The Great Dying happened 250 million years ago, and in that period, almost the entire life on Earth has been extinct. The Great Dying was caused by greenhouse gases in the atmosphere, a similarity that scientists see once again in the present. Our atmosphere is going through some changes and scientists are showing them in a new exhibition at the Smithsonian National Museum of Natural History from Washington, D.C.
The theme of the exhibition is the connection between life and geological time and facts. The display is showing how the plants which are at the bottom of the food chain have a significant role in supporting life, starting with the insects and going to the prominent species. The insects, for example, where the ones that have shaped the forests and help them evolved over millions of years, so life is supported from bottom to the top. If something big is happening on Earth, the whole fabric can be destroyed.
Today We Are Having the Same Factors as the Great Dying that Killed all the Life on Earth
Looking back to the Great Dying, 250 million years ago, everything went wrong when a volcanic eruption in Siberia from now has been coated the atmosphere from the lava that burned the areas. Because of this reaction, the atmosphere was filled with carbon dioxide and pollution. The result is simple, the carbon dioxide is filling the atmosphere, and the planet gets warmer. If the Earth has become warmer and warmer, the Oceans have become acid, and there is no more oxygen.
Because of that, more than 90% of species from the Oceans have died, and two-thirds from the ground as well. This extinction was not the same as the one that has wiped out the dinosaurs. This extinction was in the Permian Period and was caused by the carbon dioxide in the atmosphere.
To sum up, scientists have seen the similarities between what happened 250 million years ago, and what is happening now because of human activities. The planet is getting warmer and warmer, and this will lead to the same event from the Permian Period, even if it happens gradually. The idea will be the same, with a lot of species dying first, especially in the cold parts of Earth. The similarities between the Great Dying and today are relevant, so this is a message that needs to be heard.
Karen and her husband live on a plot of land in British Columbia. They aim to grow and raise a significant part of their food by maintaining a vegetable garden, keeping a flock of backyard chickens and foraging. They are also currently planning a move to a small cabin they hand built. Karen’s academic background in nutrition made her care deeply about real food and seek ways to obtain it. Thus sprung Anna’s interest in backyard gardening, chicken and goat keeping, recycling and self-sufficiency.
