Plastiglomerate
Plastiglomerate is a rock made of a mixture of sedimentary grains, and other natural debris (e.g. shells, wood) that is held together by plastic. It has been considered a potential marker of the Anthropocene, an informal epoch of the Quaternary proposed by some social scientists, environmentalists, and geologists. Origin Plastiglomerates form along shorelines where natural sedimentary grains and organic debris are agglutinated by melted plastic. They can be created during campfire burning, as has been reported from Kamilo Beach on the island of Hawaii, or during hot weather, as is the case on Trindade Island. Depositional environment Plastiglomerate could potentially form a marker horizon of human pollution on the geologic record. and may survive as future fossils. Plastiglomerate may also conceivably form in plastic-polluted regions affected by lava flows or forest fires. They have been found on the surface as well as beneath the sand. This suggests that plastiglomerates are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fossil Record
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolu ...

Plastics And The Environment
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1,10 ...

Archaeology
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthropology
Anthropology is the scientific study of humanity, concerned with human behavior, human biology, cultures, societies, and linguistics, in both the present and past, including past human species. Social anthropology studies patterns of behavior, while cultural anthropology studies cultural meaning, including norms and values. A portmanteau term sociocultural anthropology is commonly used today. Linguistic anthropology studies how language influences social life. Biological or physical anthropology studies the biological development of humans. Archaeological anthropology, often termed as 'anthropology of the past', studies human activity through investigation of physical evidence. It is considered a branch of anthropology in North America and Asia, while in Europe archaeology is viewed as a discipline in its own right or grouped under other related disciplines, such as history and palaeontology. Etymology The abstract noun ''anthropology'' is first attested in reference t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Pollution
Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. Plastics are inexpensive and durable, making them very adaptable for different uses; as a result, manufacturers choose to use plastic over other materials. However, the chemical structure of most plastics renders them resistant to many natural processes of degradation and as a result they are slow to degrade. Together, these two factors allow large volumes of plastic to enter the environment as mismanaged waste and for it to persist in the ecosystem. Plastic pollution can afflict land, waterways and oceans. It is estimated that 1.1 to 8.8 million tonnes of plastic waste enters the ocean from coastal communities each year. It is estimated that there is a stock of 86 million tons of plastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kamilo Beach
Kamilo Beach (literally, ''the twisting'' or ''swirling currents''Clark, John R. K. (1985), ''Beaches of the Big Island'', University of Hawaii Press, , p. 69 in Hawaiian), is a beach located on the southeast coast of the island of Hawaii. It is known for its accumulation of plastic marine debris from the Great Pacific Garbage Patch. History In ancient times, Kamilo Beach was a location where Native Hawaiians would go to find large evergreen logs that drifted ashore from the Pacific Northwest, which they used for building dugout canoes. It was also a location where those who were lost at sea might eventually wash ashore. Description Kamilo Beach is approximately long, and is located on the remote southeast coast of the Kaū District on the island of Hawaii, at coordinates . There are no paved roads to the beach. This beach, situated on a lower lava terrace, is a storm beach. It was formed by the deposit of large amounts of sand blown by prevailing winds. At the point of ...

Museon
Museon is a museum for science and culture in The Hague, Netherlands. It has collections in the domains of geology, biology, archaeology, history, science and ethnology. __TOC__ Origin The museum was initiated in 1904 by the newspaper director Frits van Paasschen, who wanted to establish a museum where children could learn about industry. Although science and technology became important domains for the museum, the original idea has never been realized. Under the museum's first director, the geologist Herman van Cappelle, the collection policy moved towards natural history and ethnology. Van Paasschen's idea of a museum with a strong education mission however was implemented from the very beginning, expressed by the museum's previous name ‘Museum for Education’. From the start the museum organised lessons for school classes, based on the visual tools that are provided by the museum's collection. Around 1910 the museum was also the first organisation in The Netherlands that pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
