Jessica Green: Are we filtering the wrong microbes?

The video discusses the prevalence of microorganisms indoors and their impact on health. It highlights a study comparing mechanical and natural ventilation in hospitals, revealing that mechanical ventilation reduces microbial diversity but increases potential pathogens. The findings suggest reconsidering current building practices to promote healthier indoor environments by managing microbial ecosystems, similar to how national parks are managed.

What percentage of their lives do people typically spend indoors?

• 70%

• 50%

• 100%

• 90%

How do microbes primarily enter buildings?

• Through electrical outlets

• Through windows and ventilation systems

• Through water pipes

• Through food

What was a key finding about microbial diversity in mechanically ventilated rooms?

• It had no diversity

• It was less diverse than outdoor air

• It was more diverse than outdoor air

• It was identical to outdoor air

What is a potential health risk associated with mechanically ventilated air?

• Higher humidity

• Decreased carbon dioxide levels

• Increased oxygen levels

• Higher probability of encountering pathogens

What type of microbes are commonly found in outdoor air?

• Microbes from animal fur

• Microbes from human skin

• Microbes from food

• Microbes from plant leaves and dirt

Why is it important to reconsider current building practices?

• To promote healthier indoor microbial communities

• To reduce construction costs

• To improve energy efficiency

• To increase building size

What analogy is used to describe managing indoor microbial communities?

• Managing a national park

• Managing a factory

• Managing a zoo

• Managing a library
