Yep, we are currently at 0.04% CO2 in the Atmosphere. Not 4%, not 0.4%, but 0.04%.
If that number falls below 0.02%, plants cannot survive, and thus Humanity itself can't survive.
The CO2 ratio has also been much higher in the past, because of various volcanic eruptions.
The threshold limit value for CO2 in the workplace is 5000 ppm for an 8hr day, 40 hr week. For much of Earth's history, CO2 has been in the thousands of ppm, with plenty of life flourishing here.
