So why is it not a good idea to reduce carbon dioxide to 100 ppm?

Plants would starve at much higher ppm than 100 ppm.

Think you meant lower, not higher. Plants in greenhouse, with 1200-2000 ppm, do incredibly well. Think this point alone, is a 'Climate Change' deal breaker. More warm and CO2 would benefit plant greatly, which produce more food for the planet. The obvious though, is that reduce the CO2 is going reduce the available food, more than the potential of the average global temperature rising a few degrees. There are a lot of warmer climates around the world, and people survive just fine.

Thus, we can say that, as a rough estimate, the value (where plants die) lies between 50ppm and 170ppm (probably closer to 170ppm than to 50ppm).

I don't know if anyone has ever tested where they actually die, but according to the studies they have done, the graph shows it to die somewhere between 50 and 170. Every sign says its closer to the 170. Since that range is 120 ppm half way would be 110 (50+1/2 of 120). Since all the study say its most likely to be above the 110 ppm, no, its not likely to below 100 ppm.

What I meant is that if co2 ever hits 100 ppm, its likely all life on earth will have died.

Photosynthesis ceases at 180 ppm. Plants cannot absorb enough CO2 to live at that level.
