The connection between Laws of Manu and Bubonic Plague

To start off, the Manu society, located in Ancient India, carried the belief that they had to sustain their environment through government and religious leaders. Thus, they created the Laws of Manu, in order to set up a relationship between the humans and the environment. How this law code was related to our present laws was that it pertained to Christians, Jews, and Muslims. A question we can ask is " What laws of modern society are comparable to Laws of Manu? What are actions that we take to conflict these laws?" Made in 200 CE, some of the rules that they had created had been non-violence. In other words, this law would extend to humans and every other living thing, such as animal and plants. So they tried to carry on the motive of a Quaker, or a Pacifist, causing no injury. Additionally, they had a strict policy of not eating meat due to their beliefs. They identified this as bringing disease and murder to the planet, so their punishment was to plant trees. Next, they also tried to prevent pollution. This included air pollution, water pollution, and cleaning of food. They were extremely careful with the environment, leaving it as if it were untouched by humans. However, many of the things present society does that doesn't follow Manu perspective is that we don't follow these laws that were set upon us, for example, we only resolve most of our problems and way of life through violence and the death of numerous people in this world. Not to mention the fact that littering happens daily, making our society and environment dirty and foul. Switching from this society, something that had a great impact on Europe had been disease. It could kill people and destroy an entire society. It's basically a bad relationship between the environment and humans. Beginning in China and the Mediterranean region, plagues began to spread throughout most trading routes and as the carriers traveled to different nations, it became a pattern where they gave off the disease to other merchants, in turn would take it back to their community, spreading it to the rest of the people, and then to others. This spreading brought much death to Europe. This plague was known as the Bubonic Plague. This was from bacteria in fleas, which was found in rats. Since society wasn't clean, rats managed to reproduce and spread more disease by eating garbage and soon moving aboard trading ships. Many died and grabbed the disease airborne, or just by sneezing and coughing. This would only give them a week to live. But what made matters worse was that to try to escape this, civilians traveled to different towns, not knowing that they carried the disease, and in turn spreaded it until societies died off. A question that can be asked by this is " To what extent might the Laws of Manu might have prevented the spread of plagues?" The answer can be as determined as their society was, they would have decided to continue their good relationship with the environment, to have clean food/ cooking it the right method,  engaging a cleaner hygiene, and having a source where there is clean water. Lastly, a question that would connect to us is " How did people respond to Bubonic Plague which made things much worse? To what extent have we improved human response?" The way people in Europe made the conflict worse was by spreading the sickness as they moved, which brought more death, and additionally, they had an unsafe water source which was wells. Humans have improved since they have a purification system and a cleaner hygiene. Also, while traveling, we have rules and regulations, in order to prevent disease to spread. Lastly, due to technology, we have many medications that would treat illness.
