THE AMAZON IS NOT THE LUNGS OF THE WORLD - KNOW HERE IS WHY?

AMAZON IS NOT THE LUNGS OF THE WORLD

WE ALL HAVE HEARD THAT AMAZON IS THE LUNGS OF THE WORLD AND THE LEVEL OF OXYGEN WILL GO DOWN IF AMAZON RAIN FOREST IS NOT THERE. 

 IS THAT TRUE, NO IF IT IS FALSE THEN WHY? IF IT DOESN'T PRODUCE THAT MUCH WHERE DOES OXYGEN COME FROM THEN, WHY THEY ARE TELLING 20% OXYGEN.

WHY NOT AMAZON?

WE NEED TO UNDERSTAND THAT JUST LIKE NEPHRONS THE UNIT OF THE KIDNEY, THE TREES ARE THE UNIT OF THE FOREST, SO LET US UNDERSTAND TREES FIRST IN DAY TIME THE TREES PRODUCE OXYGEN BY PHOTOSYNTHESIS.

AND DURING NIGHT TIME AMAZON FOREST ALSO JUST LIKE US UNDERGO A PROCESS CALLED CELLULAR RESPIRATION  IN WHICH THEY INTAKE O2 AND OXIDISE THE GLUCOSE TO GET ENERGY. (AN CATABOLIC PROCESS)THEY ALSO JUST CONSUME OXYGEN JUST LIKE US.

 

THERE IS ALSO ANOTHER FACT THAT WE HAVE LESS CO2 WHEN COMPARED TO OXYGEN, SO HOW CAN THE TREES PRODUCE OXYGEN IN  LARGE AMOUNTS.

HOW DID THE NO 20% COME IN?

LET ME EXPLAIN TO YOU THAT,

 Yadvinder Malhi, an ecosystem ecologist at Oxford University’s Environmental Change Institute, SAYS THAT  THE TOTAL OXYGEN PRODUCED FROM  PHOTOSYNTHESIS  LAND IS OF 330pg OF O2,

AND IN THAT 54pg OF O2 IS FROM AMAZON, WHEN YOU PUT PERCENTAGE FOR IT YOU WILL GET 16% ( JUST ROUND OF TO 20%)

BUT 
        OCEAN ALSO PRODUSE 240 pg OF OXYGEN IN A YEAR. 
   
          WHEN YOU ADD OCEAN + LAND OXYGEN  = WE GET 570 pg OF OXYGEN ALL OVER
 IN THAT AMAZON CONTRIBUTION IS JUST 9%.

AND AS I SAID BEFORE TREES CONSUME  OXYGEN DURING CELLULAR RESPIRATION BUT AT A SLOWER RATE AND NET GAIN WILL BE LESS.

THE MICROORGANISM USES OXYGEN TO DECOMPOSE DEAD AND DECAYING MATTER IN FORESTS IN THE PROCESS CALLED HETEROTOPIC RESPIRATION.

WHERE DOES OXYGEN COME FROM?

THE WE BREATH ARE NOT FORMED AT ONCE THIS PROCESS TAKE BILLIONS OF YEARS, BUT FOR NOW, THE LEVEL IS MAINTAINED BY PLANTS AND TREES AND PHYTOPLANKTON IN FRESHWATER OCEANS, ETC., THE IS ALSO SOME NET INCREASE IN OXYGEN, BUT THEY ARE ALL CONSUMED BY FOSSIL FUELS WHICH INCREASE CARBON DIOXIDE IN OUR ATMOSPHERE.

PROCHLOROCOCCUS IS ONE OF THE PHYTOPLANKTON THAT IS THE LEADING O2 PRODUCER ON OUR PLANET EARTH. THE OXYGEN CONSUMED BY US ONE IN EVERY 5 BREATHS IS PRODUCED BY THEM. 

Great Oxidation Event 

WHEN WE LOOK BACK INTO EVOLUTION CYANOBACTERIA  THAT INCREASE OUT OXYGEN IN EARTH, WHICH LEADS TO THE DEATH OF MANY ANAEROBIC ORGANISMS.

THIS MEANS AMAZON FOREST HAS NO USE?

NO, ITS COMPLETELY WRONG, NOT ONLY AMAZON FOREST BUT ALL FOREST 

HAVE SOME VALUE IN OUR EARTH. 

                                               * THEY PROVIDE SHELTER FOR SPECIES.

 

                                               *THEY HELP IN MAINTAINING A MOISTURE  ENVIRONMENT.

                                               *THEY HELP IN MAINTAINING THE RAINFALL CYCLE.
