As snow falls, glacial ice preserves air, water, and biological material. Over time, years and years of biological material become trapped below the ice piled under more recent living things. Much such biological material consists of bacteria and viruses that if unleashed may bring back ancient diseases that have been dormant or bring rise to new diseases that may threaten the human race. These “frozen diseases” can come to the surface over time if the ice continues to melt. For example, most recently a deer that has been frozen in time was brought to the surface. This deer was infected with Anthrax which is a deadly bacteria that once again was met with human contact causing deaths. The rise in temperature due to global warming is the cause.
