If the Oceans Die will we run out of Oxygen?  Some say yes.  The world’s oceans are also know as the lungs of our planet.  As much as 70% of the world’s oxygen comes from tiny plants called phytoplankton.  Sadly since the  1950 there has been a 40% decline in their numbers.  Besides supplying most of the oxygen we humans breath phytoplankton also provides food for most of the ocean’s creatures.  So while I can’t answer the question definitely, if there is even a remote chance that if the world’s ocean’s die we lose 70% of the oxygen we breath is it worth taking the chance?
