There is quite a bit on this subject if you do a google search. Moses gave us sanitary laws. What led to the incredible spread of the "black death"? Modern science now knows that unclean streets, poor sanitation, and filth were great contributors. In the l4th century, cities in Europe were filthy, laden with garbage. Refuse was simply thrown in the gutter in London and Paris. For example Moses talks about how important cleanliness is and how people need to wash their hands. In 1850 Ignaz Semmelweis saved lives with three words: wash your hands. He taught people to follow the teachings of Moses in the Bible.

I read a story once about a sword fight and one of the men had his arm cut off. They just threw the arm in an alley because they knew that the rats would carry it off and eat it. This was how they got rid of their garbage back then in violation of the teaching of Moses in the Bible.
