How clean is the air we breathe?: Carl Zimmer

Scientists have been studying airborne diseases for centuries but
their warnings were often overlooked. Carl Zimmer is an
award-winning New York TImes columnist and the author of 15 books
about science. He helps us unpack the history of airborne diseases,
how public health can cling to outdated beliefs and how history
predicted our response to COVID-19. Carl reveals the hidden story
of airborne transmission and what it means for the air we share
today.
