From the mid-20th century, plastics are widely used. On the one
hand, the plastic material is an important element of modern
life, on the other hand has become a serious environmental
pollution problems, research has been done in the scientific
community. From the distribution status of the land and the sea
view, plastic has become a human world of geology key indicator,
it is a unique formation constituents.
A study by the University of Leicester in England, due to the impact of human activities, to the middle of this century, the Earth's marine and terrestrial sediments will be a lot of plastic garbage.The results of the study published in the "Anthropocene" (Anthropocene) journals. Earlier scientists, because humans have on the planet a very extensive and unprecedented change, the geology, the Earth has entered a new era - Anthropocene.
The study of human evidence has entered the human world were seeing, and being persistent because mass production of artificial plastic rather significant change, we have also entered the "Plastic Age" made the earth's surface.Paleontologists Department of Geology, University of Leicester Jan Zalasiewicz explained:.. "In our grandparents were kids, they know nothing about but now almost plastic, plastic has become our lives an indispensable part of them everywhere They are used to package food, water and milk as a container, providing full bloom eggs, yogurt and chocolate boxes, as well as pharmaceutical aseptic saved. most of the clothes we wear is made of plastic. "
"Plastic can be said that everywhere on Earth, from the top of the mountains to the deep seabed, and these plastics can become fossils saved to far into the future. We are now able to produce every three years nearly one billion tons of plastic. If the past few decades All are made in plastic food film, enough to cover the entire planet. according to the current production trends, by mid-century, the total amount of plastic produced by human food if converted into a film that can cover several layers of the Earth. "
The study also showed that the Earth's geology plastics will produce long-lasting effects, because they state very stable, very difficult to degrade. Thus, when the plastic garbage scattered on the land, it will become part of the soil, and eventually rushed to the sea. Plankton, fish box recycling, seabirds and other marine animals are likely to die from eating plastic waste. Plastic garbage can drift thousands of kilometers in the sea, many of them will gather in "Ocean Garbage Patch", or eventually washed up on a remote beach in the sea. Plastics may also sink to the bottom and become part of the future formation.From the mid-20th century, plastics are widely used. On the one hand, the plastic material is an important element of modern life, on the other hand has polystyrene recycling become a serious environmental pollution problems, research has been done in the scientific community.
From the distribution status of the land and the sea view, plastic has become a human world of geology key indicator, it is a unique formation constituents."The next millennium, as the temporary storage methods - landfill, etc. - the gradual erosion of the sediment into the plastic will continue to cycle through, we can already distinguish between different types of plastic development, as well as processed products. - known as the 'science and technology fossils' to fine time division of the human world will be buried in sediment formation inside the plastic, and many also have the potential for long-term preservation, "Zalasiewicz professor adds," Once buried up, because durable stability, there is a large plastic may become fossils, millions of years later became evidence indicates some sort of super-friendly materials. plastics age may continue for quite a long time. "Dr. Matt Edgeworth involved in the study, said: "Regarded as the plastic material anthropology and geology studies seem strange, because they are so new, but we found that the recent formation of more and more plastic envelopes, plastic can be used as. very good stratigraphic markers. "
In 2016, led by Professor Jan Zalasiewicz "Anthropocene Working Group" will gather more evidence about the human world, to help facilitate the formal establishment of this new era of units, and its definition and interpretation. Study co-author Colin Waters added: "We have been accustomed to living among plastic waste, but it is some 'invisible' plastic particles - from cosmetics and toothpaste, as well as our clothing fibers - the bottom of lakes and in the ocean increasing accumulation, perhaps this will be the geological record is very important legacy.
