Materials scientist Debbie Chacra writes about "peak plastic" -- the moment at which our ability to make plastic (which is made from oil) begins to decline. As Debbie points out, our material world is made of plastic, and it's hard to imagine a post-plastics life.
Plastic is more than just water bottles and Tupperware. If you’re indoors, look around. There’s a good bet that much of what’s in your field of view is made of plastic. Paint. Carpeting. Upholstery. The finish on a wood floor. Veneer on furniture. And that’s before you go into your kitchen, or bathroom, and never mind a subway car or a hospital (disposable, sterile medical supplies, anyone?). Plastic is so ubiquitous that it’s almost invisible...
There’ll likely still be applications that really need petroplastic, so landfills will become goldmines. The characteristic drawback of plastic, its stubborn resistance to degradation (‘this plastic bag will still be around in ten thousand years!’) will become a virtue, as it sits unchanged in anaerobic landfills waiting for us to decide that it’s worth excavating and recycling. And one day we’ll do just that–there’ll come a point when the easy, albeit expensive, way to get a particular combination of properties (formability, degradation resistance, sterilisability) will be to dig up post-consumer plastics and reuse them.

Uganda is so poor that few can afford medical care, giving it one of the lowest life-expectancies on the planet — this toxic combination made the country ripe for infiltration by Tiens, a Chinese Multi-Level-Marketing “nutritional supplements” cult whose members set up fake medical clinics that diagnose fake ailments and proscribe fake medicines, then rope […]
Yahoo’s sale to Verizon means that Yahoo’s sub-companies — Flickr, Tumblr and a host of others — are now divisions of a phone company, and as you might expect, being on the payroll of a notorious neutracidal maniac with a long history of sleazy, invasive, privacy-destroying, monopolistic, deceptive, anti-competitive, scumbag shakedowns has changed the public […]

Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
