Austria has a Pavilion at this event entitled “Forest for the Senses” (“Wald für die Sinne”). The Austrian pavilion attracts many visitors and has received an award. However, what is more important to me is the production of oxygen, the details of which can be read on the website:

THE AUSTRIAN PAVILION PRODUCES OXYGEN

FOR 1 800 PEOPLE PER HOUR

TIP: If so much oxygen can be produced on an area of 2000m2, how much more could be produced with tree plantations to improve the quality of life for humanity?
