This nonsense, one of many environmental myths, is often repeated, like a mantra. Yet, some time ago, even the unsuspected Brazilian magazine Super Interessantepublished this revealing comment:
‘Lung of the world.’ What do you think when you hear hearing this expression? It can only be that the Amazon is the world’s largest producer of oxygen, which keeps the earth alive! It turns out that this ‘lung of the world’ story is sheer nonsense. In fact, it is the seaweed that does most of that work by injecting into the atmosphere almost 55 percent of all the oxygen produced on the planet. Furthermore, according to scientists, forests like the Amazon are environments in ecological climax. This means that they consume all or almost all the oxygen they produce.
Oxygen production around the world
- Seaweed – 54.7%
- Woods and forests – 24.9%
- Steppes, fields and pastures – 9.1%
- Cultivated areas – 8.0%
- Freshwater algae – 0.3%
