The rarest vegetation on earth, much like a magical and strange alien planet, is extremely fragile

Iceland is a magical country, which is called the closest place to the outer planet. Because of its proximity to the Arctic Circle, the vast expanse of land is frozen by glaciers, so Iceland is also called "frozen land."
It's like the end of the world, the ancient planet. The natural-growing 15kg suitcase trees in Iceland are rare, but the trees are all over the moss. These seemingly insignificant moss are actually the mysterious creatures that make Iceland different. Because of these fine moss, the most rare "a behemoth" of the earth, the tundra, has grown in a long time after the millennium.
The tundra mainly refers to a vegetation composed of mosses, lichens, perennial grass and cold-resistant small shrubs in the Arctic Circle and in temperate and cold temperate regions. As a typical cold-band ecosystem, the tundra is distributed in the northern edge of Eurasia and North America to form a substantially continuous tundra.
Therefore, tundra, also known as tundra, is a biological community growing on cold permafrost, a biological community in extreme environment. So tundra is very rare and usually appears only in geography books 15kg bag size or papers. In Iceland, one can see the vast tundra belt, as if into a magical world, strange and spectacular.
In polar climate, tundra is the most common and common vegetation form in Iceland, one of which is mossy lava, as the name implies, volcanic lava is full of bryophytes, that is to say, volcanic lava is wrapped in bryophytes.
The tundra, which is covered on the volcanic rock, can usually be accumulated to a thickness of 20 cm. When the tundra is to be touched by hand, the texture is soft and soft as an air-cushion bed full of elasticity, so that you have an impulse to roll over it. It's like stepping on several soft and thick carpet, and it's very comfortable.
However, large-scale tundra is made up of many small tundra vegetation, they themselves are very vulnerable, a little bit of hard stepping will crush its small life, geomorphological restoration may take decades or more. As a result, in the vast tundra, people inadvertently destroy tens of millions of tiny creatures.
Therefore, Icelanders pay great attention to the protection of these hard-won tundra, tourism websites and newspapers often warn tourists not to stampede on the tundra. In the past few years, however, there have been more and more Icelandic tourists and tundra has been damaged to varying degrees. Justin Bieber, a popular singer, angered and condemned Western netizens by letting actors dance frantically and even set off fireworks on tundra in his MV.
