Why Do Canadians Drink Milk in Bags?

Take a walk through any Ontario-area grocery store and you'll see something a little unusual: shoppers hefting an item into their cart that looks like a plastic package of diapers, weighs roughly nine pounds, and requires some minor effort to enjoy.

It’s a large, tasty bag of milk.

Actually, it’s three medium-sized bladders of milk, packaged together in one large sack. At home, the milk is placed in a pitcher and one corner of the polyethylene plastic is snipped off with scissors for pouring. (Some Canadians snip a second, smaller hole to let air out.) Because it’s not fully sealed, the milk needs to be enjoyed relatively quickly.

For dairy enthusiasts used to the convenience of a resealable container, all of this might seem unnecessary—yet at least 75 percent of all milk sold in Ontario comes in this unique delivery system. The bags of milk can also be found in Quebec and the Maritimes. 

Why? Thank the metric system.

By the late 1960s, glass bottles were still being used for milk, but officials knew they were causing a considerable amount of waste and expense: The heavy bottles were a pain to transport and broke easily. A few years later, Canada was busy converting to the metric system, requiring liquids to be sold in liters. Manufacturing plants producing plastic jugs or cartons (which had debuted around 1915) found that their machines would have to be dramatically altered to allow their containers to be re-sized to meet the new requirements. But the process for injecting milk into plastic bags, which were introduced by DuPont in the late 1960s [PDF], needed only minor tweaks. The bags also produced less packaging waste, since they require less plastic to hold the same amount of milk. Suddenly, pouring milk into giant, floppy sacks seemed like the most obvious thing in the world.

By the early 1980s, the metric system was fully adopted in Canada; in 1978, 4-liter packages of milk became the norm in Ontario [PDF]. Buying bagged became habitual for shoppers, who realized that some of the perceived drawbacks were actually beneficial. Sure, the milk could lose its freshness quickly, but because the packaging was broken up into three bags, there was always a new one to open; unused bags could be stored horizontally in refrigerators in spots where a tall jug wouldn’t fit.

While the unusual packaging confuses even Canadians in other parts of the country, it’s slowly been gaining support in other parts of the world. UK-based Sainsbury’s rolled out two-pint bags around 2010, offering a free pitcher as an incentive for people to make the switch and cut down on waste. Some schools, like Golden Hills Elementary near Omaha, Nebraska, let kids sip from tiny, Capri Sun-esque milk pouches. You can also find them in South Africa, Hungary, and China, which also happens to traffic in bagged beer.

Not planning on traveling outside the country? Try hitting up a Kwik Trip or Kwik Star convenience store, where locations in Wisconsin, Minnesota, and Iowa sell bagged milk by the half-gallon. Though they caution first-timers might need to get used to the pouring technique—there’s apparently a learning curve—they promise customers “will grow to appreciate” the lactose customs of other parts of the world.

Why Do We Dive With Sharks But Not Crocodiles?

Why do we dive with sharks but not crocodiles?

Eli Rosenberg:

The issue is the assumption that sharks' instincts are stronger and more basic.

There are a couple of reasons swimming with sharks is safer:

1. Most sharks do not like the way people taste. They expect their prey to taste a certain way, like fish/seal, and we do not taste like that. Sharks also do not like the sensation of eating people. Bigger sharks like great whites enjoy prey with a high fat-bone ratio like seals. Smaller sharks enjoy eating fish, which they can gobble in one bite. So, while they might bite us, they pretty quickly decide “That’s not for me” and swim away. There is only one shark that doesn’t really care about humans tasting icky: that shark is our good friend the tiger shark. He is one of the most dangerous species because of his nondiscriminatory taste (he’s called the garbage can of the sea)!

2. Sharks are not animals that enjoy a fight. Our big friend the great white enjoys ambushing seals. This sneak attack is why it sometimes mistakes people for seals or sea turtles. Sharks do not need to fight for food. The vast majority of sharks species are not territorial (some are, like the blacktip and bull). The ones that are territorial tend to be the more aggressive species that are more dangerous to dive with.

3. Sharks attacked about 81 people in 2016, according to the University of Florida. Only four were fatal. Most were surfers.

4. Meanwhile, this is the saltwater crocodile. The saltwater crocodile is not a big, fishy friend, like the shark. He is an opportunistic, aggressive, giant beast.


5. Crocodiles attack hundreds to thousands of people every single year. Depending on the species, one-third to one-half are fatal. You have a better chance of survival if you played Russian roulette.

6. The Death Roll. When a crocodile wants to kill something big, the crocodile grabs it and rolls. This drowns and disorients the victim (you). Here is a PG video of the death roll. (There is also a video on YouTube in which a man stuck his arm into an alligator’s mouth and he death rolled. You don’t want to see what happened.)

7. Remember how the shark doesn’t want to eat you or fight you? This primordial beast will eat you and enjoy it. There is a crocodile dubbed Gustave, who has allegedly killed around 300 people. (I personally believe 300 is a hyped number and the true number might be around 100, but yikes, that’s a lot). Gustave has reportedly killed people for funsies. He’s killed them and gone back to his business. So maybe they won’t even eat you.


8. Sharks are mostly predictable. Crocodiles are completely unpredictable.

9. Are you in the water or by the edge of the water? You are fair game to a crocodile.

10. Crocodiles have been known to hang out together. The friend group that murders together eats together. Basks of crocodiles have even murdered hippopotamuses, the murder river horse. Do you think you don't look like an appetizer?

11. Wow, look at this. This blacktip swims among the beautiful coral, surrounded by crystal clear waters and staggering biodiversity. I want to swim there!

Oh wow, such mud. I can’t say I feel the urge to take a dip. (Thanks to all who pointed this out!)

12. This is not swimming with the crocodiles. More like a 3D aquarium.

Big Questions
Can You Expel a Sitting Senator?

In light of recent allegations, Republican Senator Cory Gardner of Colorado this week said that if Alabama Senate candidate Roy Moore “refuses to withdraw and wins, the Senate should vote to expel him, because he does not meet the ethical and moral requirements of the United States Senate.” Meanwhile, Senator Bob Menendez, Democrat of New Jersey, has been involved in a high profile corruption trial, with calls that he should resign or be expelled if convicted. Has anything this drastic ever happened before?

Yes, but not for a very long time. Once you’ve been voted into the Senate, it’s difficult to get you out.

REFUSING TO SEAT

Refusing to even seat a senator is very rare, but one example from over 100 years ago also involved Alabama.

In 1913, Alabama Senator Joseph F. Johnston died just a few months after the ratification of the 17th Amendment to the Constitution. The Amendment allowed for direct election of senators, as well as clarifying the role of the state in calling special elections. Alabama’s governor put up Representative Henry Clayton, but he soon resigned the appointment. This was followed by Frank Glass, a local newspaper editor. As Glass was about to be seated, senators worried that his appointment was illegitimate (similar fears had surrounded Clayton). As one senator said at the time, “I believe that the [17th] Amendment means exactly what it says. It is perfectly plain and unambiguous. It simply means from this time forward every senator of the United States must be elected by the people, unless the legislature of a state by express terms empowers the executive to make temporary appointments to fill vacancies. The legislature of the state of Alabama has not given such power to the executive.”

By a vote of 32-31, the rest of the Senate agreed and refused to seat Glass, leading to a special election in 1914 that brought in a new senator.

Since then there have been multiple attempts to not seat a senator—most famously Roland Burris in 2009, who was appointed by Illinois governor Rod Blagojevich under the cloud of corruption charges (though he was ultimately let in). But in reality a refusal to seat a senator is unlikely to succeed.

In 1969, the Supreme Court ruled in Powell v. McCormack that as long as a duly elected representative met the age, citizenship, and residence requirements of the Constitution, they could not be excluded from the House. They could be expelled after taking their seat, but not excluded. Since it’s generally felt that this ruling extends to the Senate, it would likely not be possible to exclude an elected senator from their seat. But once that seat is taken, expulsion becomes a possibility.

EXPULSION

The United States Constitution states that, “Each House may determine the Rules of its proceedings, punish its members for disorderly behavior, and, with the concurrence of two-thirds, expel a member.” However, this is exceedingly rare.

The first time it happened was in the 1797 case of William Blount, one of the first two senators from Tennessee. According to the Senate, Blount had worked on a plan to take control of Spanish Florida and Louisiana and transfer them to the British with the help of Native Americans and frontiersmen. This plot was discovered and Blount was expelled, but not until he was impeached by the House of Representatives (the House has the sole power of impeachment, and it falls to the Senate to try the impeachment). The Senate ultimately decided not to try the impeachment, although whether that’s because senators believed that they themselves are unimpeachable or because Blount was unimpeachable because he had already been expelled and thus ceased being a senator is up for debate.

The next attempt at expulsion was in 1808, when Ohio’s John Smith was caught up in the Aaron Burr controversies. When it came to vote, the tally was 19 yeas for expulsion and 10 nays. Since the Constitution requires a two-thirds majority, Smith was saved from expulsion by one vote, although he would resign soon after.

The largest crop of expulsions was in 1861 and 1862, in regards to senators from southern states. As some senators were still officially members of the Senate, despite representing seceding states, it was felt that their status should be clarified by expulsion. As a result, 10 senators were expelled on July 11, 1861 (the expulsion order of one of the senators, William K. Sebastian of Arkansas, was later posthumously revoked after it was determined the charges “were as regards Sebastian merely a matter of suspicion and inference and wholly unfounded as to fact” and he didn’t commit conspiracy against the government). Later, a few more senators were expelled on the charge of supporting the rebellion. Including Sebastian, a grand total of 14 senators would be expelled during the Civil War. Since then, no senator has been expelled.

That’s not to say there haven’t been attempts. Cases since the Civil War have ended in either an exoneration or the senator leaving office before the vote. The most recent near-expulsion was Nevada Senator John Ensign in 2011 under accusations that he broke federal laws while attempting to cover up an affair. At the time, Senator Barbara Boxer of California said the case was “substantial enough to warrant the consideration of expulsion.” Ultimately, Ensign resigned.

It has been 155 years since the last senator was expelled. Whether—or when—that fact will change only time will tell.
