Before bacteria evolved photosynthesis, there was hardly any oxygen in the atmosphere. Now oxygen is the second most abundant gas in the atmosphere at 20%. Most of the other gases in the atmosphere is nitrogen (78%). Carbon dioxide level is only 0.3% currently. It shows how important it is to the atmosphere to have photosynthesis. If the rate of photosynthesis increases there will be more oxygen and less carbon dioxide because photosynthesis turns carbon dioxide into sugar and oxygen.

Didn't you like the answers you got the last time?
Or maybe you didn't understand them.
Increasing the rate of a reaction decreases the input reactants and increases the products.
The input reactant is atmospheric CO2, the product is carbon (sequestered into the plants) and atmospheric O2.
