what does scientists think caused all the gases to come into this world

why does photosynthesis help in decreasing carbon dioxide

in photosynthesis the equation is : carbon dioxide + water = oxygen + glucose so the more plants there are in this world the more the plants are taking from the carbon dioxide and making more oxygen
