Global environment is formed as the result of physicochemical reactions of the matters in Nature. The behavior of the substances can be elucidated by the chemical knowledge. By the solubility of chemical species in water, the behavior of those can be clarified. For example, carbon dioxide spread all over the world, while the acid rain can reach only 500-1000km from origin. Global warming is well understood by the infrared absorption of the green house gas molecules such as CO2, CH4, N2O etc. We can understand stability of substances by using bonding energy.
