The Mystery of the Pink Lake

Over the past few weeks, the internet has been filled with pictures of a mysterious pink lake in the center of Melbourne, Australia. This sparks a question: Are such lakes real? And if they are, how do they become pink? The answer may surprise you.

Those pictures flooding social media are actually real, and it’s completely natural! And they can happen all over the world, too! For this specific lake in Melbourne, it’s an annual occurrence. When the weather gets dry and water starts evaporating, the salinity of the water drastically increases. The result is a lake with salinity levels about ten times higher than the ocean. That’s more salty than the Dead Sea, at nine times higher than ocean water. This makes it almost impossible for any organism to live there. But there is one in particular that stays.

There is a species of algae that loves salt, and also produces carotenoids, or red-colored pigments. When these algae are the only things living in a lake, it’s only a matter of time before the carotenoids fill the lake and give it that hot pink color.

The carotenoid-producing algae live in many lakes all over the world. Most of them aren’t pink though, because they aren’t the only things living in those lakes. One of these is Las Salinas de Torrevieja in Spain, which attracts thousands of flamingos every breeding season. The carotenoids are what make the feathers of flamingos pink, and what makes some brine shrimp pink.

The lakes don’t only have to be pink, though. There are several lakes such as the Laguna Colorada and the Laguna Verde, both part of Eduardo Avaroa Andean Fauna National Reserve in Bolivia, which have many other odd colors, also due to certain algae and minerals in the water. These two, in particular, are blood red and turquoise, respectively.

 

While this lake in Melbourne looks like it would be a blast to swim in, it’s not the best idea. Getting the water in your eyes would feel like soy sauce, and the salt would crystallize right there in your eyes when it dried. Looking at the lake, however, is perfectly fine, and it attracts many tourists. The lake is expected to return to its normal color when the southern hemisphere starts to cool down and get more rain in June.

Pulling out the Trump Card

President Trump shows off his executive order, signed.

President Trump had already written his first executive order before Inauguration Day, ready to be signed as soon as he was sworn in. This is no surprise, though, as Trump was eager to start making America great again as soon as possible. The real surprise was what was written in this executive order. It ordered that all anime must be stripped from store shelves, removed from TV channels, taken down off the internet, and confiscated from all citizens, and that it should be enacted immediately.

The Trump Administration was very quick to enforce it, too. The next day, police officers were going door to door all over the country confiscating any DVDs containing anime, and jailing anyone who refused to give up their prized discs. The amount of jail time earned is not yet decided, but a representative of the Trump Administration said that it could be anywhere between two and five months. A reported 1,337 people were jailed within the first week of the order being enacted.

“I woke up at five in the morning to a loud banging on my door,” says anime enthusiast Jamison Randall. “By the time I got up, officers had busted down the door and were all over my house searching for anime DVDs, and I was held at gunpoint to open my safe. When I opened it, they searched through it, and left everything exactly where it was except for my anime.” Randall also claims that after the anime was confiscated, the officers left his house casually, like nothing ever happened.

Examples like this sparked controversy among citizens, mostly about the harshness of the confiscation. One supporter of the ban even said, “The ban was a good idea, but the way cops are taking anime from homes is over the top.”

The debate about whether or not the ban was a good decision is causing fights all over the country. An estimated 4,200 people have been hospitalized in the past week due to injuries caused by fist fights over this executive order.

It is estimated that about 69% of US citizens agree with Trump’s decision to ban anime. Those who disagree are going to extreme measures to hide their precious anime, doing so much as to hide it in their ceilings. President Trump called for another search to happen this weekend, as he is suspicious of people hiding anime.

Opposers are hoping that the all the protest and violence that happened over the past few weeks because of the order will encourage Trump to revoke the order. Whether or not he will do so is completely unpredictable.

A New Calendar to Show How Far Humans Have Come

If anyone is asked what year it is, they would probably answer “2017.” But our history as humans goes much farther back than the year 0. Humans have existed for millions of years, and we have been making major achievements for thousands. What if we were to make a new calendar to accurately depict the length of our history? If so, where would we place to 0?

“Kurzgesagt – In a Nutshell,” a YouTube channel run by a small group of people dedicated to producing educational “content that has value and that people actually notice and remember,” brought up this idea in a video titled “A New History for Humanity – The Human Era.” However, it has been an idea for over 20 years before this video was released. In 1993, scientist Cesare Emiliani proposed an idea of a new calendar – one that places its first year at the beginning of what he calls the “Human Era,” where we started building our world to suit our needs on top of the existing one, when we turned from hunter-gatherers to farmers. But what event marks the beginning of this “Human Era?”

Remnants of the 12,000 year old temple can still be seen today.

About 12,000 years ago, hundreds of hunter-gatherers came together in the hills of Anatolia, or the area we call Turkey today, and started the world’s first construction project. Göbekli Tepe, which means “Potbelly Hill” in Turkish, was a temple made with circles of huge stone pillars, each being up to six meters tall and weighing approximately twenty tons. They were decorated with carvings of pictograms, some resembling animals and others mythical creatures. These early humans had only wood and stone tools, and knew nothing about metalworking or agriculture. To this day, we have no idea how they built this. It is believed to have been a temple dedicated to long-forgotten gods, but the one thing we know for sure is that this temple was the first of its kind.

From there, humans made huge progress that we seemingly ignore with the Gregorian calendar. It makes our history seem much shorter than it actually is. Thinking about it with this Holocene calendar, 2,000 years is just a sliver of our actual history. So, next time you look at your calendar, consider changing that year to 12,017. Don’t underestimate the extent of human history.
