from suicide bombings some new ghastly and shocking strategy is developed to horrify the infidels.
Then there is disease. Ebola is racing like a bushfire in West Africa, threatening to spread into the wider world. Even if it is to be contained some other, terrifying disease will take over and need to be subdued.
And what about resistance to antibiotics? This could constitute the biggest scare humanity has known since the wonder drug that is penicillin was invented.
Wars? Famine? Financial meltdowns? There are plenty of world disasters to choose from. But to me the single most compelling, the most threatening and insidious peril is climate change-overwhelming all other dangers like an eclipse.
Take Australia. The country is suffering from ever hotter and drier summers, rendering increasingly more of the land uninhabitable as fires and soaring temperatures become the norm. A similar picture is painted in parts of Africa. In other areas of the world flooding and torrential rains have made life untenable as people seek ever more inventive ways to survive. In the future populations will need to move into the parts of the planet that can be lived in comfortably [http://www.theguardian.com/environment/2014/sep/28/climate-change-has-arrived-global-warming-icecaps-deserts].
This summer, whilst on our travels we met several couples who had travelled north from their southern Spanish retirement idylls to seek cooler conditions further north [in the South of France]. One couple explained that around their hilltop villa near Cadiz the temperature was too hot [in the 50s] to go outside and uncomfortable inside with the air conditioning unit going full throttle. It must be prohibitive to fuel such air conditioning-what of those who cannot afford the cost?
And what of those who cannot afford to move, make alterations or adapt? They are the unlucky ones; those who had the misfortune to be born in countries bearing the brunt of the climate changes.
Meanwhile we are all sleepwalking into an uncertain future as we bomb each other to smithereens and wring our hands over financial recession. What idiots humans are!
