3. Human hunting played a role in their extinction, but climate change was the main cause.

4. The speed of climate change contributed to mammoth extinction.

8. Climate change and human activity interacted to exacerbate the extinction.

The extinction of woolly mammoths occurred around 4,000 years ago, primarily due to climate change, not human activity, according to a study published in Nature.

Climate change led to vegetation changes, affecting mammoth populations, as researchers found that climate change, in particular rainfall, directly led to changes in vegetation, which affected mammoths.

Human hunting played a role in their extinction, but climate change was the main cause, with the extinction of mammoths being influenced by the speed of climate change, as they could not adapt quickly enough to the radical changes in the landscape and food scarcity.

The warming of the climate itself, with the speed of climate changes playing a crucial role, contributed to the extinction of mammoths, as researchers concluded that climate change led to the extinction of mammoths, not human activity.

The extinction of woolly mammoths was influenced by the interaction between climate change and human activity, as humans hunted mammoths for meat, using their bones for dwellings and tusks for harpoons and musical instruments.

The extinction of woolly mammoths was influenced by the warming of the climate itself, with the speed of climate changes playing a crucial role, as researchers found that the cause of the extinction of mammoths in Siberia was primarily a sharp climate change, not human activity.

An international team of researchers found that the cause of the extinction of mammoths in Siberia was primarily a sharp climate change, not human activity.
The article is published in the journal Nature.
Woolly mammoths became extinct only about four thousand years ago.
They were not only the main source of meat of ancient people – the latter made from their bones the basis for dwellings, from their tusks made harpoons and even musical instruments.
Therefore, there is a widespread theory that the main cause of extinction was humans.
Researchers from the Institute of Earth Sciences of St. Petersburg State University together with colleagues from the UK, Denmark, China, Norway and the United States decided to restore the appearance of the tundrosteppe, which was inhabited by mammoths.
To do this, they using the shotgun method — obtaining from a random massive sample of cloned fragments of the original sequence — analyzed the DNA of ancient plants and animals collected from 535 different places in the Arctic, where the mammoth lived, over 20 years.
They also analyzed the DNA of more than 1,500 modern plants and animals.
Researchers were able to map the distribution of populations of mammoths and other representatives of the megafauna of the tundrosteppe.
They saw that over time their populations and genetic diversity became smaller and smaller — making survival increasingly difficult.
With the end of the Pleistocene about 12 thousand years ago and the accompanying retreat of glaciers and the formation of rivers, lakes and marshes, vegetation has decreased in volume, and it has become insufficient to maintain the previous level of populations.
As the climate warms, trees and swamp plants have taken the place of former mammoth pastures.
“We have shown that climate change, in particular rainfall, has directly led to changes in vegetation.
According to our models, people did not have any influence on them [mammoths], ” said the first author of the work, a researcher at the University of Cambridge Yuchen Wang.
However, the extinction of mammoths was influenced not only by the warming of the climate itself.
“His speed was the last nail in the lid of the coffin – they (megafauna tundrosteppe – approx.
“Tape.ru ”) could not adapt quickly enough, when the landscape radically changed and food was not enough, ” said the head of the scientific group, Professor of Copenhagen and Cambridge universities Eske Willerslev.

Scientists have told what the Earth would be without Homo sapiens
The researchers say that in general, the planet could be an exciting place, which would be inhabited by representatives of megafauna.
Scientists believe that without humans, the Earth would be a more wild and fertile place, in which giants such as ostrich moa birds with a height of 3.6 meters still lived.
They lived in New Zealand for millions of years, but disappeared 750 years after their land was invaded by man, writes LiveScience.
The vanished giant moas and eagles of Haast, whose wingspan was 2.6 meters or more, are a small example of how human activity has changed the planet.
The survival of such large animals is crucial in thinking about what the Earth would be like without humans, as such giants have a crucial influence on landscapes.
Senior lecturer in zoology at the University of Gothenburg in Sweden, Seren Forby, says humans have played a crucial role in the extinction of many large mammals.
Forby led the study, published in the journal Diversity and Distributions.
It said that without humans, the Earth would resemble an ecoregion in East Africa, the Serengeti, teeming with life.
In such a scenario, extinct animals, along with elephants, rhinos and lions, would live throughout Europe.
For example, the African lions (Panthera leo) would still be replaced by cave lions (Panthera spelaea), a larger species that lived in Europe about 12,000 years ago.
At the same time, America would be home to larger relatives of elephants and bears, as well as unique species such as the glyptodon – car-sized armadillos and giant sloths.
“In a world without humans, there would be a lot more different species of large mammals, as well as a much more open habitat, ” says Forby.
Elephants or other species of large animals do not tolerate obstacles in their search for food.
In such cases, the territory acquires a less wooded appearance.
The world would be brighter
During the last Pleistocene Ice Age (2.6 million to 11,700 years ago), the Earth was rich in megafauna.
Much of it went extinct after the end of this ice age or millennia later.
A 2021 study from the journal Nature found that climate change had wiped out woolly mammoths as well as other Arctic megafauna, but humans also put additional pressure on these species by hunting them.
Christopher Doughty, an ecologist at the University of Northern Arizona, modeled how large animals, among other things, affected ecosystems by moving seeds and nutrients during eating and defecating.
The expert found that the movement of elements such as phosphorus, calcium and magnesium, which play a crucial role in life, decreased by almost 90% along with the disappearance of megafauna.
The researcher emphasizes that without human intervention, all the necessary elements would be evenly distributed throughout the landscape.
Thus, the soil would be more fertile and productive.
Agriculture and zoning make land less fertile compared to systems in the wild.
Such increased fertility means that the Earth would be much richer in crops and colors, the planet would definitely be brighter without humans.
Without humans, the climate would be different.
Human induced global warming is known to have raised the average temperature by 1 degree Celsius since the early 20th century.
Consequently, the weather on the planet would be cooler without humanity.
A 2016 study in the journal Nature found that current warming delayed the onset of the ice age by at least 100,000 years.
But this should not have happened for another 50,000 years, so it is unlikely that without humans there would be another ice age on Earth right now.
People are inevitable
Modern humans (Homo sapiens) were not always the only hominins on the planet.
The disappearance of Homo sapiens could open up new perspectives for Neanderthals.
There is no single answer to the question of why the Neanderthals died out about 40 thousand years ago.
There were probably several reasons for their disappearance, and Homo sapiens are the main suspects.
Professor Chris Stringer from the Natural History Museum in London believes that the competition between Neanderthals and humans was one of the reasons for the disappearance of the former.
“If Homo sapiens hadn ’ t come to Europe about 45,000 or 50,000 years ago, I think Neanderthals and their descendants would still have lived on Earth, ” Stringer says.
The expert notes that Neanderthals led a complex life in Europe, they faced climate change, were a small group with low genetic diversity.
“Neanderthals probably were already in distress when modern humans came to their lands, and this factor could be the last, ” the expert notes.
But humans could have influenced the survival of more than just Neanderthals.
At least there is another relative of Homo sapiens who shared land with humans and Neanderthals: the Denisovans.
This line is closer to Neanderthals than to modern humans in terms of genes and appearance.
Judging by a number of studies, people interbred with Denisovans, because modern people continue to find the DNA of Denisovans.
It is assumed that Denisovans had a wider range of habitat than Neanderthals.
They may also have more genetic diversity than Neanderthals.
"Perhaps the Denisovans were even better species for survival than the Neanderthals," Stringer said.
In general, Denisovans and Neanderthals could pave the way similar to H. sapiens, moving from hunting and gathering to the development of agriculture.
"There is no obvious reason why Neanderthals or Denisovans would not have evolved if they had the time to do so," he said.

The human footprint can be seen across the planet today, from the towering skyscrapers that define our modern capitals to the pyramids and other ancient relics from our past.
Human activity also represents the sprawling open fields of agriculture, the roads that connect everything together.
But what would the world look like if humans didn ’ t exist before?
Some scientists paint a picture of a pure wilderness and an abundance of species, from fashionable to uncommon.
Trevor Worthy, a paleontologist and assistant professor at Flinders University in Australia, told Live Science: “I think it would be a much more vegetative place with a wealth of animals, of great size, spread across all continents except Antarctica. ”
A world without modern humans may also mean that our extinct human relatives, such as Neanderthals, will still exist.
And, of course, they would have changed the scene as well.
Humans shaped the world at the expense of many species, from the dodo (Raphus cucullatus) to the Tasmanian tiger (Thylacinus cynocephalus), which pushed us to extinction through activities such as hunting and habitat destruction.
The rate of extinction on Earth today is more than 100 times what it would have been without humans, according to the most conservative estimates, and has not been higher since the Cretaceous and Paleogene (K-Pg) extinction event that wiped out about 80% of animal species, including non-floating dinosaurs, 66 million years ago.
In other words, humans collided with the planet like an asteroid, and the dust continues to settle as wildlife continues to deteriorate.
“My great-grandfather was able to see herds of thousands of parrots in the landscape, my grandfather saw a hundred flocks, my father saw little and I ’ m lucky if I could see two in the woods, ” said Worthy.
The human-driven decline of nature suggests that Earth would be a more wild place without us, with some lost giants, such as moas, standing out the most.
This group of ostrich-like birds, some of which extend up to 11.8 feet (3.6 m) in New Zealand, evolved over millions of years.
Within 200 years of humans reaching their land 750 years ago, all nine species of moa have disappeared, along with at least 25 other vertebrate species, including the giant Haast eagles (Hieraaetus moorei) that hunted moa, according to Worthy.
The giant moa and the Haast vultures are recent examples of large animals whose eventual extinction is linked to human activities, such as unsustainable hunting and the introduction of invasive species into new habitats.
They are also indicators of what our relationship with large animals might be like elsewhere.
The survival of large animals is crucial to speculate on the existence of a land without humans, as these monsters have a significant impact on the landscape.
– Serengeti System
Soren Furby, senior lecturer in zoology at the University of Gothenburg in Sweden, believes that humans played a key role in the disappearance of many large mammals thousands of years ago.
He led a 2015 study, published in the journal Diversity and Distributions, which suggested that without humans, the Earth would be much like the contemporary Serengeti system, an African ecosystem teeming with life.
In this scenario, extinct animals similar to those found in Serengeti today – including elephants, rhinos and lions – would live across Europe.
For example, instead of African lions (Panthera leo), there are still cave lions (Panthera spelaea), a slightly larger species that lived in Europe until about 12,000 years ago.
Meanwhile, the Americas will be home to relatives of huge elephants and bears, along with unique species, according to Forby.
"In a world without humans, there will be much more diversity than large mammals, and if you see a greater diversity than large mammals, you tend to see a more open habitat," Forby said.
Elephants and other large animals are well identified when finding food, and will not tolerate unnecessary obstacles.
“If you ’ re old enough, it might be easier to knock on a tree and eat fresh leaves on top of it, ” Forby said.
But also, if there are a large number of large mammals, there is a tendency to have fewer wooded plants in the first place, he said.
Large animals, such as elephants, are known as megafauna.
During the last ice age (2.6 million to 11,700 years ago), the world was rich in megafauna, but most of them died at the end of the ice age, or in the thousands of years since.
For example, about 38 genera of large animals went extinct in North America at the end of the last ice age, according to a 2020 study published in the journal Proceedings of the National Academy of Sciences.
Over the past century, scientists have debated whether natural climate changes or human activities, such as overfishing, are the main reason for the decline of these large animals.
A 2021 study published in Nature concluded that climate change ultimately wiped out the woolly mammoths (Mammuthus primigenius) and other Arctic megafauna that survived the end of the ice age.
However, humans hunted mammoths.
Scientists who believe humans may have been the main factor in their extinction, such as Forby, argue that mammoths survived climate change before humans appeared and would probably survive to this day had it not been for the added pressure humans placed on them.
Christopher Dottie, an associate professor and ecologist at Northern Arizona University, is modeling how past and present large animals transport seeds and nutrients through eating and defecating.
His work indicates that the transport of elements such as phosphorus, calcium and magnesium, which are important for life, was reduced by more than 90% through the extinction of large animals.
Dotti hypothesizes that without humans, elements would be evenly distributed across the landscape.
This means more fertile soil, which makes ecosystems more productive.
Humans tend to group elements together through practices such as farming and creating fenced areas, so that these areas become less fertile over time compared to terrestrial systems, according to Dauty.
Greater fertility means that plants can devote their resources to more fruit and flowers, so that the world looks more vibrant and feeds more animals.
While it is difficult to determine how humans and megafauna have influenced climate change for thousands of years with evidence obscured over time, it is much easier to judge our impact on Earth ’ s climate today.
Through global warming, caused by activities such as burning fossil fuels, humans have raised the global average temperature by about 1.8 degrees Fahrenheit (1 degrees Celsius) since the beginning of the 20th century.
Therefore, the Earth would have been at least colder without us.
A 2016 study published in the journal Nature concluded that human-induced warming would delay the next ice age by at least 100,000 years.
And it wasn't due for another 50,000 years, though, even without human delay, so it's unlikely that Earth would be in the middle of another ice age today if we didn't exist.
Humans are inevitable.
Scientists aren ’ t sure why Neanderthals went extinct about 40,000 years ago, but because they mate with Homo sapiens, parts of their DNA are found in some of us.
There were probably multiple causes of Neanderthal death, but we're a prime suspect.
Chris Stringer, a professor and research leader in human origins at the Natural History Museum in London, believes competition for resources was a factor in the disappearance of Neanderthals.
“If we weren ’ t around, if we hadn ’ t come to Europe 45,000 or 50,000 years ago, I think they ’ d probably stay here, ” he told Live Science.
According to Stringer, Neanderthals lived a complex life in Europe, similar to modern humans, but they had difficulty adapting to climate change and were relatively few in number, with low genetic diversity.
This is bad news for any species, as it is a sign of inbreeding and ill health.
Stringer said Neanderthals were probably “already in trouble, and when modern humans got there too, I think that ’ s probably what pushed them to the edge. ”
Scientists are still learning about at least one human lineage that lived around the same time as modern humans and Neanderthals: Denisovans.
This lineage appears to be closer to Neanderthals than modern humans in genes and appearance, but it can be distinguished from Neanderthals with very large molars.
There is evidence of DNA in current humans living in places like New Guinea in Oceania — a finding that suggests Denisovans were in Southeast Asia interacting with ancestors of modern humans who later settled in the East, according to a 2012 study published in the journal Science.
These Denisovan interactions, along with fossil evidence, suggest that they had a larger geographic range than Neanderthals, encompassing a variety of environments and, therefore, arguably, were more adaptive than Neanderthals.
DNA evidence also suggests that Denisovans may have had greater genetic diversity than Neanderthals, according to Stringer.
Stringer said: “There ’ s no reason why Neanderthals or Denisovans shouldn ’ t do it eventually, given enough time. ”
He added that they may have overcome any potential intellectual deficiency, which is not clear to them, through evolution.
So maybe the world won ’ t look completely different after all.
Likewise, they could have made the same mistakes we have made since then.
So, global warming could have been here, but with Neanderthals or Denisovans leading it, not us.

An international team of researchers found that the cause of the extinction of mammoths in Siberia was primarily a sharp climate change, not human activity.
The article is published in the journal Nature.
Woolly mammoths became extinct only about four thousand years ago.
They were not only the main source of meat of ancient people – the latter made from their bones the basis for dwellings, from their tusks made harpoons and even musical instruments.
Therefore, there is a widespread theory that the main cause of extinction was humans.
Researchers from the Institute of Earth Sciences of St. Petersburg State University together with colleagues from the UK, Denmark, China, Norway and the United States decided to restore the appearance of the tundrosteppe, which was inhabited by mammoths.
To do this, they using the shotgun method — obtaining from a random massive sample of cloned fragments of the original sequence — analyzed the DNA of ancient plants and animals collected from 535 different places in the Arctic, where the mammoth lived, over 20 years.
They also analyzed the DNA of more than 1,500 modern plants and animals.
Researchers were able to map the distribution of populations of mammoths and other representatives of the megafauna of the tundrosteppe.
They saw that over time their populations and genetic diversity became smaller and smaller — making survival increasingly difficult.
With the end of the Pleistocene about 12 thousand years ago and the accompanying retreat of glaciers and the formation of rivers, lakes and marshes, vegetation has decreased in volume, and it has become insufficient to maintain the previous level of populations.
As the climate warms, trees and swamp plants have taken the place of former mammoth pastures.
“We have shown that climate change, in particular rainfall, has directly led to changes in vegetation.
According to our models, people did not have any influence on them [mammoths], ” said the first author of the work, a researcher at the University of Cambridge Yuchen Wang.
However, the extinction of mammoths was influenced not only by the warming of the climate itself.
“His speed was the last nail in the lid of the coffin – they (megafauna tundrosteppe – approx.
“Tape.ru ”) could not adapt quickly enough, when the landscape radically changed and food was not enough, ” said the head of the scientific group, Professor of Copenhagen and Cambridge universities Eske Willerslev.

Scientists have told what the Earth would be without Homo sapiens
The researchers say that in general, the planet could be an exciting place, which would be inhabited by representatives of megafauna.
Scientists believe that without humans, the Earth would be a more wild and fertile place, in which giants such as ostrich moa birds with a height of 3.6 meters still lived.
They lived in New Zealand for millions of years, but disappeared 750 years after their land was invaded by man, writes LiveScience.
The vanished giant moas and eagles of Haast, whose wingspan was 2.6 meters or more, are a small example of how human activity has changed the planet.
The survival of such large animals is crucial in thinking about what the Earth would be like without humans, as such giants have a crucial influence on landscapes.
Senior lecturer in zoology at the University of Gothenburg in Sweden, Seren Forby, says humans have played a crucial role in the extinction of many large mammals.
Forby led the study, published in the journal Diversity and Distributions.
It said that without humans, the Earth would resemble an ecoregion in East Africa, the Serengeti, teeming with life.
In such a scenario, extinct animals, along with elephants, rhinos and lions, would live throughout Europe.
For example, the African lions (Panthera leo) would still be replaced by cave lions (Panthera spelaea), a larger species that lived in Europe about 12,000 years ago.
At the same time, America would be home to larger relatives of elephants and bears, as well as unique species such as the glyptodon – car-sized armadillos and giant sloths.
“In a world without humans, there would be a lot more different species of large mammals, as well as a much more open habitat, ” says Forby.
Elephants or other species of large animals do not tolerate obstacles in their search for food.
In such cases, the territory acquires a less wooded appearance.
The world would be brighter
During the last Pleistocene Ice Age (2.6 million to 11,700 years ago), the Earth was rich in megafauna.
Much of it went extinct after the end of this ice age or millennia later.
A 2021 study from the journal Nature found that climate change had wiped out woolly mammoths as well as other Arctic megafauna, but humans also put additional pressure on these species by hunting them.
Christopher Doughty, an ecologist at the University of Northern Arizona, modeled how large animals, among other things, affected ecosystems by moving seeds and nutrients during eating and defecating.
The expert found that the movement of elements such as phosphorus, calcium and magnesium, which play a crucial role in life, decreased by almost 90% along with the disappearance of megafauna.
The researcher emphasizes that without human intervention, all the necessary elements would be evenly distributed throughout the landscape.
Thus, the soil would be more fertile and productive.
Agriculture and zoning make land less fertile compared to systems in the wild.
Such increased fertility means that the Earth would be much richer in crops and colors, the planet would definitely be brighter without humans.
Without humans, the climate would be different.
Human induced global warming is known to have raised the average temperature by 1 degree Celsius since the early 20th century.
Consequently, the weather on the planet would be cooler without humanity.
A 2016 study in the journal Nature found that current warming delayed the onset of the ice age by at least 100,000 years.

This lineage appears to be closer to Neanderthals than modern humans in genes and appearance, but it can be distinguished from Neanderthals with very large molars.
There is evidence of DNA in current humans living in places like New Guinea in Oceania — a finding that suggests Denisovans were in Southeast Asia interacting with ancestors of modern humans who later settled in the East, according to a 2012 study published in the journal Science.
These Denisovan interactions, along with fossil evidence, suggest that they had a larger geographic range than Neanderthals, encompassing a variety of environments and, therefore, arguably, were more adaptive than Neanderthals.
DNA evidence also suggests that Denisovans may have had greater genetic diversity than Neanderthals, according to Stringer.
Stringer said: “There ’ s no reason why Neanderthals or Denisovans shouldn ’ t do it eventually, given enough time. ”
He added that they may have overcome any potential intellectual deficiency, which is not clear to them, through evolution.
So maybe the world won ’ t look completely different after all.
Likewise, they could have made the same mistakes we have made since then.
So, global warming could have been here, but with Neanderthals or Denisovans leading it, not us.

Okay, let me start by understanding the user's request. They want a concise report on Greenland’s rare earth minerals, focusing on value, location, extraction difficulty, and interested parties. The original report is 740 words and needs to be under 400. I need to shorten it without adding new info, keep all original facts, and maintain citations.

First, I'll go through each paragraph of the original report and identify redundant points. For example, the Tanbreez Mining license is mentioned multiple times, so I can combine those into one sentence. Also, environmental concerns are repeated, so I should consolidate those.

I need to ensure each claim is cited correctly with the exact document IDs. Let me check each sentence to make sure the citations are accurate. The user emphasized not adding new sentences, so I must stick strictly to the original content.

The user's context is about investment, so the report should highlight economic value, location, extraction challenges, and interested parties. I'll structure the revised report to focus on these aspects. For instance, the estimated value and location of deposits should be clearly stated. Mentioning the EU Framework Programme and Copernicus Satellite Programme shows international support, which is important for the investor's due diligence.

I need to make sure each sentence is on a separate line and the report is under 400 words. Let me count the words after revisions. The original has 700 words, so cutting down to 400 requires removing about 300 words. I'll eliminate redundant sentences and merge similar points without losing essential information.

I should also check for technical terms or specific data points that are important for the investor's decision. For example, the mention of the EU Framework Programme and Copernicus Satellite Programme are key for international support and exploration. Including these shows the external interest and support, which is vital for the investor's due diligence.

Finally, I'l
