This course will introduce students to the development and limits of sustainability and will engage students in the discovery of the importance of chemistry in everyday sustainable life at the personal and environmental levels. The course will review the evolution of sustainability to enable students to understand how informed decisions can be made. A molecular view of life will be connected to the essential components of food we need to sustain a healthy mind and body over a lifetime. The role of drugs to solve functional problems of biology will be described with a few examples. The nature of chemicals needed to provide an enhanced quality of daily life at home and personal care will be discussed.
