Look up OSHA health standards for working in environments with elevated CO2. I can tell you what they are, but if you are skeptical, seeing it for yourself will help. Last I saw, worldwide CO2 levels were listed as 417 parts per million, botanist say that's at the low end for what plant life needs to exist (300 ppm is the bottom level that plants can survive). I did gas measurement for years, and we never measured CO2 at a specific level, in real science it is always expressed in a range, for example 300-350 ppm. It's a gas, and gases are not uniformly distributed in the atmosphere. Bottom line- CO2 is essential for life. As the CO2 fraud is exposed, they are changing tactics and claiming manmade water vapor is causing climate change too. Problem is when water vapor reaches certain levels it precipitates. It's all about power and control, fearful people are the easiest to control.
