Gao Wu: Become a God Starting from the Plant System

Regarding the destructiveness of plants to the earth's ecology, I only mention two geological events: The end-Devonian mass extinction that wiped out 80 to 90 percent of the species on the earth at that time, and the Azolla incident that dragged the entire earth into the Quaternary Ice Age. The direct cause of both extinction events was plants. During the Devonian period, "trees" with lignin appeared. They use photosynthesis to fix carbon dioxide, and these carbon elements will not return to the atmosphere when the trees die, but will become oil and other materials and remain underground forever. The lack of large amounts of greenhouse gases caused the earth's temperature to plummet, eventually leading to an extinction event. The basic logic of the Azolla incident is similar, except this time it is replaced by aquatic ferns. At that time, the Arctic Ocean was more closed than it is now, and the earth was hotter than it is now. As a result, with the confluence of many freshwater rivers, the surface of the Arctic Ocean has almost become a super-large freshwater lake. Azolla, a plant with a growth cycle that resembles a breeding body, likes this kind of environment, so this creature almost accomplished a feat of destroying the earth's ecosystem in the Arctic Ocean, dragging the earth into the Quaternary Ice Age. We humans are the representatives of ice age species. Don't let the protagonist destroy the earth again.
