One of the strange phenomena that occurred in Siberia is a large crater that continues to grow every year that is crater Batagaika.
According to the researchers this enormous Hole appears above Permafrost and includes the largest crater in the region.
By the local people, this crater is often called the 'crater of the gates of hell' because it continues to grow annually!
Recent research conducted by Frank Gunther of the Alfred Wegener Institute in Germany says that: "The crater wall is increasing every year."
The researchers also mentioned that the hot weather will make a lot of ground around the crater will collapse. And that is a bad news for world climate change.
"What I'm worried about is getting bigger and deeper in this crater, the carbon in the bowels of the earth will come out, the impact of this world will get hotter." Frank said.
May we as human beings are given more sense to keep the earth better for the future of human civilization in the future, what do you think?
