11. What are the effects of using and producing different matter types?

“What are the effects of using and producing different matter types?” is a question of consequence evaluation, because chemistry depends on context and affects the human experience. The life cycles of materials, including production, consumption, and disposal, have benefits, costs, and risks in many dimensions. These include social, economic, political, ethical, environmental, and ecological consequences. While the ultimate aim of chemistry is to improve the human condition, the design of chemical processes involves making decisions based on limiting consumption of energy, using renewable resources, and reducing or eliminating production of toxic byproducts. This chemical thinking question is often central to sustainable action work, such as evaluating which refrigerants are better than Freon, or designing a greener battery.
