The carbon cycle on earth moves carbon dioxide in and out of the oceans, air and land so there is a regular amount in the atmosphere. This amount has been steady at around 280 ppm (parts per million) for thousands of years, and it traps sufficient heat in the greenhouse effect to keep the earth warm enough for life.
Since the Industrial Revolution, about 250 years ago, when we seriously started burning fossil fuels (coal, oil and natural gas) levels of carbon dioxide have been building up in the atmosphere so now the level is at 400 ppm. This is causing global warming.
Mars is the terrestrial planet with a thin carbon dioxide atmosphere. Venus also has an atmosphere of carbon dioxide, but it is very thick.
Such an atmosphere on a planet would be the result of carbon dioxide emitted from volcanoes.
Venus has the thickest carbon dioxide atmosphere.
Earth, Mars and venus all have nitrogen and Carbon dioxide in their atmosphere, though the levels vary from planet to planet.
Mars is known as the red planet. The planet itself is mostly rock. It is the thin atmosphere that is mostly carbon dioxide.

carbon dioxide
Too much carbon dioxide in the atmosphere, as we have now, 400 ppm (parts per million) or 0.04% instead of the regular 280 ppm that we've had for thousands of years, is the cause of global warming. This is very bad for the planet.
Venus and Mars both have atmospheres dominated by carbon dioxide. Both are composed of more than 90% carbon dioxide.
