Conspicuous by it's absence from the professor's litany of threats facing humanity in the 21st century is capitalism.

Now "too big to fail," turbocharged by financialization, spread throughout the world courtesy of "globalization" and, in its new, virulent form of neoliberalism,  freed of any notion of social obligation beyond "market justice," modern capitalism fuels injustice, violence and inequality and provides substance for the spectacle that distracts humanity from the daily degradation of the environment and human relationships. 

It's astonishing that capitalism is able to enforce its hegemony by hiding in plain sight, masking itself as a fundamental and unseen element associated with human existence rather than as an historical phenomenon with a short (in historical terms) bloody and troubled history.
