Plants remove CO2 from the atmosphere

but they don't keep it

Therefore, to remove carbon dioxide from the atmosphere, you ned to:

  • Add energy to evely single molecule,
    even at very low concentrations
  • Transform it to something else that not let it out
  • Store it away from the atmosphere for a very long time.
  • Do this cheaply, preferrably with some gain.

Plants can do almost everything of this

Except that they die after some time, and then the carbon dioxide is released into the atmosphere again

  1. The standard operative level of carbon dixoxide for plants is the same as the atmospheric level.
  2. They transform the CO2, not only stove it away.
  3. The products are clearly useful carbhydrates
    (/CH2O/n for short), as wood, sugars and the like.
  4. They do all this with solar energy.
    No fossil energy is needed.

Carbon dioxide plus water (plus sunlight)
gives carbohydrates plus oxygen

However, when plants die, the reaction goes backwards.

The carbohdrates decompose to water and carbon dioxide again.

Animals (as you), do the same with plants

It doesn't help if you plant a whole forest.
  • A single tree has its growth phase, its middle age and its scenecence.
    • During its middle age, it takes up the most CO2
  • It is the same with an entire forest. When the forest is mature, the respiration rate equals the photosynthesis rate
    • No further CO2 is absorbed
    • A lot of CO2 is absorbed as biomass, but all further routes points down
But there is a way out of this problem... Back to the Carbon page
