The key question facing the world is: how can we sustain a decent quality of life for all humanity without wrecking the planet. Right now we are definitely not doing this, the world's population is growing, and we're heading for disaster.
The average citizen of a developed or fast-developing country has an ‘ecological footprint’ so large that if everyone on the planet lived that way we’d need at least three planets to support them! But we only have one lovely planet Earth.
On average, for every human being on the planet, it is as if we had 1.7 planet Earths.
