The majority of oxygen produced (up to 90%) is by plankton, this includes algae and a plethora of other organisms you probably have never heard of. The Amazon serves as a scapegoat for environmentalists, being anything the zeitgeist at the time necessitates it to be. Coccolithophores, ever heard of that beautiful creation? Just another toy in the evolution heresy.....

Another aspect that the enviro-wacko's have no idea about.

While it's probably closer to 70 or 80%, it is true that the organisms of the oceans provide for FAR more of the earth's oxygen than the rainforests or other sources. [1][2]
