H202 is the symbol for hydrogen peroxide which has one more atom of oxygen than H20. All things have atomic structure that varies in makeup.
When exposed to other matter H202 is changed from its stable composition. An extra oxygen atom is released leaving H20. In nature, oxygen, or O2, consists of two atoms in a stable combination. Plants and vegetation also produce oxygen, but a single oxygen atom is highly reactive and is called a free radical.
H202 in rainwater makes it beneficial for plants than ordinary tap water which contains high concentrations of aluminimum and chlorine due to the sanitizing processes of municipal water supplies. Increased levels of atmosphere pollution cause greater amounts of H202 to react with air borne toxins, the result being that fewer H202 atoms reach the earth because they lose one atom. The result is more H20. Vegetation and plant life suffer as a result. It is likely that H202 was abundant in ground water prior to the flood. Today underground pollution of water aquifers has also robbed it from those sources.
The ozone layer that surrounds the earth consists of three oxygen atoms. The protective layer is created when ultraviolet light from the sun splits an atmospheric oxygen molecule into two single, unstable oxygen atoms which combine to form ozone which is only partially stable. Ozone will give up the extra atom of oxygen to falling rainwater creating H202. When pollution interferes with the natural cycle put in place this causes ozone depletion.
When something is altered in nature it causes imbalance in the life cycle. When this imbalance is corrected, the earth will once again thrive.
