Answer:speciation
Explanation: Speciation is the evolutionary process by which populations evolve to become distinct species. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another these are allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.
It would disrupt the CO2 cycle, since plants would no longer absorb carbon dioxixde, nor let out oxygen meaning it would also provide animals with little oxygen, and they can’t produce CO2 then either
