Microalgae are a benefactor of creature prosperity in the earth|
The earth was created as a lump of heat about 5 hundred millions years ago. After that, there was a origin of the plant which has a chlorophyll and photosynthesis ability (absorbed the sunlight and using the water and carbon dioxide, produce the oxygen) about 2 hundred millions years ago, and this creature was Microalgae. Owing to the Microalgae, the oxygen supplied to the earth first time, and it makes the chance to appear the oxygen breathing creature.
But at this time, it poured so strong ultraviolet rays that any creature can not live. And then, the ultraviolet rays was reduced cause of a part of oxygen which Microalgae produced, changed to the ozone and accumulated in the air. This way, the earth became a proper environment for the creature to alive and then, various creatures include human appeared like now. The origin of Microalgae, after that, has done various evolution and bear severe environment change like a glacial epoch, and now there are many kinds of species. Where is strength of the vitality? Anyway, because Microalgae hide the strong vitality, it can contain the effective substances for human.
