Look up Homo sapiens in the "Red List" of threatened species of the International Union for the Conversation of Nature (IUCN), and you will read: "Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline."
Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to pandemic flu to climate change.
If it is trying to upset Google, which relies almost wholly on advertising, it has chosen an indirect method: there is no guarantee that DNT by default will become the norm.
In December 2010 America's Federal Trade Commission (FTC) proposed adding a "do not track" (DNT) option to internet browsers, so that users could tell advertisers that they did not want to be followed.
After all, it has an ad business too, which it says will comply with DNT requests, though it is still working out how.
Unable to tell whether someone really objects to behavioral ads or whether they are sticking with Microsoft's default, some may ignore a DNT signal and press on anyway.
Priestly explains how the deep blue color of the assistant's sweater descended over the years from fashion shows to departments stores and to the bargain bin in which the poor girl doubtless found her garment.
These labels encourage style-conscious consumers to see clothes as disposable — meant to last only a wash or two, although they don't advertise that — and to renew their wardrobe every few weeks.
Though several fast-fashion companies have made efforts to curb their impact on labor and the environment — including H&M, with its green Conscious Collection line — Cline believes lasting change can only be effected by the customer.
For H&M to offer a $5.95 knit miniskirt in all its 2,300-plus stores around the world, it must rely on low-wage overseas labor, order in volumes that strain natural resources, and use massive amounts of harmful chemicals.
She exhibits the idealism common to many advocates of sustainability, be it in food or in energy.
Americans, she finds, buy roughly 20 billion garments a year — about 64 items per person — and no matter how much they give away, this excess leads to waste.
In the 2006 film version of The Devil Wears Prada, Miranda Priestly, played by Meryl Streep, scolds her unattractive assistant for imagining that high fashion doesn’t affect her.
Soon you'll feel comfortable asking if they've any knuckles of ham for soups and stews, or beef bones, chicken carcasses and fish heads for stock which, more often than not, they’ll let you have for free.
And if you plan properly, you'll know that you only need, say, 350g of shin of beef and six rashers of bacon, not whatever weight is pre-packed in the supermarket chiller.
It's also a good idea to shop daily instead of weekly, because, being human, you'll sometimes change your mind about what you fancy.
After bills, Tony has £60 a week to spend, £40 of which goes on food, but 10 years ago he was earning £130,000 a year working in corporate communications and eating at London's best restaurants at least twice a week.
Impulsive spending isn't an option, so plan your week's menu in advance, making shopping lists for your ingredients in their exact quantities.
When I think of a sad memory, I do what everyone does — try to put it to one side.
With them, there's not the same embarrassment as when buying one carrot in a little greengrocer.
I also remember that the musical play Hair opened on Broadway on the same day — they both just pop into my mind in the same way.
I can recall the day my grandfather died and the sadness I felt when we went to the hospital the day before.
I can pick a date from the past 53 years and know instantly where I was, what happened in the news and even the day of the week.
We often hear media reports that an unauthorized hacker has been able to access a computer database and to alter information stored there.
The hugely popular blog the Skint Foodie chronicles how Tony balances his love of good food with living on benefits.
A further concern is that the use of electronic means of payment leaves an electronic trail that contains a large amount of personal data.
The fact that this is not an uncommon occurrence means that dishonest persons might be able to access bank accounts in electronic payments systems and steal from someone else's accounts.
Given the advantages of electronic money, you might think that we would move quickly to the cashless society in which all payments are made electronically.
For example, Business Week predicted in 1975 that electronic means of payment would soon "revolutionize the very concept of money itself," only to reverse itself several years later.
Although electronic means of payment may be more efficient than a payments system based on paper, several factors work against the disappearance of the paper system.
