It's not even breathing that's the problem, it's the claim that higher CO2 is great for plants. It can be, however the plants that grow from higher CO2 levels (particularly crop plants) produce their plant mass differently than with less CO2 unless compensated for, like in a controlled greenhouse. Directly because they are getting a different ratio of nutrients and gases.
Add that to all the other factors that threaten food supplies thanks to warming. Someone at some point saw that plants get green at high CO2 levels and thought it would work as an argument against climate change, not understanding the details (or not caring because it suits their purpose).
Also, plants don't grow well in floods, or when on fire, or in 50° C.
Flooding and fires are in fact exploited by many plants, even necessary for some.
Oxygen is necessary for animal life.
It can also explode.
Also, faster and more voluminous growth =! better quality growth. See: new vs old growth lumber.
Are humans not part of "All life on earth"?
Not for much longer.
Yes, but plant growth reactions to higher CO2 happen at much lower levels of increase than your example of being harder to breath.
