Rant in a totally different direction. Carbon Capture Is Not Sustainable!
Unless you can capture 1 ton of carbon using less energy than is extracted by burning 1 ton of carbon, you can not capture carbon. Carbon capture will ONLY work if the energy you use to capture the carbon does not add more carbon to the atmosphere (nuclear, wind, solar) but having to run a supplementary power generation tech just to negate the effects of your primary tech is just stupid, fossil fuels no longer a viable option.
Pedantic, but you can do this by planting a forest (in a currently not forested area).
No, you can't. There are trillions of trees on earth and the impact they have on carbon emissions is relatively minimal, planting a forest or even many forests isn't going to cut it.
Not to mention that for trees to be an at all viable long term carbon capture method, you can't ever cut those trees down. If we can't leave the fucking Amazon alone, what makes you think we won't chop up that artificial forest in 50 years?
This is the same issue with kelp. Kelp has a ton of uses, and is an even better carbon sink than trees are, but to be a carbon sink you have to forgo all of those other uses because you have to literally sink the kelp to the bottom of the ocean and leave it there, because actually using it for anything just rereleases the carbon.
You can cut down the trees and they'll still hold on to their carbon. Just don't burn them.
Not all cut timber is used for burning. Paper is still manufactured, along with strand board, particle board and plywood.
Not practically. You'd have to be replacing the trees faster than you chop them down just to account for the energy(and thus carbon) used to chop them and process them. Then there's the fact that decomposition will also release the carbon, so you HAVE to use the lumber for stuff that is intended to last at least as long the tree grew, or else that tree is still a net negative.
