It is important for teachers to make connections between science classes. Areas that chemistry and biology can be connected is with the discussions of acids and bases with buffer systems in our body, blood, and pH as it relates to stomach acid. The discussion of reaction kinetics and how enzymes and catalyists work to speed up a reaction with out being changed permanently. The role of energy in chemical reactions and how that energy is used to run the body's systems. In addition discussions on biological systems used in other areas of students life. In waste water treatment plants bacteria is used to convert toxic waste into safe natural forms of nitrogen, carbon dioxide and water. "One of the major ways to reduce pollution is to move the elemental balance of chemical technology closer to the elemental balance of life, wherever possible." The shift of technology to reduce pollution by more and more natural means. The example earlier with waste water treatments plants is one example. The use of photogalvanic cells and wind power reduce the need for burning coal and oil for energy. National Public Radio aired a story of the use of wind mills, the possible change in world air currents and the effect on global temperatures. Scientists calculated that if enough wind mills where used to generate the world's energy needs the change would include a slight cooling at the poles and slight warming at the equator. This small change would be greatly off set from the reduction of green house gases produced by the combustion of hydrocarbons.
