Why would billions of people necessarily die? Plants thrive on CO2. More carbon dioxide, more plants, more plants, more food.

First of all I did not say die, so quit misrepresenting what I say. Billions will not thrive.
Ocean levels rise, billions displaced. Agriculture will be fundamentally changed. Where something grew well before it might not in future. Do you know anything about wheat? Rapeseed? Corn? How about trees?.
More carbon dioxide, more plants, more plants, more food.
You really dont have much more than simple thoughts do you. No more CO2 does not mean more plants and if it does more plants does not mean more food.
