So, the question I put to you is this: After reviewing the information above, and perhaps doing your own research, what would be the ideal concentration of CO2?

537 parts per million. But maybe 1000 ppm would be better still. With that much CO2, athletes would not be able to beat records set when there was less CO2. Suffocation is not so good for aerobic exercize extremes. Actually, that might not make all that much difference because CO2 in exhaled air is about 5% so going from 0.04% CO2 inhaled to 0.05% inhaled is trivial compared with 5% exhaled = 100 times as much CO2 going out as coming in.

Plants would go crazy!! Not up to the joys of the carboniferous times at 1600 parts per million but still quite fun for the chlorophyll crowd.
