Ein Beispiel daf\u00fcr ist, dass wir Kohlendioxid ausatmen, Pflanzen und winzige Lebewesen wie Algen im Ozean es jedoch aufnehmen und wieder in Sauerstoff umwandeln, den wir dann wieder einatmen k\u00f6nnen.

Zum Gl\u00fcck ist der NASA-Astronaut Stephen Bowen zur Stelle, um Paxi das \u201cClosed-Loop-System\u201d zu erkl\u00e4ren, das es Astronauten erm\u00f6glicht, l\u00e4nger im Weltraum zu leben, und sogar Geld spart!<\/p>\n<p>Lange Zeit bezogen Astronauten ihren Sauerstoff aus Wasser (das aus Wasserstoff und Sauerstoff besteht), das von der Erde geliefert wurde.
