Humans burnt 100’s of millions of years of plant growth within 100 years. There is no way we can significantly reduce the CO2 in the atmosphere with plants alone in a timeframe that is necessary for humanity to see a difference. There is just not enough land to plant that many trees and plants. We need all the solutions and that includes human tech.
But it is not a solution. Carbon capture is the perfect thermodynamic example of sweeping the dirt under the rug. Best case scenario it would alleviate the problem now to make the problem worse in the mid term. Most realistic scenario it will do nothing at all.
We currently do not have a human tech to support the process. The only thermodynamically meaningful process is transformation of CO2 in safe and useful organic compounds. But all our technology is too expansive, and requires a lot of energy, production of which is currently one of the main responsible for emission of CO2
