Final answer:
Bog bodies are found by people during various activities such as removing machinery, hunting for bog butter, or digging up peat, with the most common being the latter. The unique preservation is due to the low oxygen, high acidity, and low temperatures in bogs, which inhibit decomposition. The correct answer to how people find bog bodies is D) All of the above.
Step-by-step explanation:
People find bog bodies through various methods. These preserved humans and animals are often stumbled upon by people performing routine activities in bogs. The correct answer to how people find bog bodies is D) All of the above. The bodies can be found while removing machinery from bogs, searching for bog butter (an ancient method of preserving butter in peat bogs), or most commonly while digging up peat for use as a fuel source or soil additive in gardening. The unique conditions of bogs contribute to the preservation of bodies. Bogs have a low oxygen content and are rich in organic acids, which lower the pH level, slowing down the process of decomposition significantly. These factors create an environment in which microbial activity is suppressed, preventing the bodies from decaying as they would under normal circumstances.
