Oxygen

[Victor Frankenstein]

You know how oxygen is released as a byproduct of photosynthesis by plants, how does this affect the amount of oxygen in the air in the winter season in the areas when all plants are frozen ?

[Andre]

Not to worry, the variation in oxygen due to all kind of processes is infinitesimal small. Also, when it's winter on one hemisphere it's summer on another, cancelling each other out.

1)In Sahara,it's the heat that kills u,not the lack of plants (and maybe oxygen :confused: :tongue2: )
2)At the poles,it's the cold that kills u,not the lack of plants (and probably oxygen :confused: :tongue2: ).
3)As for the jungle,well,there's more than enough,plants and oxygen,but usually the humidity,insects and probably wild beasts will kill u as well.

Coclusion:Live in city!!NO_{2} and SO_{2} are less lethal. :tongue2:
