Today, there are very few bogs that exist in northern Europe due to excessive cutting. Attempts have been made to regrow bogs in Germany, but the process is very slow (a raised bog may grow a millimeter in only one year). (Deem, 1988-2003).
THE BODIES OF "THE BOG PEOPLE".
.
"The Bog People" are among the most perfectly preserved bodies in the world, due to the special chemical properties of the peat bog. In peaty conditions, the preservation of the flesh and blood sometimes occurs while the bones of such bodies usually become spongy or decompose. The peat has acids that have preserved these bodies down the last detail (such as hair and nails). It is unknown how many bog bodies have been found - many have been lost or reburied since their discovery. (http://tornadohills.com/strange/bog_people.htm). Given the modern scientific techniques and technology in the world today, scientists and archaeologists can gather important information about the lives and deaths of these people and how they looked during their life, through facial reconstructions and remains of hair and clothing. .
SCIENTIFIC TECHNIQUES.
A very important tool in archaeology is Radiocarbon dating (also known as Carbon 14 or C14), which determines how much radioactive carbon is present in the remains of what was once a living organism. People and animals regularly take radioactive carbon into their lives by eating meat and plants. The radioactive carbon is no longer refilled after an organism dies. The radioactive carbon activity increasingly declines, it can no longer be detected after 70, 000 years. The radiation's strength can therefore be used to determine the age of an organism. Using this method, scientists can determine the age of various types of materials such as charcoal, peat, or shells. Bog bodies have been dated using this method. (http://www.bogpeople.org/bog_uk/index.html). Another spectacular technique used in bog body research is the reconstruction of facial features.
