It's also important that these trees not be allowed to die and decompose. The decomposition of trees will just put all the captured carbon back into the atmosphere. Dead trees need to be buried underground, or forests planted specifically with the intent to be cut down and eventually and buried underground. Or, even plankton farms created specifically to be harvested and buried.
Ultimately all of this isnt profitable, and thus wont be created at scale. I suspect we need to start making energy providers be required to bury Carbon as part of running their business!
CO2 from the ground in the form of oil, gas and coal (etc) goes into the air. CO2 from the air goes into trees. CO2 from dead trees goes into the carbon cycle. We need to remove carbon from the cycle. It is definitely part of the issue. Hence by stating that it might be a good idea to make forests specifically for the farming of carbon.
If you can think of another way to gather carbon cheaply and then get it out of the cycle I'd be happy to hear it!
