[This oxygen content is a feast for the evolved insects, amphibians, small vertebrates, etc. If the planet's vegetation and ferns are very tall and lush at this time, they will definitely evolve into large animals and stabilize the balance of the planet's carbon cycle with the consumption of predators.]

[But unfortunately, nature has no if. From the time when the Muba people were dissatisfied with the sunlight being blocked by volcanic ash, they waved their upper limbs and rushed towards the primeval forest, Mars was destined to be unable to appear taller than the Muba people.

Without large vegetation, animals that evolve towards large-scale transformation would starve to death, and large-scale transformation animals would be destined to be unable to appear. Without large-scale transformation animals, no one could threaten the Muba people at that time.]

【The carbon cycle collapsed...】

[A large amount of carbon-containing gas is absorbed and solidified by vegetation, and then buried underground as the vegetation dies. The natural decomposition and occasional forest fires return atmospheric carbon, which is simply unsatisfactory for the vegetation and Muba people on the entire planet, and the carbon content of the air has dropped below 0.005%.]

[The Muba people are photosynthetic life. Only three kinds of things are needed to maintain Muba people's life activities, water, carbon gases, and sunlight.]

[The Muba people started a war, just like the previous battle for sunshine, they launched an extinction war on all the vegetation on the planet!]

[They have evolved initial wisdom and know that these vegetation is absorbing carbon gases in the air just like themselves. If they kill them, they can obtain more carbon by themselves.]

[This is a war that has nothing to do with good or evil, only about survival, only about evolution, the advantages and disadvantages of evolution. The winner continues to reproduce and inherit, and the loser's extinction of species becomes history.]

[The pheromones of the Muba people spread in the air, and this war of extinction quickly spread to the world like a pot of fire cooking oil!]

[Muba people used their more flexible upper limbs to lift up the shallow vegetation, so that they could be completely exposed to the sun to death. When they encountered trees with relatively developed roots, they would slowly strangle them with thicker moving roots!]

[Other vegetation cannot resist the extinction war launched by the Muba people at all, and insects, amphibians and small vertebrates do not understand what happened...]

Pieces of vegetation were killed by Muba people, and pieces of animals died because of lack of food. Through the screen, Lu Yi and the others seemed to smell the rotten smell emitted by the rotten animals covering the entire Mars.

"True kindness, we humans are really kind!"

Professor Hill looked at the scene playing on the screen and couldn't help but open his mouth and said with a shocked expression.

Everyone believes that vegetation is the producer and the foundation of the environment. The amount of vegetation represents the advantages and disadvantages of the environment, but they do not realize how terrifying the disaster that will be caused will be once vegetation that uses photosynthesis as the energy source.

Predators evolved into smart races. Because predators need to rely on the environmental ecosystem to survive, they will at most cause the extinction of a small number of species during their evolution and reproduction. Even when civilization develops, they will maintain the environment and maintain the diversity of species.

But once producers evolve into intelligent life, they do not need to rely on ecosystems to survive, and they can slaughter all non-parent species at will.

Although the Muba people are not plants, but life before plants and animals differentiate, their positioning in the environment and vegetation, which uses photosynthesis as the energy source, are not different from vegetation in the environment, and they are both producers.

When they completed the planet domination and gave birth to wisdom, the evolutionary history of human beings, the destruction of the environment and species by terrifying erectus apes, is not even a fraction of the Muba people's behavior of slaughtering the world.
