If there were no bacteria, humans and plants wouldn't be able to live. Bacteria help our bodies develop, and they do a process of nitrogen fixation to help plants give us oxygen. Therefore, without bacteria nothing on earth would be able to live.
Everyone would die since we need bacteria inside our body to digest food for us.
Good bacteria (Normal Flora) breaks down nitrogen and without nitrogen, the plants cannot grow, and without plants, no oxygen. Therefore, no bacteria, no life.
But we as humans have bacteria on our body. Not all bacteria is bad. So, if there just wasn't bacteria, then I think it could be bad, because what would happen to the things that need good bacteria to survive? Or even things that need bad bacteria to survive. I don't know if you are familiar with the butterfly effect, but to sum it up quick. It means that one small thing can drastically change everything. Bacteria also make vaccines & when something dies, plant or animal, bacteria is what decomposes it.When things are rotting, its just bacteria releasing carbon & other important nutrients out of the dead organism and into the air and soil. They also decompose compost and sewage which helps create methane. If bacteria didn't exist, the waste would just keep accumulating at record speed and interfere with the existence of everything living on earth. Plus decomposition returns carbon dioxide into the air which enables plants and the rest of the world to survive. This natural recycling process returns minerals to the earth and makes it fit for plants and animals to live.
So yes, we do need bacteria, no matter how bad some of it can be.
