The last time atmospheric carbon dioxide levels were as high as they are today (approx. 380 ppm (parts per million)) was around 15 million years ago, during the Middle Miocene period, when carbon dioxide levels are calculated to have been around 400 ppm.
During that time there was no permanent ice in the Arctic and very little over Antarctica or Greenland. On top of that, sea levels were between 75 and 120 ft higher than they are today and world temperatures were higher by between 5 and 10o F.
Today the average concentration of carbon dioxide in the atmosphere is approx. 4oo vpm; some scientists consider that values over 300 ppm are high.
Because you might not be able to breathe in the high or low carbon dioxide because it really depends if you are use to it or not but you maybe be able to take it for other reasons.

Just as the earth has naturally-occurring carbon dioxide in its atmosphere, so also does the planet Venus have naturally-occurring carbon dioxide in its atmosphere. Because the concentration of carbon dioxide is so high in the Venetian atmosphere, it has a more considerable greenhouse effect.
Capnophiles are microorganisms that thrive in environments with high levels of carbon dioxide (CO2). These organisms have adapted to utilize CO2 as a source of energy or require it for their growth and survival. Some examples of capnophiles include certain types of bacteria and archaea.

We breathe out carbon-dioxide because high levels of carbon-dioxide in the body can be toxic By Akhilesh Sharma
well, you don't breath carbon dioxide, you breath oxygen
The suffix -capnia refers to conditions related to carbon dioxide levels in the blood or tissues. It is commonly used in medical terms to indicate conditions such as hypercapnia (high carbon dioxide levels) or hypocapnia (low carbon dioxide levels).

Smoking increases carbon monoxide levels in the blood as opposed to carbon dioxide. Carbon monoxide ties up hemoglobin so that smokers have lower blood oxygen levels. Chronic inflammation has been linked to the high levels of carbon dioxide that smokers breathe in as it is 200 times the atmospheric rate.
It is Venus.
