Bacteria and Viruses Are Raining Down on Us All the Time

The video explores the presence and movement of airborne microbes, including viruses and bacteria, which can travel vast distances and potentially spread diseases. While most are harmless, some can cause health issues, and their movement is influenced by wind patterns and human activities. Climate change may exacerbate these issues by increasing the amount of dust and microbes in the atmosphere.

What is the primary reason we inhale thousands of microbes per hour?

• Microbes are produced by plants.

• Microbes are released from soil and water surfaces.

• Microbes are created by industrial pollution.

• Microbes are generated by human activities.

How can microbes travel across continents?

• By attaching to migrating birds.

• By hitching a ride on dust particles in the atmosphere.

• Through ocean currents.

• Via human transportation systems.

Why might coral reefs be affected by global dust transport?

• Dust increases water temperature.

• Dust carries pathogens that can harm coral reefs.

• Dust blocks sunlight needed for photosynthesis.

• Dust provides nutrients that promote algae growth.

What was a significant finding related to Kawasaki disease?

• It is caused by a known virus.

• It is linked to wind patterns from Asia.

• It is spread through contaminated water.

• It is transmitted by insects.

What is a potential consequence of climate change on microbial movement?

• Decrease in microbial diversity.

• Increase in microbial movement due to more dust and intense weather.

• Stabilization of microbial populations.

• Reduction in disease outbreaks.
