On the harm of fluoride
There are things in the world. Its name is fluoride. Although it is small and harmful, it cannot be ignored.

In the past, people did not know the properties of fluoride, but they used it carelessly, causing harm gradually. Fluoride can enter the body and damage the muscles and bones. The disease of looking at the teeth is mostly due to fluoride accumulation. In the beginning, people used fluoride-containing agents to protect their teeth, but they did not know that if they were used too much, it would be harmful. Fluoride is concentrated in the teeth, and the color of the teeth changes, mottled like rust, and even the teeth are brittle and easy to fold.

And the harm of fluoride is not only the teeth, but also the bones. Those who have been exposed to fluoride for a long time will gradually harden and brittle, and People who work depend on the strength of their muscles and bones to make a living, but they are invaded by fluoride. Their strength declines and they become waste, and their lives are difficult.

And fluoride in the environment is also a disease. Fluoride-containing substances are discarded in the field, seeping into the soil and sewage sources. Water is the source of life, and fluoride enters it. Humans and animals drink it, and it is harmful from the endogenous. Crops in the field absorb fluoride in water and soil, and their quality changes. If they eat it, it will be harmful to the body.

Investigate its source. The harm of fluoride originates from the excessive use, and the detection is unknown. If you want to get rid of this disease, you should understand its nature and use it carefully. In industry, control the discharge of fluoride, do not pollute the world; in people's livelihood, publicize its harm, and teach the people to carefully choose fluoride-containing products. In this way, fluoride harm can be reduced, people's well-being can be ensured, and the world's peace can be protected.
