“Space-ship Earth is hurtling through the void. Its passengers are anxious and fractious, and their life support system is vulnerable to disruption and breakdowns. And there is too little planning, too little horizon-scanning. Our Earth has existed for 45 million centuries, but this century is special: it’s the first when one species, ours, has the planet’s future in its hands.” — Professor Lord Rees OM FRS HonFREng HonFMedSci, Astronomer Royal.
