CO2 is plant food. The US makes enormous amounts of plant food. The Left -- you know, the people who are so worried about starvation in the Third World -- are really upset that we produce so much plant food.
You are exactly correct. The left is pissed that our country has so much fertile land and so many smart farmers. So, the left has to work extra hard to interfere with our food supply...all in the interest of pulling our country down.
