I sit in a hot office and think about this. I am not sure where to ask. I am genuinely curious. I have seen a breakdown of building solar panels to power the earth 2x over in order to recapture carbon equal to the rate it is being produced, but then areas of the earth that were reflective are now absorbtive of heat…
Sewage has a lot of carbon. Separate sewage like we do ewaste and store the tonnes of carbon. Let plants and other food get from the air.
