The environmental impact of the Maya civilization is still visible today

(Read the article on one page)

A new study has found that the Maya civilization of Central America had a considerable impact on the surrounding environment, the effects of which are still visible. Activity from 2,000 years ago contributed to the decline and continues to influence us today.

Many Maya structures can still be seen to this day including the Temple of Kukulkan in the city of Chichen Itza in the southern Mexican state of Yucatan. Kukulkan was the feathered serpent, the Maya snake deity. Maya civilization was also known for the development of the Maya script, the only Mesoamerican writing system to be deciphered thus far.

Researchers from the University of Texas constructed the study from a synthesis of old and new data. They believe that the ‘Mayacene’ could be interpreted as a microcosm of today’s ‘Anthropocene’, in that it was a period when human activity began to significantly affect the environment. The team analyzed the behaviour of the Maya and its impacts on climate, vegetation, hydrology and lithosphere – the rock and soil – from 3,000 to 1,000 years ago. They found that the Maya infrastructure impacted the ecosystems in the surrounding forest. These impacts can be identified through six markers, known as ‘golden spikes’, which indicate large-scale change. These include rocks of “Maya Clay”, unique soil sequences, carbon isotope ratios, widespread chemical enrichment, building remains and landscape modifications. There are also signs of Maya-induced climate change.

“These spikes give us insight into how and why Mayas interacted with their environment, as well as the scope of their activity” said Sheryl Luzzadder-Beach, co-author and chair of the Department of Geography and the Environment. “In studying the wetland systems, we were surprised to find a combination of human and natural contributions. Geochemical changes indicated that some wetlands were natural, while others were built landscapes used to grow crops away from the large population.”

Beach added that historically it’s common for people to talk about bad things that happened with past environmental change, such as erosion and climate change caused by deforestation. However, the way in which the Maya altered their environment in order to create vast field systems, as a response to rising sea levels, can teach us a lot. Some studies suggest that deforestation and other land-use changes contributed to warming and drying of the regional climate during the Classic Period, 1,700 to 1,100 years ago. Many of today’s forests are still affected by these activities and many of the features from that period, such as structures, terraces and wetlands, remain in existence to this day.

The Maya Clay and soil sequences provide an indication of soil erosion, land-use changes and periods of instability. In particular, soil profiles near wetlands reveal enlarged carbon isotope ratios resulting from agriculture and corn production. The researchers also noted a three to four-fold increase in phosphorus throughout the sediments dating from the Maya period. However, the most visual impact is in the form of building material remains and landscape modification. The researchers believe this indicates Maya water management processes used by the civilization to adapt to a period of climate change.

Lead researcher on the study, Professor of Geography and the Environment Tim Beach, said that most popular sources discuss the Anthropocene, involving human impacts on the climate since the Industrial Revolution. However, we are actually looking at a deeper history when we consider human impact on the planet.

“Though it has no doubt accelerated in the last century, humans' impact on the environment has been going on a lot longer” said Professor Beach, speaking to The Daily Mail .

The team will publish the study shortly, entitled “Ancient Maya impacts on the Earth's surface: An Early Anthropocene analog?” in the journal Quaternary Science Reviews.

Well I guess this shoots the crying Native American on the side of the highway TV ad all to hell. I thought the Native cultures of thousands of years ago whose land was stolen by the evil polluting devil white man were one with the land and sea. The pedestal that these cultures are put on have always been a lie. They were violent, war making, human sacrificing and apparently land raping humans. They had no morals and it's no wonder their 'civilization' died out. It's almost always the case some idiot gets put in charge - whether an Emperor, King or POTUS - they screw up the society so bad it starts a downhill slide and collapses.

Can someone please explain the value of this research to me, in reply.

Because, to me, this seems like a massive waste of time, resources and human potential. How does this study advance the human experience and make life better for humans alive today? - in this reality.

These 'scientists' from Texas have nothing better to do than draw foregone conclusions from questionable data - for what purpose? Can their data be used in 'predictive modeling' or avoidance strategy?

We know humans have an impact on the environment - we know this and have known nearly forever, the nature and results of those impacts.

Some might argue that "we need to know the details of those impacts, to avoid them today" Too little, too late, and too lame of a reply.

I mean, the rain forest is collapsing for the want of Nutella, oceans are dying, an elephant dies every 15 minutes and tigers are nearly extinct...

...and these big heads are looking to do what?

Why not study the effects of large cities on the environment?...TODAY! Work towards solutions for the biggest problems a study of that type might reveal.

Science as it is today, seems to have lost its way

Scientists today seem to be nothing more than corporate shills and government trolls - lying in Journals and 'studies'; making up facts as they go roaming the world, looking to prove their own value to the rest of us.

IMO, the ego and ignorance that many scientists live in today, defeats any attempt to expunge knowledge; useless or otherwise.

what a waste

There are plenty of studies on the impact of modern cities on the environment. Perhaps you have heard of Climate Change or Global Warming? The article even makes reference to such studies when it mentions the Anthropocene Epoch. This website has a particular focus on history and so it is going to report on studies about history. If you are looking for studies on the impact of contemporary society on the environment and proposed solutions, you are one click away from finding it if you actually look.

Beginning around 90,000 years ago, during an interglacial period, Anatomically Modern Humans were able to take advantage of the favorable climatic conditions and migrate throughout Africa and into Asia. Soon thereafter, identifiable culture can be found in the archaeological record. As far as can be told, it was Homo Sapiens living in Africa that would make the first symbolic paintings, but Neanderthals soon did this as well.

The ancient and mysterious Sphinx, Giza, Egypt.
In 1995, NBC televised a prime-time documentary hosted by actor Charlton Heston and directed by Bill Cote, called Mystery of the Sphinx. The program centered on the research and writings of John Anthony West, a (non-academic) Egyptologist, who, along with Dr. Robert Schoch, a professor of Geology at Boston University, made an astounding discovery on the Great Sphinx of Giza in Egypt.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
