A friend raised an interesting question – what’s the impact on the world’s surface of increasing weight? Of the billions of people, buildings, bridges, roads – being added to the globe every day. Are we weighing the earth down? In 1950, the word’s population was 2 billion. Now, it’s 6 billion. If the earth was a set of scales, imagine the number. I thought, if there was an effect, the most populated areas would be dented and concave. I pictured New York as a hammock – an uncomfortable one with the Empire State Building sticking up in the middle. Perhaps I should ask a geologist.
