I did ask you and your response was not clear.
OK, the first link says:
It ignores the considerable benefits of atmospheric carbon dioxide in promoting the growth of plants, advancing agriculture, and lowering the cost of food for a growing world population.
1. Higher levels of CO2 in the atmosphere do not significantly contribute to crop production.
2. Higher levels of CO2 in the atmosphere does not 'advance agriculture'.
3. Because of 1. and 2. it doesn't lower the cost of food.
4. How is 'a growing population' relevant? This must be an appeal to the myth that the worlds population will outstrip food production. The reality is the food production depends on demand and pricing. There is no major shortage of available land or production capacity for food crops.
If you really want to improve farming, there are many many ways to significantly increase the production that a given farmer can achieve. The down side is that only a finite amount of food can be consumed, so every time you increase one farmers production, you are putting another farmer out of business.
