All the Plastic Ever Produced, Visualized

Humanity has a plastic problem. The cheap, durable material has become a vital part of our vehicles, food packaging, and even the inner structures of our homes. We’ve already produced 8.3 billion metric tons of the stuff, and most of it is sitting in landfills where it could take centuries to break down.

In early 2017, a study published in the journal Science Advances highlighted the literal weight of this growing issue. Researchers calculated that the bulk of all the plastic that’s been made by humans is equivalent to that of 25,000 Empire State Buildings or 80 million blue whales. Of that, only 9 percent has been recycled. The amount of plastic waste currently trashing our planet adds up to 6.3 billion metric tons, and the researchers don’t see our plastic addiction getting any less severe in the near future. By 2050, the plastic in our landfills is expected to hit 12 billion metric tons. You can see more alarming statistics from the study in the infographic below.

Of all the trash we produce, plastic is some of the toughest to get rid of [PDF]. Scientists are looking into solutions, such as plastic-chomping caterpillars and germs, but for now consumers can do the planet a favor by investing in more reusable goods.

How Common Is Your Birthday? An Interactive Map Can Tell You

by James Hunt

At some point in their life, everyone counts back from their birthday and tries to figure out what anniversary, special occasion, or other excuse might have happened to their parents nine months before they were born. To make this backtracking exercise easier—and give us the chance to do it for a much larger population—data journalist Matt Stiles created an interactive "heat map" showing the most common birthdays in the United States for individuals born between 1994 and 2014.

Click on the map and you'll quickly notice that July, August, and September are by far the most common birth months. It's no surprise that nine months prior you'll find the dark and rainy period of October, November, and December when—to put it delicately—people have to make their own entertainment.

According to Stiles, "People generally seem to have time for baby-making during their time off. Several of the most common birth dates, in September, correspond with average conception periods around Christmas. September 9 is most common in this dataset, though other days in that month are close. September 19 is second. Following a customary gestation period, many of these babies would, in theory, have been conceived on December 17 and December 27, respectively."

But that's not all we can tell from the chart. When you take into account the fact that some people get to choose their child's birthday because of induced and elective births, they tend to want to stay away from the hospital during understaffed holiday periods.

"The least common birthdays in this dataset were Christmas Eve, Christmas [Day], and New Year’s Day," Stiles concluded. "Dates around Thanksgiving aren’t as common. July 4 is also at the bottom of the list. Conversely, Valentine’s Day ranks relatively high, as you can see in the graphic, as are the days just before a new tax year begins."

Amazingly, though it only comes around every four years, Leap Year babies aren't as uncommon as you might think: February 29 ranked 347th out of 366 on the list.

Being cursed with a bad memory can yield snafus big and small, from forgetting your gym locker combination to routinely blowing deadlines. If your New Year's resolution was to be less forgetful in 2018, it's time to start training your brain. The infographic below, created by financial website Quid Corner and spotted by Lifehacker Australia, lists seven easy ways to boost memory retention.

Different techniques can be applied to different scenarios, whether you're preparing for a speech or simply trying to recall someone's phone number. For example, if you're trying to learn a language, try writing down words and phrases, as this activates your brain into paying more attention. "Chunking," or separating long digit strings into shorter units, is a helpful hack for memorizing number sequences. And those with a poetic bent can translate information into rhymes, as this helps our brains break down and retain sound structures.
