The book would offer a historical basis from acid rain, ozone depletion, to the current increase in CO2. By offering this perspective, the book provides chemical solutions to acid rain and ozone depletion. A new approach is proposed other than a straightforward chemical concepts book, but also offer short highlight topics on the politics involved and arguments against these environmental crises. Readers will learn to derive molecular orbitals, gain understanding in group theory, and apply these concepts to reactivity and molecular spectroscopy. The topic allows for continual development of the textbook by introducing topics like solar fuels, artificial leaf, photoelectrochemistry, fuel cells, bioalgal fuel, and solar islands.
