The infamous overpopulation bet: Simon vs. Ehrlich - Soraya Field Fiorio
Discover an infamous bet between two professors, which sought to predict whether the earth would run out of resources due to a growing human population. -- In 1980, Paul Ehrlich and Julian Simon bet $1,000 on a question with stakes that couldn’t be higher: would the earth run out of resources to sustain a growing human population? They bet $200 on the price of five metals. If the price of a metal decreased or held steady over the next decade, Simon won. If the price increased, Ehrlich won. So, what happened? Soraya Field Fiorio investigates. Lesson by Soraya Field Fiorio, directed by Avi Ofer.

Why is pneumonia so dangerous? - Eve Gaus and Vanessa Ruiz
Explore how pneumonia attacks the tiny air sacs in your lungs and how your immune system works to fight off the infection. -- Every time you breathe, air travels down the trachea, through a series of channels, and then reaches little clusters of air sacs in the lungs. These tiny sacs facilitate a crucial exchange: allowing oxygen from the air we breathe into the bloodstream and clearing out carbon dioxide. Pneumonia wreaks havoc on this exchange system. Eve Gaus and Vanessa Ruiz detail how pneumonia attacks the lungs. Lesson by Eve Gaus and Vanessa Ruiz, directed by Artrake Studio.
