The intent of this coursebook is to inspire and empower you by providing knowledge, tools and resources. For this closing, instead of providing more resources, we submit that the most important resource is you. All humans on the planet have a role to play and will influence, in however small or large a scope, the future. It is our sincere hope that we have inspired you to learn more and apply some of the lessons from the coursebook for your happiness, the well-being of others and the sustainability of our beautiful Earth.
