Answer 1

Explanation:

Pollution is not a new phenomenon. In fact, pollution has been a problem since the appearance of our earliest ancestors. Increasing human populations have opened the door to more bacteria and disease. During the Middle Ages, diseases such as cholera and typhoid fever broke out all across Europe. These epidemics were directly related to unsanitary conditions caused by human and animal wastes, and garbage. In 1347, the bacterium Yersinia pestis, carried by rats and spread by fleas, caused the "Black Death" — an outbreak of bubonic plague. Unsanitary conditions provided the perfect environment for the deadly bacteria to flourish
