I responded in more detail above, but you’ve actually got it backwards.
Plants that where/are better at making use of the atmosphere as it is, will be the ones that thrive. If the atmosphere was different, different plants would exist.
Our atmosphere is the result of plant evolution; not plant evolution a response. There were (and to an extent are) plants that evolved in a different atmosphere. And they almost all got wiped the fuck out once oxygen photosynthesis evolved. Many plants and bacteria still keep the hardware and software around for doing this work, but its way fucking trickier than it used to be, because oxygen.
