Detailed explanation-1: -Other strong bases such as soda lime, sodium hydroxide, potassium hydroxide, and lithium hydroxide are able to remove carbon dioxide by chemically reacting with it. In particular, lithium hydroxide was used aboard spacecraft, such as in the Apollo program, to remove carbon dioxide from the atmosphere.

Detailed explanation-2: -A carbon sink absorbs carbon dioxide from the atmosphere. The ocean, soil and forests are the world’s largest carbon sinks.

Detailed explanation-3: -Fortunately, the amount of carbon stored in wood is a straightforward calculation that remains consistent for each wood species. As a tree grows, it absorbs carbon dioxide from the atmosphere, stores the carbon in its wood fibers, and releases the oxygen back to the air through the process of photosynthesis.

Detailed explanation-4: -The United States has 766 million acres of forestland, which absorb nearly 16 percent of carbon dioxide emissions per year. Forests sequester (or absorb) and store carbon dioxide from the atmosphere, helping reduce greenhouse gas emissions.
