The Green Taboo: Population Control

Original image

It all sounds very Orwellian and nightmarish at first. Governmental controls on how many children a family can have; the ease with which global efforts to slow population growth might unfairly be focused on developing nations; the loss of one of our most basic human liberties, the freedom to procreate. But more and more, respected experts are making their voices heard on the subject -- people like Sir David Attenborough and Dame Jane Goodall, who have joined a British awareness organization called the Optimum Population Trust, which pushes for the voluntary reduction of the British population by at least .25% a year.

Until recently, the Trust says, government policy-makers and environmentalists appear to have been purposely silent on the topic of population growth, engaging in a kind of lie of omission, tacitly implying that the population can continue to grow unchecked forever with no ill effects. (Another Trust initiative is the "Stop at Two" program, the title of which is pretty self-explanatory.) For instance, between now and 2051, the UK population is expected to increase from 61 million to 77 million, but scientists have determined the long-term environmentally sustainable population of the UK to be around 30 million.

In terms of the Earth as a whole, no one's quite sure what its "ideal population" is, but most believe it's less than we have now. There are also per capita consumption issues to address -- the fact that the USA accounts for only 5% of the world's population but uses 25% of its resources, for instance. I'd like to think that we're working on it -- or beginning to, at least -- but without some checks on population growth, experts agree, per capita consumption reduction alone will not solve our problems.

Obviously this is a hotly contentious topic, but at the risk of starting a flame war, I'd love to hear what our readers think about it. How many of you think the "Stop at Two" program has the right idea?

A Simple Way to Charge Your iPhone in 5 Minutes

Spotting the “low battery” notification on your phone is usually followed by a frantic search for an outlet and further stress over the fact that you may not have time for a full charge. On iPhones, plugging your device into the wall for five minutes might result in only a modest increase of about three percent or so. But this tip from Business Insider Tech may allow you to squeeze out a little more juice.

The trick? Before charging, put your phone in Airplane Mode so that you reduce the number of energy-sucking tasks (signal searching, fielding incoming communications) your device will try and perform.

Next, take the cover off if you have one (the phone might be generating extra heat as a result). Finally, try to use an iPad adapter, which has demonstrated a faster rate of charging than the adapter that comes with your iPhone.

Do that and you’ll likely double your battery boost, from about three to six percent. It may not sound like much, but that little bit of extra juice might keep you connected until you’re able to plug it in for a full charge.

Trying to Save Money? Avoid Shopping on a Smartphone

Today, Americans do most of their shopping online—but as anyone who’s indulged in late-night retail therapy likely knows, this convenience often can come with an added cost. Trying to curb expenses, but don't want to swear off the convenience of ordering groceries in your PJs? New research shows that shopping on a desktop computer instead of a mobile phone may help you avoid making foolish purchases, according to Co. Design. Ying Zhu, a marketing professor at the University of British Columbia-Okanagan, recently led a study to measure how touchscreen technology affects consumer behavior. Published in the Journal of Retailing and Consumer Services, her research found that people are more likely to make more frivolous, impulsive purchases if they’re shopping on their phones than if they’re facing a computer monitor. Zhu, along with study co-author Jeffrey Meyer of Bowling Green State University, ran a series of lab experiments on student participants to observe how different electronic devices affected shoppers’ thinking styles and intentions. Their aim was to see if subjects' purchasing goals changed when it came to buying frivolous things, like chocolate or massages, or more practical things, like food or office supplies. In one experiment, participants were randomly assigned to use a desktop or a touchscreen. Then, they were presented with an offer to purchase either a frivolous item (a $50 restaurant certificate for $30) or a useful one (a $50 grocery certificate for $30). These subjects used a three-point scale to gauge how likely they were to purchase the offer, and they also evaluated how practical or frivolous each item was. (Participants rated the restaurant certificate to be more indulgent than the grocery certificate.) Sure enough, the researchers found that participants had "significantly higher" purchase intentions for hedonic (i.e. pleasurable) products when buying on touchscreens than on desktops, according to the study. On the flip side, participants had significantly higher purchase intentions for utilitarian (i.e. practical) products while using desktops instead of touchscreens. "The playful and fun nature of the touchscreen enhances consumers' favor of hedonic products; while the logical and functional nature of a desktop endorses the consumers' preference for utilitarian products," Zhu explains in a press release. The study also found that participants using touchscreen technology scored significantly higher on "experiential thinking" than subjects using desktop computers, whereas those with desktop computers demonstrated higher scores for rational thinking. “When you’re in an experiential thinking mode, [you crave] excitement, a different experience,” Zhu explained to Co. Design. “When you’re on the desktop, with all the work emails, that interface puts you into a rational thinking style. While you’re in a rational thinking style, when you assess a product, you’ll look for something with functionality and specific uses.” Zhu’s advice for consumers looking to conserve cash? Stow away the smartphone when you’re itching to splurge on a guilty pleasure. [h/t Fast Company]
