In your picture you are missing the part where CO2 is the fundamental compound to create life on earth, as it is the source of carbon to “create” all living beings, as well as fuel and oxygen source needed for many of them to live.

Carbon capture is extremely expensive and inefficient, because it is thermodynamically disfavored. In the big picture ineffective, because we need to transform CO2, we don’t need to bury it. The solution is to reduce the amount of excess of CO2 released, and increase the processes that transform CO2
