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 known as the red planet. The planet itself is mostly rock. It is the thin atmosphere that is mostly carbon dioxide.
Earth, Mars and venus all have nitrogen and Carbon dioxide in their atmosphere, though the levels vary from planet to planet.
Venus
Venus has a thick carbon dioxide atmosphere, making up about 96.5% of its atmosphere. This high concentration of carbon dioxide contributes to the intense greenhouse effect on the planet, resulting in surface temperatures hot enough to melt lead.
Venus is the planet that is dominated by carbon dioxide, with its atmosphere consisting of about 96.5% CO2. This greenhouse gas contributes to the extreme heat on the planet, making Venus one of the hottest in our solar system despite not being the closest to the Sun.

Venus has an atmosphere that is 96.5% carbon dioxide, making it the planet with the highest concentration of carbon dioxide in our solar system.
the atmosphere of palnet venus is mainly contained by; carbon dioxide and a small amount of nitrogen.
Mars is known as the red planet. The planet itself is mostly rock. It is the thin atmosphere that is mostly carbon dioxide.

Venus
Without carbon dioxide and water vapor, we would be a cold dead planet. Oxygen is needed for the life cycle, as is CO2. When something dies, that co2 is returned to the atmosphere through burning or decay.
The more carbon dioxide the hotter the planet gets. The hotter the planet gets the more wild fires happen. For every fire that occurs more carbon dioxide is released.
