We DO have as much CO2 on Earth, just not in our atmosphere. The majority of Carbon Dioxide on Earth, is locked away in our crust, both and land and under the oceans. Were this to be released, there would be a runaway greenhouse effect, like on Venus, however, this is hardly possible. Mars on the other hand, has most of it's CO2 in it's atmosphere and polar caps.

Life and H2O have moved almost all of the CO2 that was once in the Earth's atmosphere into the oceans and rock. Life, mostly in the form of small plankton like creatures in the oceans, stores CO2 in its bodies and then carries it to the bottom of the oceans when the creatures or plants die. Water carries CO2 out of the atmosphere and conveys it to mineral deposits and the water in the ocean stores large amounts of CO2 in solution (the oceans are slightly carbonated).

Plants converted CO2 to oxygen by photosynthesis.

We have plants and photosynthesis to recycle our air. Mars doesn't.
