it's delicious to visit the selenium-enriched landscape and taste the selenium-enriched food. Hey. Nature has endowed human beings with selenium-enriched minerals and selenium-enriched soil, and farmers' uncles planted crops in selenium-enriched soil, and the crops produced are rich in selenium, a mineral element, hence the name selenium-enriched food. Selenium-enriched food is absorbed by human body after being swallowed by digestive organs. It is said that health is greatly good, and this great good has become the knowledge of all mankind. Since it is so kind to human beings, human beings should not forget the well digger. Who is this well digger? That is nature. In view of this, people should fear nature, how to fear it? How can people live in harmony with nature? People must take practical actions to protect the ecological environment. Otherwise, the ecological environment has been artificially destroyed, and then, selenium-enriched agricultural products will be turned into black? What a pity!
