Where Dose The Oxygen Go When Trees Get Cut Down?
This is one of the great green myths. Trees do give out oxygen during the day, but they respire carbon dioxide at night, so the net gain is tiny. Referring to rainforests as ‘the lungs of the world’ is just nonsense – especially when you consider how lungs work! Studies show that fractional oxygen pressure over the Sahara desert is exactly the same as that over the Amazon rainforest, no extra oxygen at all due to all those trees.
