Do you ever wonder about the purpose of life? Why are we all here and what are we doing with our lives? We live in an unprecedented time full of amazing opportunities on the one hand and terrible catastrophes on the other. But for the typical person working a 9-to-5 job (or more likely a 12 hour shift these days), it is likely that neither of these possibilities even registers on their mind.
Do you remember the movie Spaceballs? There is a scene in which President Skroob, played by Mel Brooks, reaches into his desk drawer to open a can of clean “Perri-air” after assuring a news agency that “there is absolutely no air shortage whatsoever.” While it may seem ludicrous that there would ever be a scarcity of clean air, living in polluted cities such as Beijing, Manila, or Los Angeles shows that clean air is not as abundant as it once was.
