It is not quite true that behind every great fortune lies a great crime. Musicians and novelists, for example, can become extremely rich by giving other people pleasure. But it does appear to be universally true that in front of every great fortune lies a great crime. Immense wealth translates automatically into immense environmental impacts, regardless of the intentions of those who possess it. The very wealthy, almost as a matter of definition, are committing ecocide.A few weeks ago, I received a letter from a worker at a British private airport. “I see things that really shouldn’t be happening in 2019,” he wrote. Every day he sees Global 7000 jets, Gulfstream G650s and even Boeing 737s take off from the airport carrying a single passenger, mostly flying to Russia and the US. The private Boeing 737s, built to take 174 passengers, are filled at the airport with around 25,000 litres of fuel. That’s as much fossil energy as a small African town might use in a year.
