The Extinction Rate is Much Higher Than the Natural Baseline Rate

Super fact 71 : Based on the fossil record today’s extinction rate is hundreds, or even thousands, of times higher than the natural baseline rate.

Estimating the extinction rate is a complicated task that requires some assumptions and estimations. This article from the National Library of Medicine use what it claims to be conservative estimates, which would tend to minimize evidence of an emerging mass extinction. Despite that fact the average rate of vertebrate species loss over the last century is up to 100 times higher than the extinction rate without/before humans (background rate). Other sources claim an extinction rate that is 1,000 or even 10,000 the background rate.

To put some specific numbers on what a high extinction rate means, scientists count 881 animal species are known to have gone extinct since around 1500. If we include animal species that scientists suspect might be extinct, that number shoots up to 1,473. You can read more on the issue here or here or here.

What is clear is that the current extinction rate is much higher than what is typical and we humans are the cause. This came as a shock to me the first time I found out about it, and it is certainly an important topic, and therefore a super fact. It is true, surprising to many, and important.

Those who want to minimize the problem with the ongoing extinctions often point out that extinctions are a natural part of evolution and that throughout Earth’s history up to around 98% of all species that have ever existed are now extinct. In my opinion, that argument fails to consider the enormity of Earth’s four billion year natural history. A lot of evolution happened during that time.

Modern humans have only been around 300,000 years, or 0.0075% of that time, a tiny blip in time. Human civilization has only been around for 12,000 years, or 0.0003% of that time, an even tinier blip in time. Like comparing an ant head to a mile. Us having a large negative impact on the natural world in such an extremely short time is quite notable.

By considering the extinction rate you get a better idea of the scope of the problem. The fact that the extinction rate today is significantly higher than the expected natural rate and that the primary cause of modern extinctions is human impact as opposed to natural phenomena, makes it a case for concern.

The Five Past Mass Extinction Events

Over the last 440 million years life on Earth has experienced five so called mass extinctions. A mass extinction event is when at least 75% of the world’s species are lost during a short period of time – geologically speaking. This period is not clearly defined but often defined to be two million years. Two million years may seem like a long time, but geologically speaking, it is a short time.

The graph shows extinction rates going up and down with five tall peaks representing mass extinction events.
The Big Five Mass Extinctions in Earth’s History. A mass extinction is defined by the loss of at least 75% of species within a short period of time (geologically, this is around 2 million years). Extinctions are a natural part of evolution, but background rates are typically less than 5 families extinct per million years. Sources Barnosky et al (2011).

Biodiversity experts have estimated that about 30% (uncertainty range: 16–50%) of species have been globally threatened or driven to extinction since the year 1500. 30% globally threatened or extinct is not 75% that are actually extinct, but in just 500 years that looks like a quick start on a mass extinction. It should be noted that 500 years is just 0.025% of two million years. Issues such as deforestation, chiefly the result of replacing forests with agriculture, overexploitation, and global warming / climate change are driving extinctions and represent big biodiversity threats in the near future.

This is why there is talk about the so called Holocene or Anthropocene extinction and it possibly being a sixth mass extinction, this one being human caused. It should be noted that there are credible sources that question whether we are at the cusp of a sixth mass extinction event.

Posting this on Thanksgiving Day may seem awkward. However, whether there will be a human caused sixth mass extinction or not depends on us, and it looks like more people want to protect our natural world. Many animals, such as the giant panda, bald eagle, the sea otter, black footed ferret, the Peregrine falcon, the blue whale, Rodrigues fruit bat, the Island night lizard, and the California condor, have been saved from extinction through conservation efforts like habitat restoration, anti-poaching laws, captive breeding programs, and reintroduction to the wild. Perhaps we are turning things around. We should give thanks to all who care.

The Wild Mammal Biomass Has Substantially Declined

Super fact 70 : Wild mammals have declined by 85% since the rise of humans even as the total mammal biomass has nearly tripled. The result is that only 4-5% of the total biomass of mammals are wild animals. The rest are humans and livestock.

Pie chart shows that Livestock, mostly cattle and pigs, corresponds to 60% of the mammal biomass, humans are 36%, and wild mammals are 4%. | The Wild Mammal Biomass Has Substantially Declined
Livestock, mostly cattle and pigs, corresponds to 60% of the mammal biomass, humans are 36%, and wild mammals are 4%. The data is taken from this article.

As stated, mammal biomass has declined by 85% since the rise of humans. This is despite a threefold increase in mammal biomass over the last 200 years. However, this increase is almost entirely due to the growth of human and livestock populations. The result is that only 4-5% of the total biomass of mammals are wild animals. Another result is that Earth’s wild land mammals now make up just 2% of the mammal kingdom. You can read more here, or here, or here, and more in depth here.

Humans are 36% of the mammal biomass, Sheep is 4%, Livestock and pets 59%, including 2% dogs, 3% pigs, goats 3%, cattle 38%, and buffalo 6%
Humans and our livestock dominate global mammal biomass. Biomass is the total weight of each animal group. It’s calculated by multiplying an estimate of the total number of individuals by their average mass. Shown is each group’s share of global mammal biomass. This graph is taken from Our World In Data.

I think this is a super fact because we know it is true, and this huge and extremely rapid change of Earth’s fauna (from a geological timescale) is certainly important, and yet I think it comes as a surprise to many people. I often see the argument that humans have been great for animals because there are many more of them and the mammal biomass has tripled. That argument leaves out the part about the increase in mammal biomass coming from domesticated animals while wild animals have been disappearing. One question that comes to mind is whether life at the cramped factory farm is better than the life as a wild animal.

Wild Mammal Biomass Data

Below are a couple of graphs displaying some additional information on wild mammal biomass.

The graph shows that even hoofed mammals is a big group consisting of 49% of the wild mammal biomass. Rodents are 16% and elephants are 8%, bats are 7%, Marsupials are 7%, and primates are 4%, carnivores 3%, rabbits 1%, and other mammals 4%.
The distribution of the world’s wild land mammal biomass. The graph is taken from Our World in Data.

Another thing to note is that the wild animal biomass is very concentrated to just a few species. Considering that there are between 6,500 and 6,800 recognized mammal species in the world, it is quite remarkable that only 10 species make up 40% of the mammal biomass.

White-tailed deer is 12%, Wild boar is 8%, African Savanna Elephant is 6%, Eastern gray kangaroo is 2%, Mule deer is 2%, Moose is 2%, Red Deer is 2%, European roe deer is 1.8%, Red Kangaroo is 1.8%, and the Common Warthog is 1.4%.| The Wild Mammal Biomass Has Substantially Declined
Just 10 species make up around 40% of wild mammal biomass on land. The graph is taken from Our World in Data.

Reasons for Decline of Wild Animal Biomass

This decline of wild mammal biomass is primarily caused by human activity, including hunting, habitat loss and degradation from agriculture and urbanization, climate change, and pollution. This human-driven extinction event is the result of a rapidly growing human population and its increased consumption of natural resources, leading to widespread disruption of ecosystems and dramatic declines in wild mammal populations. It should be mentioned that the extinction of large mammals such as mammoths, American mastodon, giant ground sloths and glyptodonts was likely aided by human hunting in prehistoric times. The largest mammals have always been at the greatest risk for extinction and that is still true today.

Polar Nights Are Phenomenal and Cover a Large Area

Super fact 69 : Polar nights happen in the regions north of the Arctic Circle and south of the Antarctic Circle. Together the two polar regions cover an area double as large as the United States, and it includes a population of millions of people. During a polar night the sun does not rise for days, or months, up to six months.  The polar nights are special, not just for the daytime darkness, but for the spectacular aurora borealis, the starlit skies, the extremely clear air, and the fact that people often lose track of time during polar nights.

It should be noted that even though the sun never rises during the polar night it may not be totally dark during the entire polar night. Part of the time you may get some light in the middle of the day, what is called polar twilight (nautical twilight or astronomical twilight). Nautical twilight tends to be bluish as shown in the photo below.

When our kids were young, we visited the Ice Hotel in Jukkasjärvi in northern Sweden. We went in March, during the American spring break, which was not during the polar night, so we did not experience it then. The polar night in Jukkasjärvi will begin December 5, 2025, or December 10, 2025, depending on how you count, and end at the beginning of January. However, the Ice Hotel was a fun way to experience a polar region. When I did my Swedish army service I spent the winter in the forest around that area, and even further north, and I experienced the Polar Night firsthand,

The lobby of the ice hotel. Our kids are sitting around a table of ice. A chandelier of ice is hanging above the table. The light is from fiber optics, so the ice won’t melt.

During my army service we stayed in tents in the forest far away from villages and cities and we often did not use any lights. The result was that it was incredibly dark most of the time. It was so dark that I could not see my own hand if I held it right in front of my face. The upside was that the sky was filled with thousands of stars on a clear night. It is estimated that you can see between 2,500 to 5,000, even 10,000, stars in the sky with the naked eye if you have good vision and it is completely dark. You could also see the Milky Way Galaxy very clearly and easily, as well as the Andromeda Galaxy, meteors, comets, satellites, not to mention the most spectacular aurora borealis that you can see anywhere on earth. That certainly beats the 14 stars and 3 planets that you can see with the naked eye on a clear night here in Dallas, Texas, where I live now.

On one occasion I was standing guard outside the camp. We were pretending that we were at war with the Soviet Union. It was minus 40 degrees, and they forgot about me. I stood there alone in the darkness and the extreme cold for more than three hours. This was considered dangerous. The rule was no more than one hour out in the cold at a time. Once they discovered that I had been there for more than three hours they came to get me, and they apologized profusely. They were happy that I was not hurt. However, I did not mind, because my night sky view was spectacular. The night sky was so spectacular, it was to die for.

If it is cloudy and you are far from any civilization it may be pitch black in the afternoon. Even if it is not cloudy but the moon is not out it will be pitch black later in the afternoon. In addition, the air is very clear during the polar night, because the cold sunless Arctic air often contains almost no moisture and the visibility stretches for 100 miles. If you want to remain unseen in this situation it is very important to understand that even the tiniest light will be very visible, far away.  Our platoon did an experiment. Someone lit a cigarette about one mile away and we could very easily see the bright cigarette even through the forest. The lesson was, No Cigarettes, and No lights!

I consider this a super fact because the polar night is a surprising phenomenon to those who do not know much about the arctic and my claims above are true and important since the polar regions are large and under threat from climate change / global warming.  The polar regions and thereby the polar night also cover an area that is not small, and four million people live there.

The Midnight Sun

I can add that in the summer (northern hemisphere) you have the opposite phenomenon with the midnight sun. Just like the polar night can cause people to lose track of time so can the midnight sun. When we visited northern Sweden with our niece Jessica for my brother’s wedding, we had what is called midnight sun. Jessica was nine years old at the time. A couple of hours after we had gone to sleep Jessica woke me up “wake up Thomas, it is time to go out and play”. I protested, no it is not, it is one a clock at night and we are going to sleep. Jessica protested, she said, “No the sun is up, it is morning it is time to play”.

So, I said “Jessica, let me explain something to you. This is northern Sweden in June and here the sun is up in the middle of the night, and we are not going outside to play in the middle of the night.” After that my wife went out to play with Jessica, but I refused to go out and play at one o clock at night.

Ice Hotel Photos

Finally, I just wanted to include a few of my photos from the Ice Hotel, just for fun.

Infinities Come in Different Sizes

Super fact 68 : Infinities come in different sizes. Some infinities are larger than others. In fact, it is possible to create an infinite number of different-sized infinities. Some infinities are countable and others are uncountable.

How can infinity be of different sizes? Infinity is infinity after all. Infinity is an absolute, an absolute we cannot imagine. However, at the end of the 19th century a German mathematician by the name Georg Cantor demonstrated that there exists a variety of infinities, and some are larger than others. In fact, his theorem implies the existence of an infinity of infinities. For those who have not heard of this concept before it is surprising and yet it is true, and it is also kind of an important thing to know about mathematics. This is why I consider this a super fact.

Let me explain. Think about all natural numbers, 1, 2, 3, 4, 5, …, a billion, a quintillion, … You can keep counting forever. There are infinitely many natural numbers. Now take two natural numbers, the numbers 3 and 4. How many numbers are in between 3 and 4? Well, you have 3.5, 3.55555, 3.016893, and you have the number pi, 3.14159265358979323846, and infinitely many other numbers with infinitely many decimals. 3 and 4 are only two numbers but you have infinitely many decimal numbers, or so called real numbers, between 3 and 4. That is true for the two numbers 4 and 5 as well, and 5 and 6, and all natural numbers. Even though there are infinitely many natural numbers there are infinitely many more real numbers.

For the explanation of the mathematical proof see this article in Scientific American. This article explains why there are an infinite number of different-sized infinities.

I should say that today Saturday November 8, 2025, is National STEM Day, or STEAM Day. Stem stands for Science, Technology, Engineering, and Mathematics. The extra ‘A’ in STEAM stands for Art. Therefore, I thought that posting something related was appropriate for today, in this case it is Mathematics. I have to admit I am posting it a little bit late in the day though.

To infinity … and beyond!

As mentioned, infinites can have different sizes. How about, for example, the set of all natural numbers and the set of even numbers. After all, it seems like the set of all even numbers should be half as big. As it turns out they are the same size. That’s because for all natural numbers 1, 2, 3, 4, 5 you can always find a buddy, 2, 4, 6, 8, 10 among the even numbers. This is called a bijection. However, you cannot do this with natural numbers versus real numbers. You cannot pair up a natural number with the real numbers because there are infinitely many for each single natural number.

The set of all real numbers is really a larger infinity than natural numbers, which by the way is the smallest infinity. The sets of natural numbers and, for example, even numbers are called countable infinities, and the set of real numbers are called uncountable infinities. In addition, there are infinitely many different sizes of infinities that are larger than both natural numbers and real numbers.

Another interesting, related issue is that Cantor tried to prove that there are no infinities with sizes that lie in between the natural numbers and the real numbers. This was called the continuum hypothesis. As it turned out this hypothesis is not possible to prove (you can prove that it cannot be proved) at the same time as it is not possible to disprove. It is related to Gödels incompleteness theorem but is not the same. However, it is another absolute limit to human knowledge, things we know that we can never know.

More than half of Internet Traffic is Bots

Super fact 66 : Bots make up more than half of all internet traffic surpassing human activity for the first time in 2024. The 2025 Imperva Bad Bot Report found that bots accounted for 51% of all web traffic. Human activity accounted for 49% of all internet traffic, malicious “bad bots” accounted for 37%,  and 14% of traffic comes from “good bots,” such as search engine crawlers.

What made me look up this information is that I’ve recently seen a lot of idiotic and inflammatory comments, as well as inappropriate laughing emojis on social media pages and posts. The pages that seem to be targeted the most by this abuse seems to be pages related to things like climate change, clean energy, EV cars, evolution, vaccines, modern medicine, modern physics, geopolitics, information on political issues, etc. However, those topics might reflect my interests. Perhaps all topics are targeted by this growing strange abuse.

It looks like those among us who slept through the science classes in high school now think they are the real experts and have declared war on all science nerds. The question that arose in my mind is, are these keyboard warriors humans or are they bots? It is true that Artificial Intelligence does not (yet) demonstrate true independent intelligence, but that is true for many people as well. So, how do you know the difference? Anyway, that is the background to why I investigated this issue.

I looked it up and found that bot traffic has been increasing and is now the majority of all internet traffic according to, for example, the 2025 Imperva Bad Bot Report. You can read more here. Facebook is not an exception. 40% of all posts are machine generated. These bots/fake accounts spread a lot of misinformation, inflammatory comments, and some are scams.

Many people are also spreading false information and some of them are scammers, but the fact that machines do it as well add to the problem. It is also very common for bots and fake accounts to leave reactions on Facebook posts, which might be what I saw, but I am not sure. What is certain is that I have come across a lot of false information on Facebook, as well as scams and deep fakes, and Meta/Facebook is obviously not able to clean it out. There are also bots that are remotely controlled ransomware, computer viruses, spyware, and other malware.

Why I consider this a super fact is because it appears to me that people underestimate the influence of malicious bots. If you had asked me before I looked this up how common bot traffic was, I might have said a few percent. After all streaming, youTube, gaming, etc., require a lot of bandwidth. Considering all the fake stuff and nonsense that is spreading partially with the help of bots, this is dangerous. We know the bots make up more than half of all internet traffic, and bot traffic is growing faster than human traffic, it is important information, and I think it is surprising information to a lot of people, thus making it a super fact.

Fake Nonsense on Facebook

This section is not directly tied to the super fact above, but it concerns a related topic and is based on my personal experience with the social media platform that I have used the most, Facebook. Instagram seems to be even worse, but I am not using it as much. Why I am bringing this up is because increased bot traffic and the increased presence of fake accounts and deep fakes on social media can make this a lot worse. Combined with our gullibility and lack of critical thinking as well as the failure of social media platforms to keep after this, we are facing a serious threat.

Gullible Planet

It is well known that there are a lot of nonsense posts on Facebook (and elsewhere). The fact that we so easily fall for it and don’t check with reliable sources is a big problem. When I see something fake, I often post corrections, for example, using sites like snopes. Sometimes people are grateful, sometimes they get angry, and I’ve even been blocked and lost friends just by posting a snopes link. A lot of the fake stuff is posted by people, but a lot of posts, comments and reactions are posted by bots, and this is becoming more common. With increased malicious bot traffic, AI and deep fakes, we must improve our critical thinking skills.

Below are some examples of fake stuff I’ve come across on Facebook

Did you read that viral article on Facebook claiming that they found 20 feet humanoid skeletons in Turkey? The article stated that archeologists think that they might be fossilized Nephilim, the giants mentioned in the Old Testament. If so, did you doubt the accuracy of the article? If you did, you did good. It was based on an article in a satirical website called World News Daily Report. However, judging from the comment section, including the comments of some of my friends, most people didn’t doubt the article’s accuracy.

How about the story from a purported science magazine that scientists had just discovered that the Easter Island statues/heads have bodies/torsos below the ground. The article stated that this was a revolution in archeology that forced a reevaluation of history. The commentors were amazed over this discovery and some pointed out that not realizing this sooner was a big failure on the part of archeologists and scientists. Well, that the Easter Island statues/heads have bodies/torsos below the ground has been known all along.

How about the story about the lunch lady named Aileen G. Ainuse who poisoned the water supply at Sunnydale High School in Goobersville, Indiana, killing over 300 students and staff. It was accompanied by a scary photo of a starving lady. The readers were shocked and appalled, but not many bothered to verify the story, for example, with the help of snopes. The story was false.

Another article stated that the fact that there were no stars in the black sky in a photo allegedly taken on the moon was proof that the photo was fake and that the astronauts were never on the moon. First of all, it was day, the sun was out. When the sun is out it is very difficult to see the stars because the sun’s light is a million times brighter than the light from the stars and in addition the bright sunlight reflected off the surface of the moon dims the stars. In addition, the cameras used had short shutter speeds for picking up the bright light, not faint stars. Seeing stars in a daytime photo taken on the moon is not something you should expect. Several commentors pointed this out but most other commentors didn’t pay attention and were fooled.

I’ve also seen the opposite, people refusing to believe a true story because they fundamentally misunderstand something. Below is a youTube video showing an animation composed of actual satellite photos by NASA. Many commentors seeing this video insisted that it was a hoax because the back side of the moon is dark. But it is not. When the side of the moon that is turned towards us (the near side) is dark (a new moon) the back side reflects the sun’s light (like a full moon). The backside (far side) of the moon also looks different from the side turned towards us. In the video below the sun is behind the camera and shines on earth as well as the backside of the moon.

A final example is a deep fake Ad featuring Meryl Streep and Dr. Sanjay Gupta promoting an Alzheimer’s cure. I saw it on Facebook several times over a period of several weeks. It looked very real to me, but something felt off, so I fact checked. It turned out that Meryl Streep and Sanjay Gupta had nothing to do with the video. They were AI generated likenesses promoting a scam product. The video used all the typical polemic tricks such as “a cure that the billion dollar companies don’t want you to know about”, “buy now before they take our website down”…. We need to get better at protecting ourselves and believing 20 feet skeletons on Facebook are real is not the way to do it.
