Traditionally, security has often been narrowly viewed through the lens of military defense and acquitision of weapons. This view must change. Today and increasingly in the future, every nation's security will depend more and more on a new mindset: the security of everyone will hinge on cooperative means to ensure adequate energy, food, and water. However, humanity is on an unsustainable path in use of these resources. Increasing competition for scarcer supplies could lead to major armed conflict or other massive suffering. Dr. Ferguson will discuss the role of engineers and scientists in developing and deploying science and technology to achieve greater security for all nations.
