Pasteur invented a cleansing method known as Pasteurization. Using pasteurization, liquids, such as milk, are heated in order to kill off any living bacteria in the substance. Once the bacteria have been killed, the liquid is returned to normal temperature and is safe to drink without fear of getting infected. Pasteurization saved peoples' lives because it prevented countless people from becoming sick after drinking certain liquids (especially milk, which is still pasteurized currently).
