A human ecology course teaches students about sustainability and how geography, social constructs and even economics play a role. Students may benefit from an interdisciplinary study combined with real-life experience to understand the resources and communication needed to create a sustainable life.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.

Online learning refers to use of electronic media and information and communication technologies (ICT) in education. With online learning one has the flexibility to access their studies at any time and from anywhere they can log on.
