Sailors have been circumnavigating the high seas for centuries now, but what could be found beneath the sunlit surface of the ocean remained a mystery until far more recently. In fact, it wasn’t until 1875, during the Challenger expedition, that humanity got it’s first concrete idea of how deep the ocean actually was.

Today’s graphic, another fantastic piece by xkcd, is a unique and entertaining look at everything from Lake Superior’s ice encrusted shoreline down to blackest, inhospitable trench (which today bears the name of the expedition that first discovered it).

The graphic is packed with detail, so we’ll only highlight a few points of interest.

Deep Thoughts with Lake Baikal

Deep in Siberia, abutting a mountainous stretch of the Mongolian border, is the one of the most remarkable bodies of water on Earth: Lake Baikal. There are a number of qualities that make Lake Baikal stand out.

Depth: Baikal, located in a massive continental rift, is the deepest lake in the world at 1,642m (5,387ft). That extreme depth holds a lot of fresh water. In fact, an estimated 22% of all the world’s fresh water can be found in the lake.

Age: Baikal (which is listed as a UNESCO World Heritage Site) is estimated to be over 25 million years old, making it the most ancient lake on the planet.

Clarity: Interestingly, the water in the lake is exceptionally clear. In winter, visibility can extend over 30m (98ft) below the surface.

Biodiversity: The unique ecosystem of Lake Baikal provides a home for thousands of plant and animal species. In fact, upwards of 80% of those species are endemic, meaning they are unique to that region.

Who is Alvin?

Since 1964, a hard-working research submersible named Alvin has been helping us better understand the deep ocean. Alvin explored the wreckage of RMS Titanic in 1986, and helped confirm the existence of black smokers (one of the weirdest ecosystems in the world).

Though most of the components of the vessel have been replaced and upgraded over the years, it’s still in use today. In 2020, Alvin received an $8 million upgrade, and is now capable of exploring 99% of the ocean floor.

The Ocean’s Deepest Point

The deepest point in the ocean is the Mariana Trench, at 11,034 meters (36,201 feet).

This trench is located in the Pacific Ocean, near Guam and the trench’s namesake, the Mariana Islands. While the trench is the most extreme example of ocean depths, when compared to surface level distance, it’s depth is shorter than Manhattan.

Mariana trench depth compared to cities

Obviously, the context of surface distance is wildly different than vertical distance, but it serves as a reminder of how narrow the “explorable” band of the Earth’s surface is.

Polymetallic Nodules

The ancient Greek word, ábyssos, roughly means “unfathomable, bottomless gulf”. While there is a bottom (the abyssopelagic zone comprises around 75% of the ocean floor), the enormous scale of this ecosystem is certainly unfathomable.

Objectively, the abyssal plain is not the prettiest part of the ocean. It’s nearly featureless, and lacks the panache of, say, a coral reef, but there are still some very compelling reasons we’re eager to explore it. Resource companies are chiefly interested in polymetallic nodules, which are essentially rich manganese formations scattered about on the sea bottom.

Manganese is already essential in steel production, but demand is also getting a substantial lift from the fast-growing electric vehicle market. The first company to find an economical way to harvest nodules from the ocean floor could reap a significant windfall.

Drill Baby, Drill

Demand for resources can force humans into some very inhospitable places, and in the case of Deepwater Horizon, we chased oil to a depth even surpassing the famed Marianas Trench.

Drilling that far below the surface is a complicated endeavor, and when the drill platform was put into service in 2001, it was hailed as an engineering marvel. To this day, Deepwater Horizon holds the record for the deepest offshore hole ever made.

After the rig’s infamous explosion and subsequent spill in 2010, that depth record for drilling may stand the test of time.

33 Problems With Media in One Chart

In this infographic, we catalog 33 problems with the social and mass media ecosystem.

33 Problems With Media in One Chart

One of the hallmarks of democratic society is a healthy, free-flowing media ecosystem.

In times past, that media ecosystem would include various mass media outlets, from newspapers to cable TV networks. Today, the internet and social media platforms have greatly expanded the scope and reach of communication within society.

Of course, journalism plays a key role within that ecosystem. High quality journalism and the unprecedented transparency of social media keeps power structures in check—and sometimes, these forces can drive genuine societal change. Reporters bring us news from the front lines of conflict, and uncover hard truths through investigative journalism.

That said, these positive impacts are sometimes overshadowed by harmful practices and negative externalities occurring in the media ecosystem.

The graphic above is an attempt to catalog problems within the media ecosystem as a basis for discussion. Many of the problems are easy to understand once they’re identified. However, in some cases, there is an interplay between these issues that is worth digging into. Below are a few of those instances.

Editor’s note: For a full list of sources, please go to the end of this article. If we missed a problem, let us know!

Explicit Bias vs. Implicit Bias

Broadly speaking, bias in media breaks down into two types: explicit and implicit.

Publishers with explicit biases will overtly dictate the types of stories that are covered in their publications and control the framing of those stories. They usually have a political or ideological leaning, and these outlets will use narrative fallacies or false balance in an effort to push their own agenda.

Unintentional filtering or skewing of information is referred to as implicit bias, and this can manifest in a few different ways. For example, a publication may turn a blind eye to a topic or issue because it would paint an advertiser in a bad light. These are called no fly zones, and given the financial struggles of the news industry, these no fly zones are becoming increasingly treacherous territory.

Misinformation vs. Disinformation

Both of these terms imply that information being shared is not factually sound. The key difference is that misinformation is unintentional, and disinformation is deliberately created to deceive people.

Fake news stories, and concepts like deepfakes, fall into the latter category. We broke down the entire spectrum of fake news and how to spot it, in a previous infographic.

Simplify, Simplify

Mass media and social feeds are the ultimate Darwinistic scenario for ideas.

Through social media, stories are shared widely by many participants, and the most compelling framing usually wins out. More often than not, it’s the pithy, provocative posts that spread the furthest. This process strips context away from an idea, potentially warping its meaning.

Video clips shared on social platforms are a prime example of context stripping in action. An (often shocking) event occurs, and it generates a massive amount of discussion despite the complete lack of context.

This unintentionally encourages viewers to stereotype the persons in the video and bring our own preconceived ideas to the table to help fill in the gaps.

Members of the media are also looking for punchy story angles to capture attention and prove the point they’re making in an article. This can lead to cherrypicking facts and ideas. Cherrypicking is especially problematic because the facts are often correct, so they make sense at face value, however, they lack important context.

Simplified models of the world make for compelling narratives, like good-vs-evil, but situations are often far more complex than what meets the eye.

The News Media Squeeze

It’s no secret that journalism is facing lean times. Newsrooms are operating with much smaller teams and budgets, and one result is ‘churnalism’. This term refers to the practice of publishing articles directly from wire services and public relations releases.

Churnalism not only replaces more rigorous forms of reporting—but also acts as an avenue for advertising and propaganda that is harder to distinguish from the news.

The increased sense of urgency to drive revenue is causing other problems as well. High-quality content is increasingly being hidden behind paywalls.

The end result is a two-tiered system, with subscribers receiving thoughtful, high-quality news, and everyone else accessing shallow or sensationalized content. That everyone else isn’t just people with lower incomes, it also largely includes younger people. The average age of today’s paid news subscriber is 50 years old, raising questions about the future of the subscription business model.

For outlets that rely on advertising, desperate times have called for desperate measures. User experience has taken a backseat to ad impressions, with ad clutter (e.g. auto-play videos, pop-ups, and prompts) interrupting content at every turn. Meanwhile, in the background, third-party trackers are still watching your every digital move, despite all the privacy opt-in prompts.

How Can We Fix the Problems with Media?

With great influence comes great responsibility. There is no easy fix to the issues that plague news and social media. But the first step is identifying these issues, and talking about them.

The more media literate we collectively become, the better equipped we will be to reform these broken systems, and push for accuracy and transparency in the communication channels that bind society together.

Visualizing the Current State of the Global Gender Gap

At our current rate of change, it will take up to 136 years to close the global gender gap. Here’s a look at gender inequality across regions.

Map showing gender gaps in each region

The Current State of the Global Gender Gap

As a global society, we still have a long way to go before we reach gender equality around the world.

According to the World Economic Forum’s (WEF) latest Global Gender Gap Report, it could take up to 135.6 years to close the global gender gap, based on the current rate of change.

This graphic by Sebastian Gräff gives a breakdown of gender equality worldwide, showing how long it will take before each region reaches gender parity.

How Gender Gap is Measured

In its 15th edition, the Global Gender Gap Report analyzes gender-based discrepancies across 156 different countries. To gauge each region’s gender gap, the report digs into four key areas:

  1. Economic Participation and Opportunity
  2. Educational Attainment
  3. Health and Survival
  4. Political Empowerment

Each subindex is given its own score, then an average across the four pillars is calculated to give each country a final score between zero (exceptionally unequal) and one (completely equal).

Regional Breakdown

Out of all the regions, Western Europe has the smallest gender gap, with a score of 0.78. At this rate, the gender gap in Western Europe could be closed in approximately 52.1 years, more than 83 years faster than the global estimate.

RankRegionOverall Gender Gap Index (2021)
1Western Europe0.77
2North America0.76
3Latin America and the Caribbean0.71
4Eastern Europe and Central Asia0.71
5East Asia and the Pacific0.69
6Sub-Saharan Africa0.67
7South Asia0.62
8Middle East and North Africa0.61
Global Average0.69

Western Europe scores particularly high in educational attainment (1.0) and health and survival (0.97). Here’s a look at the category breakdown for each region:

RegionEconomic Participation and OpportunityEducational AttainmentHealth and SurvivalPolitical Empowerment
Western Europe0.701.000.970.44
North America0.751.000.970.33
Latin America and the Caribbean0.641.000.980.27
Eastern Europe and Central Asia0.741.000.980.14
East Asia and the Pacific0.700.980.950.14
Sub-Saharan Africa0.660.850.970.21
South Asia0.340.930.940.28
Middle East and North Africa0.410.940.970.12
Global Average0.620.960.970.22

But it might be surprising to see that political empowerment in Western Europe received a score of only 0.44. This is higher than the global average for political empowerment of 0.21, but still indicative of a large gender gap in this area.

Globally, political empowerment tended to receive the lowest scores in the report, as women are grossly underrepresented in politics. A study by the Council of Foreign Relations revealed that out of 195 different countries’ national cabinets, only 14 countries had at least 50% of their ministerial positions held by women.

Economic participation and opportunity is the second weakest category, with a global average score of 0.58. A good example of how this gap manifests itself is in entrepreneurship and business, where women still struggle to find investors and gain access to venture capital. Further, on average, women continue to make less money than men. According to the UN, women across the globe make approximately 77 cents for every dollar earned by men.

The Economic Benefit of Gender Equality

Research shows that empowering women in the workforce is in everyone’s best interest. Closing the gender gap in the global workforce could lead to a boost of more than $28 trillion to the global economy.

Yet across the globe, COVID-19 has created new challenges that have hindered our progress towards gender equality. This is partly because some of the sectors that have been impacted the most by COVID-19 restrictions, such as hospitality, food services, and personal care, are largely dominated by female workers.

As we continue to recover from the impact of COVID-19, world leaders will face numerous policy challenges, including how to build back better, creating more opportunities for women to thrive in the global economy.
