A model has been proposed to secure a sustainable planet by initiating phototrophic energy (Pte) and chemotrophic mechanism (Ctm) to address the global CO2 and the environmental pollutants. As the hypercharge electron of the phototrophic energy (Pte) is the striking force to release kinetic energy, the implementation of this energy has been implemented on the global vegetation to break the CO2 naturally. Subsequently, the chemotrophic mechanism (Ctm) that obtains food from the oxidation process from the inorganic and organic pollutants has been analyzed computationally to clarify how the chemosynthesis process eliminates all pollutants from the earth. Simply, the implementation of phototrophic energy (Pte) to break atmospheric CO2 and the initiation of the chemosynthesis process (Ctm) of the chemotrophs to clean up the global environmental pollutants naturally shall indeed be an excellent finding in natural science to secure a sustainable environment for the planet earth.
