List and describe as many changes in human behaviors as you can think of that contributes to a decreased exposure to microbes.

antibiotics- decrease exposure by killing or impacting growth of microbes

cleaners/antimicrobial products/hand-washing/hand sanitizers- eliminates exposure to microbes, usually for the better because they kill pathogenic microbes, but also kill microbes that could be beneficial

covid precautions(masks, social distancing, quarantine)- an increase in covid pre-cautions from covid has definitely decreased exposure to microbes by limiting exposure to others and their microbes
