This week, Geographer and Arizona State University professor, Martin Pasqualetti joins Abby in the classroom to help with explaining the Keystone XL Pipeline.

Martin provides both a private and public sector view on the Keystone XL Pipeline and its impact on oil distribution and the environment. Later, Martin explains the key to understanding this energy crisis is to survey the future of climate change and renewable energy.
