It’s also commonly said that “the Amazon Rainforest is the lungs of the planet, producing 1/4 of Earth’s oxygen.  Yes and no.  Being such a huge aggregation of plants (making oxygen through photosynthesis), it does produce 20 times more oxygen than humans need.  But none of




Unfortunately, as with other oceanic organisms, warming ocean temperatures due to climate disruption slow the growth of diatoms.  The primary function of diatoms are as phytoplanktons making oxygen.  Most data sources attribute 50% of the oxygen on Earth to diatoms, though some estimates are even higher.  However, a study done at the University of Leicester has shown that if ocean temperatures rise around six degrees Celsius, oxygen production by phytoplankton could cease by disrupting the process of photosynthesis.  The study’s lead analyst said “About two-thirds of the planet’s total atmospheric oxygen is produced by ocean phytoplankton, and therefore cessation would result in the depletion of atmospheric oxygen on a global scale.  This would likely result in the mass mortality of animals and humans” –
