    “Easier”? Are you aware of the fact that radioactive waste tombs are meant to stand for millions of years? It requres a lot of territory, construction and servance charges, and lots of prays for nothing destructive happens with it in its “infinite” lifetime.

      Have you tried capturing gas? As difficult as radioactive waste tombs are, they’re easier than containing a specific type of air lol.

        Read about breathing if you want to know how to capture gas. Also, about photosynthesis.

          If you want to buy the land to plant a second Amazon, be my guest. And breathing does the exact opposite of what we want.

              You need a lot, lot more trees. Like several orders of magnitude. And growing trees takes longer than even building a nuclear power plant.

                To be specific, growing the types of trees we would want for such a thing in such an amount that it would deal with the problems we have, assuming we stop growth of CO2 and assuming we stop burning the Amazon, would take around a hundred years.

                https://www.nationalgeographic.com/environment/article/how-to-erase-100-years-carbon-emissions-plant-trees

                “It could take more than a hundred years to add enough mature forest to get sufficient levels of carbon reduction. Meanwhile 40 billion tons of carbon dioxide (CO2) from burning fossil fuels are being added to the atmosphere every year, said Glen Peters, research director at Norway’s Center for International Climate Research.”

                And need an area the size of the United States. I wasn’t joking about a second Amazon.

              I’d rather this as well, but we don’t have that many choices. The slower we act and the more we let perfect be the enemy of good, the more people die.
