This’ll make you think – good numbers here.

I’m ducking in and out between misty showers, trying to build the glasshouse, as I try and keep the tools dry. Jaryd has just pulled into Akaroa, with tales of a wild night under storm-jib. Ish is presumably asleep on a superyacht in Rhodes. Jen is relieving-teaching today, and Zeb is still scared of the turkeys.

This, however, is a good reference on growth, area, population and numbers. I’ll keep it as a reference.

Here’s a wee taste:

First question – how many years to hit one acre per person? Not quite 140 years. By the year 2140, a planet-wide growth rate of 1.3 percent a year brings the entire human race down to only an acre of land per person.

Second question – how many years to hit one square foot per person? About 960 years. Less than ten centuries. About half the institutional age of the Catholic Church. It’s unimaginable but true. If today’s growth rate of 1.3 percent a year were sustained for another millennium, the land per person ratio would shrink to one square foot apiece.

I’m off back out to do another rivet. Hopefully.
