It’s estimated that the world’s population will balloon to 10 billion by the end of this century. For perspective, that’s like adding the entire population of India TWICE.
A worldwide population of 10 billion means that farmers will have to produce more food before the century ends than has been produced so far throughout all of human history. And yet there isn’t more land to farm. “Nearly every patch of ground has been cultivated, and irrigation for agriculture already consumes seventy per cent of the Earth’s freshwater,” writes Michael Specter in The New Yorker.
