Will there be a lot of bacteria on your body after passing through a garbage dump?

There are a lot of bacteria, viruses and various harmful substances in the garbage dump. Of course, there is no need to make a fuss. If you pass by a garbage dump, generally speaking, the impact is relatively limited. Of course, if you often live near a garbage dump, the impact on your health will be relatively large. The air near the garbage dump is bound to be polluted to a certain extent. It is easy to induce the occurrence of some diseases.

Bacteria are a large group of invisible microorganisms that often move around us.

Bacteria can be found in the air, water, soil, garbage dumps, on the bodies of animals and plants, and in dark and damp corners.

When you hear the name bacteria, don't think that they are all bad guys.

Some of them are good friends of humans!

Like yeast, it is a little technician of fermentation.

It has a special set of abilities. Once it falls into sugar juice or fruit juice, at the appropriate temperature, it will break down sugar into alcohol and carbon dioxide, helping to make wine. Some bacteria are active in the soil. For example, decomposing bacteria can decompose proteins in manure and dead animals and plants, turning the proteins into nitrates to meet the needs of plants. It also has lactic acid bacteria that ferment radishes, cabbages, etc. to make sauerkraut. Because these bacteria are beneficial to the body, they are called probiotics.

The other part, the bad guys that specifically make people sick, are called germs.

How did you find out later?

The microscope helps.

Microscope is the eye of science. It reveals the secrets of the tiny world and allows people to see the activities of bacteria. So, who invented the first microscope?

Johnson's father was an optician. As a teenager, Johnson loved playing at his father's workbench. Once, he put two polished lenses in a copper tube and used it to read the words on a book, and the words became very large. He told his father about this, and his father was very happy. He made the first microscope according to his device.
