According to Andrea Thompson clouds, objects in the sky we see every day; are filled with bacteria, as she states in the article “Earth Clouds Alive With Bacteria”. They say that it is in the water vapor droplets, especially in warmer temperatures. While water droplets and ice crystals make up clouds, they collect dust particles and exhaust from airplanes. Eventually that turns into bacteria that’s lingers in the cloud.

Bacteria and other particles of biological origin are actually pretty good at collecting water vapor to form cloud droplets. Whereas antibiotic particles such as dust are good at collecting water at temperatures below about 14˚F, biological particles seem to be the main active nuclei above that temperature, according to Andrea Thompson, the author of the article.

I really think this is an interesting research topic. I have a few questions about this, does it or can it affect people on earth? How long does the bacteria linger? Lastly, if it affects people how can we get rid of them?
