How are microbes helpful to humans?
For example, each human body hosts 10 microorganisms for every human cell, and these microbes contribute to digestion, produce vitamin K, promote development of the immune system, and detoxify harmful chemicals. And, of course, microbes are essential to making many foods we enjoy, such as bread, cheese, and wine.

What will happen if useful microbes are absent in the world?
In the deep oceans, many worms, shellfish, and other animals rely on bacteria for all of their energy. Without microbes, they too would die, and the entire food webs of these dark, abyssal worlds would collapse. Shallower oceans would fare little better. Waste would rapidly build up, for microbes are lord of decay.
Can we survive without bacteria?
“But as long as humans can’t live without carbon, nitrogen, protection from disease and the ability to fully digest their food, they can’t live without bacteria,”— Anne Maczulak, famous microbiologist. But only a few species of bacteria are dangerous.
Can humans survive without gut bacteria?
So essentially, to survive without bacteria, you would need to live in a completely sterile environment in order to prevent near-immediate death from infection, avoid contact with any other life forms, and subsist on a sterilized, liquid diet specially created to be absorbed without gut flora.
What will happen if it never rains?

What do we get from rain?
Rain is droplets of water that fall from clouds. Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air. This vapour rises, cools, and changes into tiny water droplets, which form clouds.
