“Not all introductions worked well. Rabbits were an unmitigated environmental disaster. Unchecked by any natural predator, they bred at a staggering rate and chewed their way across vast areas of pastureland as well as any garden that came their way.”

When possums were introduced in 1837 to start a fur industry, no one predicted that these Australian neighbours would naturalize with destructive enthusiasm, wreaking havoc on gardens and bush alike.

Maize and pumpkin seeds were soaked in water for several days and then blackened with tar before planting – the most effective way to deter rats, mice and birds.

Attempts to control them by introducing ferrets, weasels and stoats did much more harm than good. Although these predators probably killed a reasonable number of rabbits, they also devastated populations of kiwi and raided the nests of flighted birds.

For those dependent on their gardens for fresh food, it was often a case of feast or famine… (One settler wrote), “Strawberries were now so plentiful that… I made 287 lbs of jam…”

Even where the land was more receptive, settlers soon learned to take some precautions before planting their vegetables.

Up to 20 million possums a year were killed during the height of the fur trade, but this barely checked their rapid expansion.

The cool part about naming your kid is you don’t have to add six numbers to make sure the name is available.

[John Howard] led the Government. They had the numbers, and just basically automatically went along with the Americans.

I think there are a number of reasons, not least of which is the personality of the Queen [ Elizabeth II]. It’s very easy to underrate her significance.

Large numbers of people are broken from the notion that the system is working for people, that the system is just or humane or peaceful.

We worry about the seemingly ever-increasing number of natural catastrophes. Yet this is mainly a consequence of CNN.

I think that age as a number is not nearly as important as health. You can be in poor health and be pretty miserable at 40 or 50. If you’re in good health, you can enjoy things into your 80s.

The movers and shakers on our planet, aren’t the billionaires and generals, they are the incredible numbers of people around the world filled with love for neighbor and for the earth who are resisting, remaking, restoring, renewing and revitalising.

President Obama has tried to spin the paltry new job creation numbers as ‘a step in the right direction.’ But, clearly, the small growth in jobs isn’t even keeping up with population growth, much less returning the workforce to a healthy level.
