Yes, burning fossil fuels is really inefficient. We should stop doing that. We have better options now.
And, climate models say we need to remove 10 billion tons of carbon dioxide from the air every year in 2050. It's really inefficient but there's already too much carbon dioxide in the atmosphere.
It takes a lot of energy to pull carbon out of the air. The energy needs to come from somewhere, but if it involves burning oil then it's going to create more mess than it cleans up.
