We humans all live on the same earth, and only the earth is suitable for us humans to live in. The earth provides us humans with suitable temperature and moisture. All the planets in the world cannot meet our needs for human survival. Necessary, so the earth is the only home for us humans. So many people will ask, who were the first overlords on earth? When we look at it, I think it’s those tiny bacteria and various microorganisms.

On the earth where we humans live, there are many life forms. However, the existence of each life form is also a choice of nature. There are not only animals and plants, but also a large number of living organisms. Therefore, in our natural environment, there are many living things living with us. However, life is only once for each of us. Cherishing life is both a responsibility and an obligation. We are obliged to protect it. Take care of your own life, just like the earth we live on. Without the earth, life will disappear.

The first overlords on the earth are actually the bacteria and microorganisms that often appear around us. Although these bacteria are small in size and often invisible to our naked eyes, they The harm to us is very great. For example, those microorganisms that are more harmful will not only cause great harm to our human body, but also seriously affect our natural environment. We can survive in society. In fact, the impact of the natural environment is very big.

The tiny bacteria around us are often found in food, and most foods have a shelf life. If the food goes bad over time, there will be A lot of bacteria are produced. However, if people accidentally eat this kind of spoiled food, it can easily endanger the health of the body, and even cause cancer in severe cases. So now more and more people are suffering from cancer around us, so we will say that these bacteria And microorganisms will become the overlords on earth.
